Memory controller drivers for v6.8, part two
Convert all drivers platform remove callback to the "remove_new" which
returns void. Usual rationale from Uwe:
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.

Memory controller drivers for v6.8
Few improvements for Tegra Memory Controller: Override the SID
programming in the device, if firmware or bootloader left it in bypass
mode, e.g. after resuming from suspend. Skip prorgamming the SID, if
given Memory Controller client does not support it.

RISC-V cache drivers for v6.8
The SiFive composable cache driver moves to the cache driver
subdirectory from the drivers/soc and grows support for non-coherent
cache operations. The immediate user for these is the jh7100 SoC, that
a rake of people have on VisionFive v1 or Beagle-V Starlight boards.

RISC-V SoC drivers for v6.8
There's only one set of changes here, the addition of "Auto Update"
support for PolarFire SoC. Auto Update is one of the ways that the FPGA
bitstream can be updated, and the only one suitable for use from Linux
as it does not immediately initiate a reboot when started.
The driver was not accepted in the FPGA manager subsystem as the update
only occurs after a reboot and makes no use of the FPGA manager
framework.

Samsung SoC driver changes for v6.8
1. Add support for Google GS101 SoC to different drivers: clock
controller, serial and watchdog.
The clock driver changes depend on few bindings headers, which I put
in a topic branch with the bindings refactoring and GS101 support,
therefore this this pull request includes that bindings topic branch.
The rest of the bindings topic branch is not necessary here, however
keeping everything together makes it easier to share between
branches. The bindings topic branch is mostly refactoring all the
compatibles to add SoC-specific compatible followed by fallback.
2. Exynos ChipID: recognize ExynosAutov920.

Qualcomm driver updates for v6.8
Support for SM8650 and X1E is added to the LLCC driver, the
LLCC_TRP_ATTR2_CFGn register stride is corrected, and a bug where for
each iteration looping over slices previous settings for dis_cap_alloc
and retain_on_pc are overwritten.
A quirk is introduced in UCSI, for implementations that does not handle
UCSI_GET_PDOS for non-PD partners. With this, USCI support is enabled by
default in pmic_glink. It is later reverted for SC8280XP due reported
errors.
A few memory leaks in error paths of qseecom are taken care of.
A small driver to expose the ADSP PDCharger ULOG debug log is
introduced, to aid debugging issues with pmic_glink.
The identiy of SM8650, PM8937 and a few DSPs are added to the Qualcomm
socinfo driver.
The Qualcomm sleep stats driver is extended to allow getting detailed
statistics about usage of various DDR states. Unfortunately this ABI
does not seem to be stable across platforms, so this addition is dropped
again while the reported problems are investigated further.
Andy is moved from MAINTAINERS to CREDITS. Thank you, Andy.

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.

The gs101 clock defines from the bindings header are derived from the
clock register names found in the datasheet under some certain rules.
The CMU TOP gate clock defines missed to include the required "CMU"
differentiator which will cause collisions with the gate clock defines
of other clock units. Rename the TOP gate clock defines to include "CMU".
Update the clock driver to use the new defines in order to not break
compilation and bisect-ability. There are no device trees that use the
previous defines.

Commit c14e64b46944 ("soc: qcom: llcc: Support chipsets that can
write to llcc") add the support for chipset where capacity based
allocation and retention through power collapse can be programmed
based on content of SCT table mentioned in the llcc driver where
the target like sdm845 where the entire programming related to it
is controlled in firmware. However, the commit introduces a bug
where capacity/retention register get overwritten each time it
gets programmed for each slice and that results in misconfiguration
of the register based on SCT table and that is not expected
behaviour instead it should be read modify write to retain the
configuration of other slices.
This issue is totally caught from code review and programming test
and not through any power/perf numbers so, it is not known what
impact this could make if we don't have this change however,
this feature are for these targets and they should have been
programmed accordingly as per their configuration mentioned in
SCT table like others bits information.
This change brings one difference where it keeps capacity/retention
bits of the slices that are not mentioned in SCT table in unknown
state where as earlier it was initialized to zero.

Commit 73380e2573c3 ("soc: qcom: stats: fix 64-bit division")
Commit e84e61bdb97c ("soc: qcom: stats: Add DDR sleep stats")
The feature itself is rather useful for debugging DRAM power management,
however it looks like the shared RPMh stats data structures differ on
previous SoCs.
Revert its addition for now to un-break booting on these earlier SoCs,
while I try to come up with a better way to enable it conditionally.
