- 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).
