[PATCH V2] arm64: dts: qcom: sc7180: SD-card GPIO pin set bias-pull up

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Veerabhadrarao Badiganti <vbadigan@xxxxxxxxxxxxxx>

On some sc7180 based platforms where external pull is not present on cd-gpio,
this gpio state is getting read as HIGH when sleep config is applied on it.
This is resulting in SDcard rescan after suspend-resume even though SDcard
is not present.

Update cd-gpio sleep config with bais-pull to fix this issue.
