[PATCH can-next v2 0/3] can: tcan4x5x/m_can: use standby mode when down and in suspend

Posted by Sean Nyekjaer 1 week ago

When downing the tcan4x5x there is no reason to keep the tcan4x5x in
"normal" mode and waste power.
So set standby mode when the interface is down and normal mode when
interface is up.

Also when going into suspend, set the tcan4x5x into standby mode. The
tcan4x5x can still be used as a wake-source when in standby as low power
rx is enabled.
