License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

Each controller has a memory range on which flash devices contents are mapped. Each device is assigned a window that can be changed at bootime with the Segment Address Registers. Each SPI flash device can then be accessed in two modes: Command and User. When in User mode, SPI transfers are initiated with accesses to the memory segment of a device. When in Command mode, memory operations on the memory segment of a device generate SPI commands automatically using a Control Register for the settings. This initial patch adds support for User mode. Command mode needs a little more work to check that the memory window on the AHB bus fits the device size. It will come later when support for direct mapping is added. Single and dual mode RX transfers are supported. Other types than SPI are not supported.

spi: Add Analog Devices AXI SPI Engine controller support This patch adds support for the AXI SPI Engine controller which is a FPGA soft-peripheral which is used in some of Analog Devices' reference designs. The AXI SPI Engine controller is part of the SPI Engine framework[1] and allows memory mapped access to the SPI Engine control bus. This allows it to be used as a general purpose software driven SPI controller. The SPI Engine in addition offers some optional advanced acceleration and offloading capabilities, which are not part of this patch though and will be introduced separately. At the core of the SPI Engine framework is a small sort of co-processor that accepts a command stream and turns the commands into low-level SPI transactions. Communication is done through three memory mapped FIFOs in the register map of the AXI SPI Engine peripheral. One FIFO for the command stream and one each for transmit and receive data. The driver translates a spi_message in a command stream and writes it to the peripheral which executes it asynchronously. This allows it to perform very precise timings which are required for some SPI slave devices to achieve maximum performance (e.g. analog-to-digital and digital-to-analog converters). The execution flow is synchronized to the host system by a special synchronize instruction which generates a interrupt.

spi: add driver for BCM2835 The BCM2835 contains two forms of SPI master controller (one known simply as SPI0, and the other known as the "Universal SPI Master", in the auxilliary block) and one form of SPI slave controller. This patch adds support for the SPI0 controller. This driver is taken from Chris Boot's repository at git://github.com/bootc/linux.git rpi-linear as of commit 6de2905 "spi-bcm2708: fix printf with spurious %s". In the first SPI-related commit there, Chris wrote: Thanks to csoutreach / A Robinson for his driver which I used as an inspiration. You can find his version here: http://piface.openlx.org.uk/raspberry-pi-spi-kernel-driver-available-for Changes made during upstreaming: * Renamed bcm2708 to bcm2835 as per upstream naming for this SoC. * Removed support for brcm,realtime property. * Increased transfer timeout to 30 seconds. * Return IRQ_NONE from the IRQ handler if no interrupt was handled. * Disable TA (Transfer Active) and clear FIFOs on a transfer timeout. * Wrote device tree binding documentation. * Request unnamed clock rather than "sys_pclk"; the DT will provide the correct clock. * Assume that tfr->speed_hz and tfr->bits_per_word are always set in bcm2835_spi_start_transfer(), bcm2835_spi_transfer_one(), so no need to check spi->speed_hz or tft->bits_per_word. * Re-ordered probe() to remove the need for temporary variables. * Call clk_disable_unprepare() rather than just clk_unprepare() on probe() failure. * Don't use devm_request_irq(), to ensure that the IRQ doesn't fire after we've torn down the device, but not unhooked the IRQ. * Moved probe()'s call to clk_prepare_enable() so we can be sure the clock is enabled if the IRQ handler fires immediately. * Remove redundant checks from bcm2835_spi_check_transfer() and bcm2835_spi_setup(). * Re-ordered IRQ handler to check for RXR before DONE. Added comments to ISR. * Removed empty prepare/unprepare implementations. * Removed use of devinit/devexit. * Added BCM2835_ prefix to defines.

spi: cadence: add support for Cadence XSPI controller This patch adds driver for Cadence's XSPI controller. It supports 3 work modes. 1. ACMD (auto command) work mode ACMD name is because it uses auto command engine in the controller. It further has 2 modes PIO and CDMA (command DMA). The CDMA work mode is dedicated for high-performance application where very low software overhead is required. In this mode the Command Engine is programmed by the series of linked descriptors stored in system memory. These descriptors provide commands to execute and store status information for finished commands. The PIO mode work mode is dedicated for single operation where constructing a linked list of descriptors would require too much effort. 2. STIG (Software Triggered Instruction Generator) work mode In STIG mode, controller sends low-level instructions to memory. Each instruction is 128-bit width. There is special instruction DataSequence which carries information about data phase. Driver uses Slave DMA interface to transfer data as only this interface can be used in STIG work mode. 3. Direct work mode This work mode allows sending data without invoking any command through the slave interface. Currently only STIG work mode is enabled, remaining work modes will be added later.

spi: dw: Add Baikal-T1 SPI Controller glue driver Baikal-T1 is equipped with three DW APB SSI-based MMIO SPI controllers. Two of them are pretty much normal: with IRQ, DMA, FIFOs of 64 words depth, 4x CSs, but the third one as being a part of the Baikal-T1 System Boot Controller has got a very limited resources: no IRQ, no DMA, only a single native chip-select and Tx/Rx FIFO with just 8 words depth available. In order to provide a transparent initial boot code execution the Boot SPI controller is also utilized by an vendor-specific IP-block, which exposes an SPI flash direct mapping interface. Since both direct mapping and SPI controller normal utilization are mutual exclusive only one of these interfaces can be used to access an external SPI slave device. That's why a dedicated mux is embedded into the System Boot Controller. All of that is taken into account in the Baikal-T1-specific DW APB SSI glue driver implemented by means of the DW SPI core module.

spi: lantiq-ssc: add support for Lantiq SSC SPI controller This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.

spi: add driver for J-Core SPI controller The J-Core "spi2" device is a PIO-based SPI master controller. It differs from "bitbang" devices in that that it's clocked in hardware rather than via soft clock modulation over gpio, and performs byte-at-a-time transfers between the cpu and SPI controller.

spi: add support for mediatek spi-nor controller This is a driver for mtk spi-nor controller using spi-mem interface. The same controller already has limited support provided by mtk-quadspi driver under spi-nor framework and this new driver is a replacement for the old one. Comparing to the old driver, this driver has following advantages: 1. It can handle any full-duplex spi transfer up to 6 bytes, and this is implemented using generic spi interface. 2. It take account into command opcode properly. The reading routine in this controller can only use 0x03 or 0x0b as opcode on 1-1-1 transfers, but old driver doesn't implement this properly. This driver checks supported opcode explicitly and use (1) to perform unmatched operations. 3. It properly handles SFDP reading. Old driver can't read SFDP due to the bug mentioned in (2). 4. It can do 1-2-2 and 1-4-4 fast reading on spi-nor. These two ops requires parsing SFDP, which isn't possible in old driver. And the old driver is only flagged to support 1-1-2 mode. 5. It takes advantage of the DMA feature in this controller for long reads and supports IRQ on DMA requests to free cpu cycles from polling status registers on long DMA reading. It achieves up to 17.5MB/s reading speed (1-4-4 mode) which is way faster than the old one. IRQ is implemented as optional to maintain backward compatibility.

spi/pxa2xx: break out the private DMA API usage into a separate file The PXA SPI driver uses PXA platform specific private DMA implementation which does not work on non-PXA platforms. In order to use this driver on other platforms we break out the private DMA implementation into a separate file that gets compiled only when CONFIG_SPI_PXA2XX_PXADMA is set. The DMA functions are stubbed out if there is no DMA implementation selected (i.e we are building on non-PXA platform). While we are there we can kill the dummy DMA bits in pxa2xx_spi.h as they are not needed anymore for CE4100. Once this is done we can add the generic DMA engine support to the driver that allows usage of any DMA controller that implements DMA engine API.

spi/rockchip: add driver for Rockchip RK3xxx SoCs integrated SPI In order to facilitate understanding, rockchip SPI controller IP design looks similar in its registers to designware.

From the point of view of an SPI slave protocol handler, an SPI slave controller looks almost like an ordinary SPI master controller. The only exception is that a transfer request will block on the remote SPI master, and may be cancelled using spi_slave_abort().
