a4b2e6063c firmware: xilinx: Clear IOCTL_SET_SD_TAPDELAY using PM_MMIO_WRITE
In case the tap delay required by Arasan SDHCI is set to 0, the current
embeddedsw firmware unconditionally writes IOU_SLCR SD_ITAPDLY to 0x100
(SD0_ITAPDLYENA=1, SD0_ITAPDLYSEL=0). Previous behavior was to keep the
IOU_SLCR SD_ITAPDLY set to 0x0. There is some sort of difference in the
behavior between SD0_ITAPDLYENA=1/0 with the same SD0_ITAPDLYSEL=0, even
though the behavior should be identical -- zero delay added to rxclk_in
line. The former breaks HS200 training in low temperature conditions.

Write IOU_SLCR SD_ITAPDLY register to 0 using PM_MMIO_WRITE which seem
to allow unrestricted WRITE access (and PM_MMIO_READ which allows read
access) to the entire address space. This way, it is possible to work
around the defect in IOCTL_SET_SD_TAPDELAY design which does not permit
clearing SDx_ITAPDLYENA bit.

Note that the embeddedsw firmware does not permit clearing the SD_ITAPDLY
SD0_ITAPDLYENA bit, this bit can only ever be set by the firmware and it
is often impossible to update the possibly broken firmware.

9cf5b508bd remoteproc updates for v6.2
rproc-virtio device names are now auto generated, to avoid conflicts
 between remoteproc instances.
 
 The imx_rproc driver is extended with support for communicating with and
 attaching to a running M4 on i.MX8QXP, as well as support for
 attaching to the M4 after self-recovering from a crash. Support is
 added for i.MX8QM and mailbox channels are reconnected during the
 recovery process, in order to avoid data corruption.
 
 The Xilinx Zynqmp firmware interface is extended and support for the
 Xilinx R5 RPU is introduced.
 
 Various resources leaks, primarily in error paths, throughout the
 Qualcomm drivers are corrected.
 
 Lastly a fix to ensure that pm_relax is invoked even if the remoteproc
 instance is stopped between a crash is being reported and the recovery
 handler is scheduled.

acd6510dd7 firmware: xilinx: Add TF_A_PM_REGISTER_SGI SMC call
SGI interrupt register and reset is performed by EEMI ioctl
IOCTL_REGISTER_SGI. However, this is not correct use of EEMI call.
SGI registration functionality does not qualify as energy management
activity and so shouldn't be mapped to EEMI call.

This new call will replace IOCTL_REGISTER_SGI and will  be handled by TF-A
specific handler in TF-A. To maintain backward compatibility for a while
firmware driver will still use IOCTL_REGISTER_SGI as fallback strategy if
new call fails or is not supported by TF-A.

This new design also helps to make TF-A as pass through layer for EEMI
calls. So we don't have to maintain PM_IOCTL as EEMI API ID in TF-A.

 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers

f1d0821bf3 firmware: xilinx: Add support for runtime features
Add support for runtime features by using an IOCTL call. The features
 can be enabled or disabled from the firmware as well as the features
 can be configured at runtime by querying IOCTL_SET_FEATURE_CONFIG id.
 Similarly, the user can get the configured values of features by
 querying IOCTL_GET_FEATURE_CONFIG id.

3bad80dab9 Char/Misc and other driver changes for 5.17-rc1
Here is the large set of char, misc, and other "small" driver subsystem
 changes for 5.17-rc1.
 
 Lots of different things are in here for char/misc drivers such as:
 	- habanalabs driver updates
 	- mei driver updates
 	- lkdtm driver updates
 	- vmw_vmci driver updates
 	- android binder driver updates
 	- other small char/misc driver updates
 
 Also smaller driver subsystems have also been updated, including:
 	- fpga subsystem updates
 	- iio subsystem updates
 	- soundwire subsystem updates
 	- extcon subsystem updates
 	- gnss subsystem updates
 	- phy subsystem updates
 	- coresight subsystem updates

 Too many individual changes to summarize, the shortlog contains the full
 details.
 
 All of these have been in linux-next for a while with no reported
 issues.

65ec0a7d24 This is the bulk of the pin control changes for the v5.13 kernel cycle
Core changes:
 
 - A semantic change to handle pinmux and pinconf in explicit order
   while up until now we depended on the semantic order in the
   device tree. The device tree is a functional programming
   language and does not imply any order, so the right thing is
   for the pin control core to provide these semantics.
 
 - Add a new pinmux-select debugfs file which makes it possible to
   go in and select functions for a pin manually (iteratively, at
   the prompt) for debugging purposes.
 
 - Fixes to gpio regmap handling for a new pin control driver
   making use of regmap-gpio.
 
 - Use octal permissions on debugfs files.
 
 New drivers:
 
 - A massive rewrite of the former custom pin control driver for
   MIPS Broadcom devices to instead use the pin control subsystem.
   New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362,
   BCM6368, BCM63268 and BCM6318 SoC variants are implemented.
 
 - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and
   PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs
   on PM8008 are supported.
 
 - Support for the Rockchip RK3568/RK3566 pin controller.
 
 - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and
   X2000.
 
 - Support for Mediatek MTK8195.
 
 - Add a new Xilinx ZynqMP pin control driver.
 
 Driver improvements and non-urgent fixes:
 
 - Modularization and improvements of the Rockchip drivers.
 
 - Some new pins added to the description of new Renesas SoCs.
 
 - Clarifications of the GPIO base calculation in the Intel driver.
 
 - Fix the function names for the MPP54 and MPP55 pins in the Armada
   CP110 pin controller.
 
 - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
 
 - Support for ACPI probing of the Qualcomm SC8180x.
 
 - Fix interrupt clear status on rockchip
 
 - Fix some missing pins on the Ingenic JZ4770, some semantic
   fixes for the behaviour of the Ingenic pin controller.
   Add DMIC pins for JZ4780, X1000, X1500 and X1830.
 
 - A slew of janitorial like of_node_put() calls.

    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

acfdd18591 firmware: xilinx: Use hash-table for api feature check
Currently array of fix length PM_API_MAX is used to cache
the pm_api version (valid or invalid). However ATF based
PM APIs values are much higher then PM_API_MAX.
So to include ATF based PM APIs also, use hash-table to
store the pm_api version status.

Replace the resulting undefined behavior with an error return.
This may break some things that happen to work at the moment
but seems better than randomly overwriting kernel data.

I assume we need additional fixes for the two functions that now
return an error.
