[PATCH 3/3] arm64: dts: qcom: Add INT2_GDSC to MDSS on Kaanapali and Glymur
From: Yongxing Mou
Date: Mon Jul 20 2026 - 04:45:15 EST
Kaanapali (SM8750) and Glymur use two display power domains.
CORE_GDSC powers the main display hardware while INT2_GDSC powers
a subset of SSPP blocks (VIG2/VIG3/DMA5/DMA6).
Add DISP_CC_MDSS_CORE_INT2_GDSC alongside the existing CORE_GDSC
reference in the MDSS node on both platforms and provide matching
power-domain-names entries for the display power domains.
