Subject: [PATCH] can: flexcan: add LPSR mode support for i.MX7D
|
|
|
|
For i.MX7D LPSR mode, the controller will lost power and got the
|
|
configuration state lost after system resume back.
|
|
So we need to set pinctrl state again and re-start chip to do
|
|
re-configuration after resume.
|
|
|
|
For wakeup case, it should not set pinctrl to sleep state by
|
|
pinctrl_pm_select_sleep_state.
|
|
For interface is not up before suspend case, we don't need
|
|
re-configure as it will be configured by user later by interface up.
