From 819fe8c96a5172dfd960e5945e8f00f8fed32953 Mon Sep 17 00:00:00 2001 From: Volodymyr Babchuk Volodymyr_Babchuk@epam.com Date: Fri, 12 Apr 2024 19:03:25 +0000 Subject: [PATCH] arm64: dts: qcom: sa8155p-adp: fix SDHC2 CD pin configuration

There are two issues with SDHC2 configuration for SA8155P-ADP, which prevent use of SDHC2 and causes issues with ethernet:

- Card Detect pin for SHDC2 on SA8155P-ADP is connected to gpio4 of PMM8155AU_1, not to SoC itself. SoC's gpio4 is used for DWMAC TX. If sdhc driver probes after dwmac driver, it reconfigures gpio4 and this breaks Ethernet MAC.

- pinctrl configuration mentions gpio96 as CD pin. It seems it was copied from some SM8150 example, because as mentioned above, correct CD pin is gpio4 on PMM8155AU_1.

This patch fixes both mentioned issues by providing correct pin handle and pinctrl configuration.
