This is very confusing and suggests you write binding for the driver, which is not what we want. What's more, I really do not see the dependency here, so your message is incorrect? > > .../bindings/rtc/sophgo,cv1800-rtc.yaml | 40 +++++++++++++++++++ > 1 file changed, 40 insertions(+) > create mode 100644 Documentation/devicetree/bindings/rtc/sophgo,cv1800-rtc.yaml > You have dependencies between patches, but I do not see this explained at all.
