Subject: [PATCH] reboot: Use power off rather than busy spinning when
|
|
halt is requested
|
|
|
|
Busy spinning after halt is dumb
|
|
We've previously applied this patch to arch/arm
|
|
but it is currenltly missing in arch/arm64
|
|
|
|
Pi4 after "sudo halt" uses 520mA
|
|
Pi4 after "sudo shutdown now" uses 310mA
|
|
|
|
Make them both use the lower powered option
