Re: [PATCH v16 5/6] dt-bindings: clock: meson: add A1 Peripherals clock controller bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Rob, Krzysztof and Conor,

Could you please take a look at this patch version? Before Rob marked
this patchset with RvB at v13 -
https://lore.kernel.org/linux-amlogic/168130720431.2218249.7671061964988064525.robh@xxxxxxxxxx/

However, due to several comments from other maintainers, unfortunately,
I had to rename the 'a1-clkc' controller to 'a1-peripherals-clkc' and
remove Rob's RvB.

I would be grateful for your assistance!
