From 5209e1b8f78fd1184f25cf19cf0daa58f4ad6599 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 1 Dec 2016 22:00:20 +0100 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).
