-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.
