Signed-off-by: Sebastian Hesselbarth --- @Sascha: I forgot to update MVEBU SPI v4 patch numbering to indicate that this patch is also required for the SPI driver to find its clock with clk_get instead of clk_fixup. As stated in the original patch for SPI clock aliases, I am not planing to add any more clk aliases like this but prefer to work on DT clk provider first.
