[PATCH] drm/i915: set minimum CD clock to twice the BCLK.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Abhay Kumar <abhay.kumar@xxxxxxxxx>

In glk when device boots with only 1366x768 panel, HDA codec doesn't comeup.
This result in no audio forever as cdclk is < 96Mhz.
This chagne will ensure CD clock to be twice of  BCLK.
