[PATCH net-next v2 0/7] add enhancement into the existing reset flow
From: Sean Wang Current driver only resets DMA used by descriptor rings which can't guarantee it can recover all various kinds of fatal errors, so the patch 1) tries to reset the underlying hardware resource from scratch on Mediatek SoC required for ethernet running. 2) refactors code in order to the reusability of existing code. 3) considers handling for race condition between the reset flow and callbacks registered into core driver called about hardware accessing. 4) introduces power domain usage to hardware setup which leads to have cleanly and completely restore to the state as the initial. Changes since v1: - fix the build error with module built causing undefined symbol for pinctrl_bind_pins, so using pinctrl_select_state instead accomplishes the pin mux setup during the reset process. Sean Wang (7): net: ethernet: mediatek: refactoring mtk_hw_init to be reused net: ethernet: mediatek: add mtk_hw_deinit call as the opposite to mtk_hw_init call net: ethernet: mediatek: cleanup error path inside mtk_hw_init net: ethernet: mediatek: add controlling power domain the ethernet belongs to net: ethernet: mediatek: add the whole ethernet reset into the reset process net: ethernet: mediatek: add more resets for internal ethernet circuit block net: ethernet: mediatek: avoid race condition during the reset process drivers/net/ethernet/mediatek/mtk_eth_soc.c | 226 +--- drivers/net/ethernet/mediatek/mtk_eth_soc.h | 15 +- 2 files changed, 186 insertions(+), 55 deletions(-) -- 1.9.1
