-Subject: [PATCH] net: stmmac: use suspend functions for hibernation
-
-In hibernation freeze case the driver just releases the resources like
-dma buffers, irqs, unregisters the drivers and during restore it does
-register, request the resources. This is not really necessary, as part
-of power management all the data structures are intact, all the
-previously allocated resources can be used after coming out of low
-power.
-
-This patch uses the suspend and resume callbacks for freeze and
-restore which initializes the hardware correctly without unregistering
-or releasing the resources, this should also help in reducing the time
-to restore.
-
-Also this patch fixes a bug in stmmac_pltfr_restore and
-stmmac_pltfr_freeze where it tries to get hold of platform data via
-dev_get_platdata call, which would return NULL in device tree cases and
-the next if statement would crash as there is no NULL check.
