[PATCH 6/7] arm64: dts: qcom: sm8750: Correct and complete DP address spaces

From: Krzysztof Kozlowski

Date: Thu Apr 02 2026 - 07:56:02 EST


DisplayPort block on Qualcomm SM8750 has few too short address space
ranges and misses four more spaces. Complete the hardware description,
which in the future might be important for full feature support.
