Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The diff is dominated by the Allwinner A10/A20 SoCs getting converted
to the sunxi-ng framework. Otherwise, the heavy hitters are various
drivers for SoCs like AT91, Amlogic, Renesas, and Rockchip. There are
some other new clk drivers in here too but overall this is just a
bunch of clk drivers for various different pieces of hardware and a
collection of non-critical fixes for clk drivers.
New Drivers:
- Allwinner R40 SoCs
- Renesas R-Car Gen3 USB 2.0 clock selector PHY
- Atmel AT91 audio PLL
- Uniphier PXs3 SoCs
- ARC HSDK Board PLLs
- AXS10X Board PLLs
- STMicroelectronics STM32H743 SoCs
Removed Drivers:
- Non-compiling mb86s7x support
Updates:
- Allwinner A10/A20 SoCs converted to sunxi-ng framework
- Allwinner H3 CPU clk fixes
- Renesas R-Car D3 SoC
- Renesas V2H and M3-W modules
- Samsung Exynos5420/5422/5800 audio fixes
- Rockchip fractional clk approximation fixes
- Rockchip rk3126 SoC support within the rk3128 driver
- Amlogic gxbb CEC32 and sd_emmc clks
- Amlogic meson8b reset controller support
- IDT VersaClock 5P49V5925/5P49V6901 support
- Qualcomm MSM8996 SMMU clks
- Various 'const' applications for struct clk_ops
- si5351 PLL reset bugfix
- Uniphier audio on LD11/LD20 and ethernet support on LD11/LD20/Pro4/PXs2
- Assorted Tegra clk driver fixes"
