Pull clk updates from Stephen Boyd:
"This time around we have four lines of diff in the core framework,
removing a function that isn't used anymore. Otherwise the main new
thing for the common clk framework is that it is selectable in the
Kconfig language now. Hopefully this will let clk drivers and clk
consumers be testable on more than the architectures that support the
clk framework. The goal is to introduce some Kunit tests for the
framework.
Outside of the core framework we have the usual set of various driver
updates and non-critical fixes. The dirstat shows that the new
Baikal-T1 driver is the largest addition this time around in terms of
lines of code. After that the x86 (Intel), Qualcomm, and Mediatek
drivers introduce many lines to support new or upcoming SoCs. After
that the dirstat shows the usual suspects working on their SoC support
by fixing minor bugs, correcting data and converting some of their DT
bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix
clock support on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and
clk-pllv3 drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support
aarch32 mode on aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using
composite clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102
defined bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx
- Updates and fixup HDMI and video clocks on Meson8b
- Fixup reset polarity on Meson8b
- Fix GPU glitch free mux switch on Meson gx and g12
- A minor fix for the currently unused suspend/resume handling on
Renesas RZ/A1 and RZ/A2
- Two more conversions of Renesas DT bindings to json-schema
- Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+"
