[PATCH v2 7/8] arm64: dts: qcom: sm8150-hdk: fix FSA4480 address

From: Dmitry Baryshkov

Date: Mon Oct 19 2026 - 07:29:13 EST


The FSA4480 on the SM8150 HDK responds at 0x43 rather than 0x42. With
the wrong address the mux driver fails to probe, the Type-C controller
and the DisplayPort controller keep waiting for it and the display
subsystem never binds.

Fixes: ba712fd55c7b ("arm64: dts: qcom: sm8150-hdk: enable DisplayPort and USB-C altmode")
