Subject: [PATCH v2 0/4] drivers: net: cpsw: fix driver loading/unloading
Date: Thu, 28 Jul 2016 20:50:33 +0300 [thread overview]
Message-ID: <20160728175037.22053-1-grygorii.strashko@ti.com> (raw)
This series fixes set of isssues observed when CPSW driver module is unloaded/loaded:
1) rmmod: deadlock in cpdma_ctlr_destroy
2) rmmod: L3 back-trace and crash if all net interfaces are down, because CPSW
can be powerred down by PM runtime in this case.
3) insmod: mdio device is not recreated on next insmod
- need to use of_platform_depopulate() in cpsw_remove().
4) rmmod: system crash on omap_device removal
Tested on: am437x-idk, am57xx-beagle-x15
Changes in v2:
- build warning fixed
- added fix for correct omap_device removal
