Pull clk updates from Stephen Boyd:
"The core framework got some nice improvements this time around. We
gained the ability to get struct clk pointers from a struct clk_hw so
that clk providers can consume the clks they provide, if they need to
do something like that. This has been a long missing part of the clk
provider API that will help us move away from exposing a struct clk
pointer in the struct clk_hw. Tracepoints are added for the
clk_set_rate() "range" functions, similar to the tracepoints we
already have for clk_set_rate() and we added a column to debugfs to
help developers understand the hardware enable state of clks in case
firmware or bootloader state is different than what is expected.
Overall the core changes are mostly improving the clk driver writing
experience.
At the driver level, we have the usual collection of driver updates
and new drivers for new SoCs. This time around the Qualcomm folks
introduced a good handful of clk drivers for various parts of three or
four SoCs. The SiFive folks added a new clk driver for their FU740
SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
SoCs had lots of work done after that for various new features. One
last thing to note in the driver area is that the i.MX driver has
gained a new binding to support SCU clks after being on the list for
many months. It uses a two cell binding which is sort of rare in clk
DT bindings. Beyond that we have the usual set of driver fixes and
tweaks that come from more testing and finding out that some
configuration was wrong or that a driver could support being built as
a module.
Summary:
Core:
- Add some trace points for clk_set_rate() "range" functions
- Add hardware enable information to clk_summary debugfs
- Replace clk-provider.h with of_clk.h when possible
- Add devm variant of clk_notifier_register()
- Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
New Drivers:
- Bindings for Canaan K210 SoC clks
- Support for SiFive FU740 PRCI
- Camera clks on Qualcomm SC7180 SoCs
- GCC and RPMh clks on Qualcomm SDX55 SoCs
- RPMh clks on Qualcomm SM8350 SoCs
- LPASS clks on Qualcomm SM8250 SoCs
Updates:
- DVFS support for AT91 clk driver
- Update git repo branch for Renesas clock drivers
- Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
- Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
- Stop using __raw_*() I/O accessors in Renesas clk drivers
- One more conversion of DT bindings to json-schema
- Make i.MX clk-gate2 driver more flexible
- New two cell binding for i.MX SCU clks
- Drop of_match_ptr() in i.MX8 clk drivers
- Add arch dependencies for Rockchip clk drivers
- Fix i2s on Rockchip rk3066
- Add MIPI DSI clks on Amlogic axg and g12 SoCs
- Support modular builds of Amlogic clk drivers
- Fix an Amlogic Video PLL clock dependency
- Samsung Kconfig dependencies updates for better compile test coverage
- Refactoring of the Samsung PLL clocks driver
- Small Tegra driver cleanups
- Minor fixes to Ingenic and VC5 clk drivers
- Cleanup patches to remove unused variables and plug memory leaks"
