The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

As per the current code base, PM_CLOCK_SETRATE and PM_CLOCK_GETRATE
APIs are not supported for the runtime operations. In the case of
ZynqMP returning an error from TF-A when there is any request to
access these APIs and for Versal also it is returning an error like
NO_ACCESS from the firmware. So, just removing the unused code to
avoid the confusion around these APIs.
Also, there is no issue with the backward compatibility as these APIs
were never used since implemented. Hence no need to bump up the
version of the feature check API as well.

Failure to register SGI for firmware event notification is non-fatal error
when feature is not supported by other modules such as Xen and TF-A. Add
_info level log message for such special case.
Also add XST_PM_INVALID_VERSION error code and map it to -EOPNOSUPP Linux
kernel error code. If feature is not supported or EEMI API version is
mismatch, firmware can return XST_PM_INVALID_VERSION = 4 or
XST_PM_NO_FEATURE = 19 error code.

maximum of 5 arguments as of now (1 EEMI API ID + 4 command arguments).
In order to support new EEMI PM_IOCTL IDs (Secure Read/Write), this
support must be extended to support one additional argument, which
results in a configuration of - 1 EEMI API ID + 5 command arguments.

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.

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.

Here is the big set of char/misc and other small driver subsystem
updates for 5.18-rc1.
Included in here are merges from driver subsystems which contain:
- 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
- phy driver updates and new drivers
- coresight driver updates
- icc driver updates
Individual changes include:
- mei driver updates
- interconnect driver updates
- new PECI driver subsystem added
- vmci driver updates
- lots of tiny misc/char driver updates
There will be two merge conflicts with your tree, one in MAINTAINERS
which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
which also should be easy to resolve.
All of these have been in linux-next for a while with no reported
problems.

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.

- 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

There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
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.

Merge tag 'arm-soc-drivers-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann:
"There are a couple of subsystems maintained by other people that merge
their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
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"
