Subject: [PATCH] clk: bcm: Allow rate change propagation to PLLH_AUX on VEC
|
|
clock
|
|
|
|
The VEC clock requires needs to be set at exactly 108MHz. Allow rate
|
|
change propagation on PLLH_AUX to match this requirement wihtout
|
|
impacting other IPs (PLLH is currently only used by the HDMI encoder,
|
|
which cannot be enabled when the VEC encoder is enabled).
