9db481c909 memory: tegra30-emc: fix interconnect registration race
The current interconnect provider registration interface is inherently
racy as nodes are not added until the after adding the provider. This
can specifically cause racing DT lookups to fail.

Switch to using the new API where the provider is not registered until
after it has been fully initialised.

11c7052998 ARM: SoC drivers for 6.3
As usual, there are lots of minor driver changes across SoC platforms
 from  NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
 These usually add support for additional chip variations in existing
 drivers, but also add features or bugfixes.
 
 The SCMI firmware subsystem gains a unified raw userspace interface
 through debugfs, which can be used for validation purposes.
 
 Newly added drivers include:
 
  - New power management drivers for StarFive JH7110, Allwinner D1 and
    Renesas RZ/V2M
 
  - A driver for Qualcomm battery and power supply status
 
  - A SoC device driver for identifying Nuvoton WPCM450 chips
 
  - A regulator coupler driver for Mediatek MT81xxv

memory: renesas-rpc-if: Remove redundant division of dummy
The dummy cycles value was wrongly calculated if dummy.buswidth > 1,
which affects QSPI, OSPI, HyperFlash on various SoCs. We're lucky in
Single SPI case since its dummy.buswidth equals to 1, so the result of
the division is unchanged

This issue can be reproduced using something like the following commands
A. QSPI mode: Mount device with jffs2 format
    jffs2: CLEANMARKER node found at 0x00000004, not first node in block (0x00000000)

B. QSPI mode: Write data to mtd10, where mtd10 is a parition on SPI Flash
storage, defined properly in a device tree

[Correct fragment, read from SPI Flash]

  root@v3x:~# echo "hello" > /dev/mtd10
  root@v3x:~# hexdump -C -n100 /dev/mtd10
  00000000  68 65 6c 6c 6f 0a ff ff  ff ff ff ff ff ff ff ff  |hello...........|
  00000010  ff ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

[Incorrect read of the same fragment: see the difference at offsets 0-3]

  root@v3x:~# echo "hello" > /dev/mtd10
  root@v3x:~# hexdump -C -n100 /dev/mtd10
  00000000  00 00 00 00 68 65 6c 6c  6f 0a ff ff ff ff ff ff  |....hello.......|
  00000010  ff ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

As seen from the result, 4 NULL bytes were inserted before the test data.
Wrong calculation in rpcif_prepare() led to miss of some dummy cycle. A
division by bus width is redundant because it had been performed already
in spi-rpc-if.c::rpcif_spi_mem_prepare()

Fix this by removing the redundant division.

8b3580df15 memory: renesas-rpc-if: Move resource acquisition to .probe()
While the acquired resources are tied to the lifetime of the RPC-IF core
device (through the use of managed resource functions), the actual
resource acquisition is triggered from the HyperBus and SPI child
drivers.  Due to this mismatch, unbinding and rebinding the child
drivers manually fails with -EBUSY:

    # echo rpc-if-hyperflash > /sys/bus/platform/drivers/rpc-if-hyperflash/unbind
    # echo rpc-if-hyperflash > /sys/bus/platform/drivers/rpc-if-hyperflash/bind
    rpc-if ee200000.spi: can't request region for resource [mem 0xee200000-0xee2001ff]
    rpc-if-hyperflash: probe of rpc-if-hyperflash failed with error -16

The same is true for rpc-if-spi.

Fix this by moving all resource acquisition to the core driver's probe
routine.

51de3fc9a8 memory: renesas-rpc-if: Split-off private data from struct rpcif
The rpcif structure is used as a common data structure, shared by the
RPC-IF core driver and by the HyperBus and SPI child drivers.
This poses several problems:
  - Most structure members describe private core driver state, which
    should not be accessible by the child drivers,
  - The structure's lifetime is controlled by the child drivers,
    complicating use by the core driver.

Fix this by moving the private core driver state to its own structure,
managed by the RPC-IF core driver, and store it in the core driver's
private data field.  This requires absorbing the child's platform
device, as that was stored in the driver's private data field before.

ef86b2c280 memory: tegra: Remove clients SID override programming
On newer Tegra releases, early boot SID override programming and SID
override programming during resume is handled by bootloader.
In the function tegra186_mc_program_sid() which is getting removed, SID
override register of all clients is written without checking if secure
firmware has allowed write on it or not. If write is disabled by secure
firmware then it can lead to errors coming from secure firmware and hang
in kernel boot.
Also, SID override is programmed on-demand during probe_finalize() call
of IOMMU which is done in tegra186_mc_client_sid_override() in this same
file. This function does it correctly by checking if write is permitted
on SID override register. It also checks if SID override register is
already written with correct value and skips re-writing it in that case.

Merge tag 'drm-next-2022-12-13' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for

On Tegra234 NVDEC firmware is loaded from a secure carveout, where it
has been loaded by a bootloader. When booting NVDEC, we need to tell it
the address of this firmware, which we can determine by checking the
starting address of the carveout. As such, add an MC API to query the
bounds of carveouts, and add related information on Tegra234.

a2faac3986 ARM: 9263/1: use .arch directives instead of assembler command line flags
Similar to commit a6c30873ee ("ARM: 8989/1: use .fpu assembler
directives instead of assembler arguments").

GCC and GNU binutils support setting the "sub arch" via -march=,
-Wa,-march, target function attribute, and .arch assembler directive.

Clang was missing support for -Wa,-march=, but this was implemented in
clang-13.

The behavior of both GCC and Clang is to
prefer -Wa,-march= over -march= for assembler and assembler-with-cpp
sources, but Clang will warn about the -march= being unused.

clang: warning: argument unused during compilation: '-march=armv6k'
[-Wunused-command-line-argument]

Since most assembler is non-conditionally assembled with one sub arch
(modulo arch/arm/delay-loop.S which conditionally is assembled as armv4
based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is
conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the
.arch assembler directive.

Add a few more instances found in compile testing as found by Arnd and
Nathan.

89aed3cd5c memory: omap-gpmc: wait pin additions
This patch introduces support for setting the wait-pin polarity as well
as using the same wait-pin for different CS regions.

The waitpin polarity can be configured via the WAITPIN<X>POLARITY bits
in the GPMC_CONFIG register. This is currently not supported by the
driver. This patch adds support for setting the required register bits
with the "ti,wait-pin-polarity" dt-property.

The wait-pin can also be shared between different CS regions for special
usecases. Therefore GPMC must keep track of wait-pin allocations, so it
knows that either GPMC itself or another driver has the ownership.

The SPI Multi I/O Bus Controller (RPC-IF) on R-Car Gen4 SoCs is very

of three bits of strobe timing adjustment (STRTIM), and thus requires a
new mask and new settings.

5192481f90 memory: renesas-rpc-if: Clear HS bit during hardware initialization
According to the datasheet, HS bit should be specified to 1 when using
DMA transfer. As DMA transfer is not supported, it should be cleared to
0.

Previously, the driver relied on the HS bit being cleared by prior
firmware but this is not always the case.

Fix this by ensuring the bit is cleared during hardware initialization.

The next generation (revision 1) of the DFL EMIF feature device requires
support for more than 4 memory banks. It does not support the selective
clearing of memory banks. A capability register replaces the previous
control register, and contains a bitmask to indicate the presence of each
memory bank. This bitmask aligns with the previous control register
bitmask that served the same purpose. The control and capability
registers are treated like a C Union structure in order to support both
the new and old revisions of the EMIF device.

89f03984fa OPP: Migrate set-supported-hw API to use set-config helpers
Now that we have a central API to handle all OPP table configurations,
migrate the set-supported-hw family of helpers to use the new
infrastructure.

The return type and parameter to the APIs change a bit due to this,
update the current users as well in the same commit in order to avoid
breaking builds.
