From bc0c8804b54d3fa561e341292b566b9ffaae6e8c Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Wed, 11 Sep 2019 22:45:51 +0200 Subject: [PATCH 4/5] clk: rockchip: add video-related niu clocks as critical on px30 Video-In and -Out interconnect clocks need to stay on all the time for the peripheral to work and we do not model the actual interconnect at this point. So mark them as critical for now.
