2d945dde7f This is the usual collection of primarily clk driver updates. The big part of 
the diff is all the new Qualcomm clk drivers added for a few SoCs they're
 working on. The other two vendors with significant work this cycle are Renesas
 and Amlogic. Renesas adds a bunch of clks to existing drivers and supports some
 new SoCs while Amlogic is starting a significant refactoring to simplify their
 code.
 
 The core framework gained a pair of helpers to get the 'struct device' or
 'struct device_node' associated with a 'struct clk_hw'. Some associated KUnit
 tests were added for these simple helpers as well. Beyond that core change
 there are lots of little fixes throughout the clk drivers for the stuff we see
 every day, wrong clk driver data that affects tree topology or supported
 frequencies, etc. They're not found until the clks are actually used by some
 consumer device driver.
 
 New Drivers:
  - Global, display, gpu, video, camera, tcsr, and rpmh clock controller for the
    Qualcomm Milos SoC
  - Camera, display, GPU, and video clock controllers for Qualcomm QCS615
  - Video clock controller driver for Qualcomm SM6350
  - Camera clock controller driver for Qualcomm SC8180X
  - I3C clocks and resets on Renesas RZ/G3E
  - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
    Renesas RZ/V2H(P) and RZ/V2N
  - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
  - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
  - Ethernet clocks and resets on Renesas RZ/G3E
  - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
    (R9A09G087) SoCs
  - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
  - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
    RZ/V2N
 
 Updates:
  - Support atomic PWMs in the PWM clk driver
  - clk_hw_get_dev() and clk_hw_get_of_node() helpers
  - Replace round_rate() with determine_rate() in various clk drivers
  - Convert clk DT bindings to DT schema format for DT validation
  - Various clk driver cleanups and refactorings from static analysis tools and
    possibly real humans
  - A lot of little fixes here and there to things like clk tree topology,
    missing frequencies, flagging clks as critical, etc. The full details are in
    the commits and sub-tree merge logs

0f46f50845 soc: driver updates for 6.17 
Changes are all over the place, but very little sticks out as
 noteworthy.
 
 There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
 I/O chip, along with hooking it up to the pinctrl and clk frameworks.
 
 The reset controller and memory subsystems have mainly small updates,
 but there are two new reset drivers for the K230 and VC1800B SoCs,
 and new memory driver support for Tegra264.
 
 The ARM SMCCC and SCMI firmware drivers gain a few more features that
 should help them be supported across more environments. Similarly,
 the SoC specific firmware on Tegra and Qualcomm get minor enhancements
 and chip support.
 
 In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
 overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
 grow to support more chips, while the Hisilicon, Mediatek and Renesas
 drivers see mostly janitorial fixes.

Pull power management updates from Rafael Wysocki:
 "As is tradition, cpufreq is the part with the largest number of
  updates that include core fixes and cleanups as well as updates of
  several assorted drivers, but there are also quite a few updates
  related to system sleep, mostly focused on asynchronous suspend and
  resume of devices and on making the integration of system suspend
  and resume with runtime PM easier.

  Runtime PM is also updated to allow some code duplication in drivers
  to be eliminated going forward and to work more consistently overall
  in some cases.

  Apart from that, there are some driver core updates related to PM
  domains that should help to address ordering issues with devm_ cleanup
  routines relying on PM domains, some assorted devfreq updates
  including core fixes and cleanups, tooling updates, and documentation
  and MAINTAINERS updates.

  Specifics:

54edba916e clk: thead: th1520-ap: Describe mux clocks with clk_mux 
Mux clocks are now described with a customized ccu_mux structure
consisting of ccu_internal and ccu_common substructures, and registered
later with devm_clk_hw_register_mux_parent_data_table(). As this helper
always allocates a new clk_hw structure, it's extremely hard to use mux
clocks as parents statically by clk_hw pointers, since CCF has no
knowledge about the clk_hw structure embedded in ccu_mux.

This scheme already causes issues for clock c910, which takes a mux
clock, c910-i0, as a possible parent. With mainline U-Boot that
reparents c910 to c910-i0 at boottime, c910 is considered as an orphan
by CCF.

This patch refactors handling of mux clocks, embeds a clk_mux structure
in ccu_mux directly. Instead of calling devm_clk_hw_register_mux_*(),
we could register mux clocks on our own without allocating any new
clk_hw pointer, fixing c910 clock's issue.

Enabling runtime PM without explicitly resuming the device caused
the power domain cut off after clk_register() is called. As a result,
a crash happens when the clock hardware provider is added and attempts
to access the BLK_CTL register.

Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable()
and getting rid of the pm_runtime_disable() in the cleanup path.

>From the build perspective, the videocc-sm8550 driver doesn't depend on
having one of the GCC drivers enabled. It builds just fine without the GCC
driver. In practice, it doesn't make much sense to have it enabled without
the GCC driver, but currently this extra dependency is inconsistent with
most of the other VIDEOCC entries in Kconfig. This can easily cause
confusion when you see the VIDEOCC options for some of the SoCs but not for
all of them.

Let's just drop the depends line to allow building the videocc driver
independent of the GCC selection. Compile testing with randconfig will also
benefit from keeping the dependencies minimal.
