This patch series adds support for custom type flags passed from
firmware. It also update fraction clock check from custom type
flags since new firmware pass CLK_FRAC flag as a part of custom flags
instead of clkflags as CLK_FRAC is not common clock framework flag.
This patch series maintains backward compatibility with older version
of firmware.
v2:
-PATCH[2/2] Correct BIT index of CLK_FRAC in custom_type_flag
Resend v2:
-We have tried to ping Stephen several times over email. Link:
https://lore.kernel.org/lkml/[email protected]/
and also we tried to pinged him over IRC this week without no reaction
that's why we are sending that patches again
