Subject: [PATCH] arm64: dts: rockchip: regulator for sd needs to be always on
|
||
|
|
for BPI-R2Pro
|
||
|
|
|
||
|
|
With default dts configuration for BPI-R2Pro, the regulator for sd card is
|
||
|
|
powered off when reboot is commanded, and the only solution to detect the
|
||
|
|
sd card again, and therefore, allow rebooting from there, is to do a
|
||
|
|
hardware reset.
|
||
|
|
|
||
|
|
Configure the regulator for sd to be always on for BPI-R2Pro in order to
|
||
|
|
avoid this issue.
|
||
