title: Qualcomm Display Clock & Reset Controller on SDM845

description: |
Qualcomm display clock control module provides the clocks, resets and power
domains on SDM845.
See also:: include/dt-bindings/clock/qcom,dispcc-sdm845.h
properties:
compatible:
const: qcom,sdm845-dispcc
# NOTE: sdm845.dtsi existed for quite some time and specified no clocks.
# The code had to use hardcoded mechanisms to find the input clocks.
# New dts files should have these clocks.
