Subject: [5/5] MIPS: Malta: support powering down
|
|
Origin: https://git.kernel.org/linus/dadaa1c2c0eddc09d11d7494b040c3f331ecd98f
|
|
|
|
This patch powers down the Malta in response to a power off command (eg.
|
|
poweroff or shutdown -P). It may then be powered back up by pressing the
|
|
"ON/NMI" button (S4) on the board. In cases where the power off state
|
|
cannot be entered (eg. because the required PCI support is disabled) the
|
|
current reset behaviour will be used as a fallback.
