[v5] clk: sunxi-ng: Consider alternative parent rates when determining NKM clock rate

[PATCH v5 03/11] clk: sunxi-ng: a64: allow pll-mipi to set parent's rate

Posted by Frank Oltmanns 2 years, 1 month ago

The nkm clock now supports setting the parent's rate. Utilize this
option to find the optimal rate for pll-mipi.
