linux/drivers/clk/tegra/clk-tegra30.c
Linus Torvalds 28b9aaac4c This is all driver updates, the majority of which is a bunch of new Qualcomm 
clk drivers that dominate the diffstat because we add support for six SoCs from
 that particular vendor. The other big change is the removal of various clk
 drivers that are no longer used now that the kernel is dropping support for
 those SoCs. Beyond that there's the usual non-critical fixes for existing
 drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1
 enabled builds.
 
 Removed Drivers:
  - Remove efm32 clk driver
  - Remove tango4 clk driver
  - Remove zte zx clk driver
  - Remove sirf prima2/atlast clk drivers
  - Remove u300 clk driver
 
 New Drivers:
  - PLL support on MStar/SigmaStar ARMv7 SoCs
  - CPU clks for Qualcomm SDX55
  - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs
  - GCC clks for Qualcomm SM8350
  - GPU clks for Qualcomm SDM660/SDM630
 
 Updates:
  - Video clk fixups on Qualcomm SM8250
  - Improvements for multimedia clks on Qualcomm MSM8998
  - Fix many warnings with W=1 enabled builds under drivers/clk/
  - Support crystal load capacitance for Versaclock VC5
  - Add a "skip recall" DT binding for Silicon Labs' si570 to avoid glitches at boot
  - Convert Xilinx VCU clk driver to a proper clk provider driver
  - Expose Xilinx ZynqMP clk driver to more platforms
  - Amlogic pll driver fixup
  - Amlogic meson8b clock controller dt support clean up
  - Remove mipi clk from the Amlogic axg clock controller
  - New Rockchip rk3368 clock ids related to camera input
  - Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk reparenting
  - A series from Liu Ying that adds some SCU clocks support for i.MX8qxp
    DC0/MIPI-LVDS subsystems
  - A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ, and
    clkout1/2 support for i.MX8MM/MN
  - Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U
  - Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs
  - Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial
    (HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA
    (SYS-DMAC) clocks on Renesas R-Car V3U
  - Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs
  - Allwinner H616 SoC clk support
