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!
