[PATCH v3 1/3] dt-bindings: clock: qcom,eliza-dispcc: Add Eliza SoC display CC

From: Krzysztof Kozlowski

Date: Thu Mar 19 2026 - 07:52:59 EST

Add bindings for Qualcomm Eliza SoC display clock controller (dispcc),
which is very similar to one in SM8750, except new HDMI-related clocks
and additional clock input from HDMI PHY PLL.
