Hi, thank you for review, v2 is about to be sent, here just let me anwer issue I didn't address there.

This is a bit problematic, comment above USBDRD_UCTL_CTL_REF_CLK_SEL says: /* Reference clock select for SuperSpeed and HighSpeed PLLs: * 0x0 = Both PLLs use DLMC_REF_CLK0 for reference clock * 0x1 = Both PLLs use DLMC_REF_CLK1 for reference clock * 0x2 = SuperSpeed PLL uses DLMC_REF_CLK0 for reference clock & * HighSpeed PLL uses PLL_REF_CLK for reference clck * 0x3 = SuperSpeed PLL uses DLMC_REF_CLK1 for reference clock & * HighSpeed PLL uses PLL_REF_CLK for reference clck */ So I really cannot imagine sane name. Also please note, that field and register names were created to match documentation. Values, however, have no defined names, so I would need to invent them. That is something I'd like to avoid as it might be confusing. And last, but to least: Octeon would deserve proper clock api (clk driver to be implemented). So hopefully that code get replaced with more sane one. For now, I just kept compatibility with current DT. Thanks, ladis
