Merge tag 'v6.1-rockchip-clock1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-rockchip

Pull Rockchip clk driver updates from Heiko Stuebner:

 - mux-variant clock using the table variant to select parents
 - clock controller for the rv1126 soc
 - conversion of rk3128 to yaml and relicensing of the yaml bindings
   to gpl2+MIT (following dt-binding guildelines)

* Rockchip RK3126/RK3128 Clock and Reset Unit
The RK3126/RK3128 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
Required Properties:
- compatible: should be "rockchip,rk3126-cru" or "rockchip,rk3128-cru"
"rockchip,rk3126-cru" - controller compatible with RK3126 SoC.
"rockchip,rk3128-cru" - controller compatible with RK3128 SoC.
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- #reset-cells: should be 1.
Optional Properties:
- rockchip,grf: phandle to the syscon managing the "general register files"
If missing pll rates are not changeable, due to the missing pll lock status.
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. All available clocks are defined as
preprocessor macros in the dt-bindings/clock/rk3128-cru.h headers and can be
used in device tree sources. Similar macros exist for the reset sources in
these files.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xin24m" - crystal input - required,
- "ext_i2s" - external I2S clock - optional,
- "gmac_clkin" - external GMAC clock - optional
Example: Clock controller node:
cru: cru@20000000 {
compatible = "rockchip,rk3128-cru";
reg = <0x20000000 0x1000>;
rockchip,grf = <&grf>;
#clock-cells = <1>;
#reset-cells = <1>;
};
Example: UART controller node that consumes the clock generated by the clock
controller:
uart2: serial@20068000 {
compatible = "rockchip,serial";
reg = <0x20068000 0x100>;
interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;
clock-frequency = <24000000>;
clocks = <&cru SCLK_UART2>, <&cru PCLK_UART2>;
clock-names = "sclk_uart", "pclk_uart";
};
