Hi Rob, Thanks for your review.

From this binding yes, but the idea is to add in the dt wherever clock responsible for the full ACLK path for instance. In the example below, clock aclk_isp is ACLK_ISP0_WRAPPER.

Or really since these are just different instances, just combine them into 1 conditional allowing 3 or 4 clocks. There are lots of examples to follow in the tree. Rob
Move the bindings out of drivers/staging and place them in Documentation/devicetree/bindings instead. Also, add DT nodes for RK3399 and verify with make ARCH=arm64 dtbs_check and make ARCH=arm64 dt_binding_check. Tested by verifying images streamed from Scarlet Chromebook Changes in v4: - simplify clocks with "isp", "aclk" and "hclk" as suggested by Robin Murphy on https://patchwork.kernel.org/patch/11475007/ Changes in v3: - dropped accepted patches - cleanup clocks - fix "no reg" error in dt-bindings parent@0 example - add linux-rockchip list in MAINTAINERS and reorder items - add Scarlet sensors dt nodes to the series Changes in v2: Add patches modifying bindings, as sugested by Johan Jonker in v1, before moving them out of staging.
