title: Qualcomm Display Clock & Reset Controller Binding for SDM845
maintainers:
- Taniya Das <tdas@codeaurora.org>
description: |
Qualcomm display clock control module which supports the clocks, resets and
power domains on SDM845.
See also 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.
