Subject: [PATCH 106/182] clk: qcom: Properly support display clocks on
|
|
msm8974
|
|
|
|
The display clocks all source from dedicated phy PLLs within their
|
|
respective multimedia hardware block. Hook up these PLLs to the
|
|
display clocks with the appropriate parent mappings, clock flags,
|
|
and the appropriate clock ops. This should allow the display
|
|
clocks to work once the appropriate phy PLL driver registers their
|
|
PLL clocks.
