Subject: arm64: dts: rockchip: disable UHS modes for NanoPi R4S
|
|
|
|
The NanoPi R4S leaves the SD card in 1.8V signalling when rebooting
|
|
while U-Boot requires the card to be in 3.3V mode.
|
|
|
|
Remove UHS support from the SD controller so the card remains in 3.3V
|
|
mode. This reduces transfer speeds but ensures a reboot whether from
|
|
userspace or following a kernel panic is always working.
