Pull clk updates from Stephen Boyd:
"I'm actually surprised this time. There aren't any new Qualcomm SoC
clk drivers. And there's zero diff in the core clk framework.
Instead we have new clk drivers for STM and Sophgo, with
Samsung^WGoogle in third for the diffstat because they introduced HSI0
and HSI2 clk drivers for Google's GS101 SoC (high speed interface
things like PCIe, UFS, and MMC).
Beyond those big diffs there's the usual updates to various clk
drivers for incorrect parent descriptions or mising
MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.
New Drivers:
- STM32MP257 SoC clk driver
- Airoha EN7581 SoC clk driver
- Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
- Loongson-2k0500 and Loongson-2k2000 SoC clk driver
- Add HSI0 and HSI2 clock controllers for Google GS101
- Add i.MX95 BLK CTL clock driver
Updates:
- Allocate clk_ops dynamically for SCMI clk driver
- Add support in qcom RCG and RCG2 for multiple configurations for
the same frequency

Define "clock-<freq>" as the preferred node name for fixed-clock and
fixed-factor-clock where <freq> is the output frequency of the clock.
There isn't much of an existing pattern for names of these nodes. The
most frequent patterns are a prefix or suffix of "clk", but there's a
bunch that don't follow any sort of pattern. We could use
"clock-controller-.*", but these nodes aren't really a controller in any
way. So let's at least align with part of that and use 'clock-'.
For now this only serves as documentation as the schema still allows
anything to avoid lots of additional warnings for something low priority
to fix. Once a "no deprecated" mode is added to the tools, warnings can
be enabled selectively.

The driver will be modified (in the next commits) to be able to specify
individual power domain IDs for each IP. The driver will still
support #power-domain-cells = <0>, thus, previous users are not
affected.
The #power-domain-cells = <1> has been instantiated only for RZ/G3S at
the moment, as individual platform clock drivers need to be adapted for
this to be supported on the rest of the SoCs.
Also, the description for #power-domain-cells is updated with links to
per-SoC power domain IDs.

Add dt-schema documentation and clock IDs for the high speed interface
0 HSI0 clock management unit. This is used (amongst others) for USB.
While the usual (sed) script has been used to derive the linux clock
IDs from the data sheet, one manual tweak was applied to fix a typo
which we don't want to carry:
HSI0_USPDPDBG_USER -> HSI0_USBDPDBG_USER (note USB vs USP).

Convert the .txt documentation to .yaml with some adjustments.
* APQ8064/IPQ8064/MSM8960 compatibles are dropped since their HFPLLs are
a part of GCC so there is no need for a separate compat entry.
* Change the MSM8974 compatible to follow the updated naming schema.
Theis compatible is not used upstream yet.
* Add qcs404-hfpll. QCS404 currently uses qcom,hfpll. Mark that as
deprecated since every SoC appears to need different driver data so
"qcom,hfpll" makes no sense to keep

Pull clk updates from Stephen Boyd:
"Not a ton of stuff happening in the clk framework. We got some more
devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that
into a pmdomain that drivers attach instead, but this API should help
drivers simplify in the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates
that are dominated by the major phone SoC vendors (Samsung and
Qualcomm) and the non-critical driver fixes for things like incorrect
topology descriptions and wrong registers or bit fields. More details
are below, but I'd say that it looks pretty ordinary. The only thing
that really jumps out at me is the Renesas clk driver that's ignoring
clks that are assigned to remote processors in DeviceTree. That's a
new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1
Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock
controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers
and the output of each divider feed individual hardware blocks
(e.g. CAN, Crypto, eMMC); individual hardware block drivers need to
control their clocks thus clock driver support was added for all
MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk
drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd
to Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC
driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC
driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk
driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk
driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall
clock-number from the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked
clocks
- Minor clean-ups and error handling improvements in both
composite-8m and SCU i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the
Multi Core Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI
will get proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing
it for supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on
Renesas R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the
Renesas clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC

Qualcomm ARM64 DeviceTree updates for v6.9
Four variants of Samsung Galaxy Core Prime and Grand Prime, built on
MSM8916, and the Hardware Development Kit (HDK) for SM8550, are
introduced.
On X Elite audio and compute remoteprocs, IPCC, PCIe, AOSS QMP, SMP2P,
TCSR, USB, display, audio, and soundwire support is introduced, and
enabled across the CRD and QCP devices.
For SM8650 PCIe controllers are moved to GIC-ITS and msi-map-mask is
defined. Missing qlink-logging reserved-memory region is added for the
modem remoteproc. FastRPC compute contexts are marked dma-coherent.
Audio, USB Type-C and PM8010 support is introduced across MTP and QRD
devices.
GPU cooling devices are hooked up across MSM8916, MSM8939, SC8180X,
SDM630, SDM845, SM6115, SM8150, SM8250, SM8350, and SM8550.
UFS PHY clocks are corrected across MSM8996, MSM8998, SC8180X, SC8280XP,
SDM845, SM6115, SM6125, SM8150, SM8250, SM8350, SM8550, and SM8650.
PCI MSI interrupts are wired up across SM8150, SM8250, SM8350, SM8450,
SM8550, SM8650, SC7280, and SC8180X
On IPQ6018 QUP5 I2C, tsens sand thermal zones are defined. The Inline
Crypto Engine (ICE) is enabled for IPQ9574.
On MSM8953 the GPU and its IOMMU is introduced, the reset for the
display subsystem is also wired up.
VLS CLAMP registers are specified for USB3 PHYs on MSM8998, QCM2290, and
SM6115.
USB Type-C port management is enabled on QRB4210 RB2.
On the SA8295P ADP the MAX20411 regulator powering the GPU rails is
introduced and the GPU is enabled. The first PCI instance on SA8540P
Ride is disabled for now, as a fix for the interrupt storm produced here
has not been presented.
On SA8775P the firmware memory map has changed and is updated. Safety
IRQ is added to the Ethernet controller.
On SC7180 UFS support is introduced and the cros-ec-spi is marked as
wakeup source.
For SC7280 capacity and DPC properties are added, cryptobam definition
is improved to work in more firmware environments, more Chrome-specific
properties are moved out from main dtsi, and cros-ec-spi is maked as a
wakeup source. Slimbus definition is added to the platform.
A missing reserved-memory range is added to Fairphone FP5, PMIC GLINK
and Venus are enabled. LEDs are introduced and voltage settings
corrected on the QCM6490 IDP, and RB3gen2 sees the same voltage changes
and GCC protected clocks are introduced to make the board boot properly.
RPMh sleep stats and a variety of cleanups and fixes are introduced for
SC8180X.
On SC8280XP the additional tsens instances are introduced. Camera
Subsystem and Camera Control Interface (CCI) are added. PMIC die-temp
vadc channels are introduced on the CRD, to allow ADC channels to be
tied to the shared PMIC temp-alarms, to actually report temperature.
On SDM630 USB QMP PHY support is introduced and enabled on the Inforce
IFC6560 board. On the various Sony Xperia XA2 variants WLED is enabled
and configured.
On SM6350 display subsystem interconnects and tsens-based thermal zones
are added. On SM7125 UFS support is added.
On Fairphone FP4, on SM7225, display and GPU are enabled, and firmware
paths are corrected.
SM8150 PCIe controller definitions are corrected.
As with SM8650, the SM8550 the fastrpc compute contexts are marked
dm-coherent, and PCIe controllers are moved to use GIC-ITS. The UFS
controller frequency definition is moved to the generic opp-table.
Touchscreen is enabled on the QRD device.
As usual, a variety of smaller cleanups and corrections to match
DeviceTree bindings and style guidelines are introduced across the
various files.

Document CPU clock management unit compatibles and add corresponding
clock indices. Exynos850 has two CPU clusters (CL0 and CL1), each
containing 4 Cortex-A55 cores. CPU PLLs are generating main CPU clocks
for each cluster, and there are alternate ("switch") clocks that can be
used temporarily while re-configuring the PLL for the new rate. ACLK,
ATCLK, PCLKDBG and PERIPHCLK clocks are driving corresponding buses.
CLK_CLUSTERx_SCLK are actual leaf CPU clocks and should be used to
change CPU rates. Also some CoreSight clocks can be derived from
DBG_USER (debug clock).
