clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs

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

- 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
