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 Link on v1: https://lkml.org/lkml/2016/7/22/240 Grygorii Strashko (4): net: ethernet: ti: cpdma: fix lockup in cpdma_ctlr_destroy() drivers: net: cpsw: fix wrong regs access in cpsw_remove drivers: net: cpsw: use of_platform_depopulate() ARM: OMAP2+: omap_device: fix crash on omap_device removal arch/arm/mach-omap2/omap_device.c | 2 +- drivers/net/ethernet/ti/cpsw.c | 19 +++++++++---------- drivers/net/ethernet/ti/davinci_cpdma.c | 3 --- 3 files changed, 10 insertions(+), 14 deletions(-) -- 2.9.2
