+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).
