Subject: [PATCH v5 net-next 0/5] net: ethernet: mtk_wed: introduce reset support
Introduce proper reset integration between ethernet and wlan drivers in order
to schedule wlan driver reset when ethernet/wed driver is resetting.
Introduce mtk_hw_reset_monitor work in order to detect possible DMA hangs.
Changes since v4:
- add missing usleep_range
Changes since v3:
- rely on msleep() utility instead of mdelay() in mtk_hw_init() and
usleep_range() in mtk_ppe_prepare_reset() since the code runs in
non-atomic context
Changes since v2:
- rebase on top of net-next
- move rtnl_lock/rtnl_unlock in reset callback
- re-run mtk_prepare_for_reset() after mtk_wed_fe_reset() acquiring RTNL lock
Changes since v1:
- rebase on top of net-next
