linux_dsm_epyc7002/drivers/clk/sunxi-ng/ccu-sun50i-a64.c
Linus Torvalds 916f562fb2 This round of clk driver and framework updates is heavy on the driver update 
side. The two main highlights in the core framework are the addition of an bulk
 clk_get API that handles optional clks and an extra debugfs file that tells the
 developer about the current parent of a clk.
 
 The driver updates are dominated by i.MX in the diffstat, but that is mostly
 because that SoC has started converting to the clk_hw style of clk
 registration. The next big update is in the Amlogic meson clk driver that
 gained some support for audio, cpu, and temperature clks while fixing some PLL
 issues. Finally, the biggest thing that stands out is the conversion of a large
 part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
 less strings and more pointer comparisons to match clk parents and children up.
 
 In general, it looks like we have a lot of little fixes and tweaks here and
 there to clk data along with the normal addition of a handful of new drivers
 and a couple new core framework features.
 
 Core:
  - Add a 'clk_parent' file in clk debugfs
  - Add a clk_bulk_get_optional() API (with devm too)
 
 New Drivers:
  - Support gated clk controller on MIPS based BCM63XX SoCs
  - Support SiLabs Si5341 and Si5340 chips
  - Support for CPU clks on Raspberry Pi devices
  - Audsys clock driver for MediaTek MT8516 SoCs
 
 Updates:
  - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
  - Small frequency support for SiLabs Si544 chips
  - Slow clk support for AT91 SAM9X60 SoCs
  - Remove dead code in various clk drivers (-Wunused)
  - Support for Marvell 98DX1135 SoCs
  - Get duty cycle of generic pwm clks
  - Improvement in mmc phase calculation and cleanup of some rate defintions
  - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
  - Add GPIO, SNVS and GIC clocks for i.MX8 drivers
  - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
  - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
  - Add clks for new Exynos5422 Dynamic Memory Controller driver
  - Clock definition for Exynos4412 Mali
  - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
  - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
  - TI clock probing done from DT by default instead of firmware
  - Fix Amlogic Meson mpll fractional part and spread sprectrum issues
  - Add Amlogic meson8 audio clocks
  - Add Amlogic g12a temperature sensors clocks
  - Add Amlogic g12a and g12b cpu clocks
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
