Only the "SCLK rate bump" patch isn't strictly needed. Splitting this series won't cause building failures, but all pieces should be in place for the working driver. So I suppose it is okay if clk patches would get in earlier than the others, I'll split the series. Thank you for the review. -- Dmitry
