5d0eb375e6 clk: rockchip: Add clock controller driver for RK3528 SoC 
Add clock tree definition for RK3528. Similar to previous Rockchip
SoCs, clock controller of RK3528 is combined with the reset controller.
We omit the reset part for now since it's hard to test it without
support for other basic peripherals.

cc40f5baa9 clk: rockchip: Add clock controller for the RK3576 
Add the clock and reset tree definitions for the new RK3576
SoC.

As opposed to the other rockchip CRU drivers, the GRF node is looked up
via compatible instead of a phandle, which simplifies the device tree
bindings.

2408ab5aa8 clk: rockchip: Add clock controller support for RV1126 SoC 
Clock & Reset Unit (CRU) in RV1126 support clocks for CRU
and CRU_PMU blocks.

This patch is trying to add minimal Clock-Architecture Diagram's
inferred from [1] authored by Finley Xiao.

9af0cbeb47 clk: rockchip: drop module parts from rk3399 and rk3568 drivers 
Both of these drivers were converted to real drivers and got a tristate
build option. But them being builtin_platform_drivers, they only ever
should be build-in - as the name suggests.

So adapt the Kconfig symbol and drop the MODULE_* parts from the drivers.

e8c51b90f2 clk: rockchip: drop parenthesis from ARM || COMPILE_TEST depends 
As suggested by Stephen in the series adding the rk3568 clock controller
the depends works just as well without the parenthesis around the depends.

So to make everything look the same, drop them from existing entries too.
