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.
Fixes: 0deb2624e2d0 ("arm64: dts: qcom: sa8155p-adp: Add support for uSD card")
