From: Veerabhadrarao Badiganti <[email protected]> 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.
