Subject[PATCH v4 2/2] dt-bindings: clocks: rk3288: add rk3288w compatible
Date
Add the possible compatible "rockchip,rk3288w-cru" that handles
the difference between the rk3288 and the new revision rk3288w.

This compatible will be added by bootloaders.

@@ -4,9 +4,15 @@ The RK3288 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.

+A revision of this SoC is available: rk3288w. The clock tree is a bit
+different so another dt-compatible is available. Noticed that it is only
+setting the difference but there is no automatic revision detection. This
+should be performed by bootloaders.
+
Required Properties:

-- compatible: should be "rockchip,rk3288-cru"
+- compatible: should be "rockchip,rk3288-cru" or "rockchip,rk3288w-cru" in
+ case of this revision of Rockchip rk3288.
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
