Sounds like you should just implement runtime PM calls in the driver and let the lower level code take care of this for you along with the clocks etc. > @@ -1071,6 +1077,8 @@ static int c_can_open(struct net_device *dev) > struct c_can_priv *priv = netdev_priv(dev); > > c_can_pm_runtime_get_sync(priv); > + /* Initialize DCAN RAM */ > + c_can_reset_ram(priv, true); > > /* open the can device */ > err = open_candev(dev); > @@ -1099,6 +1107,8 @@ static int c_can_open(struct net_device *dev) > exit_irq_fail: > close_candev(dev); > exit_open_fail: > + /* De-Initialize DCAN RAM */ > + c_can_reset_ram(priv, false); > c_can_pm_runtime_put_sync(priv); > return err; > } Oh your already have pm_runtime here, OK so yeah let's let the omap/am33xx hwmod code do this for you. No changes to this driver needed then?
