[PATCH 0/9] arm64: qcom: enable display card support on SM8150 HDK
From: Dmitry Baryshkov
Date: Thu Oct 15 2026 - 05:10:13 EST
The Qualcomm SM8150 HDK can be equipped with an optional display card
having the same panel as the display card for SDM845 HDK. Reuse the
driver submitted at [1] and enable display card support on this HDK.
Unlike SDM845, this also requires a new LCDB driver, providing voltage
for the panel and several fixes in the WLED driver. The FSA4480 address
fix is independent and can be applied earlier.
