Merge tag 'v5.13-rockchip-clocks' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-rockchip

Pull Rockchip clk driver updates from Heiko Stuebner:

 - Support for the clock controller on the new rk3568
 - Some cleanups for rk3399 modularization

* tag 'v5.13-rockchip-clocks' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  clk: rockchip: drop MODULE_ALIAS from rk3399 clock controller
  clk: rockchip: drop parenthesis from ARM || COMPILE_TEST depends
  clk: rockchip: add clock controller for rk3568
  clk: rockchip: support more core div setting
  dt-binding: clock: Document rockchip, rk3568-cru bindings
  clk: rockchip: add dt-binding header for rk3568

title: ROCKCHIP rk3568 Family Clock Control Module Binding

description: |
The RK3568 clock controller generates the clock and also implements a
reset controller for SoC peripherals.
(examples: provide SCLK_UART1\PCLK_UART1 and SRST_P_UART1\SRST_S_UART1 for UART module)
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/rk3568-cru.h headers and can be
used in device tree sources.
