[PATCH 2/3] clk: qcom: dispcc-sc7280: Add dispcc resets
From: Bjorn Andersson
Date: Mon Aug 11 2025 - 23:12:54 EST
Like many other platforms the sc7280 display clock controller provides
a couple of resets for the display subsystem. In particular the
MDSS_CORE_BCR is useful to reset the display subsystem to a known state
during boot, so add these.
