Patch 1 removes the clocking configuration from mtk_eth_soc for non- TRGMII, non-serdes based interface modes, and disables those interface modes prior to phylink configuration. Patch 2 removes the mac_pcs_get_state() method from mtk_eth_soc which I believe is also not used - mtk_eth_soc appears not to be used with SFPs (which would use a kind of in-band mode) nor does any DT appear to specify in-band mode for any non-serdes based interface mode. With both of those dealt with, the kernel is now free of any driver relying on the phylink legacy mode. Therefore, patch 3 removes support for this. Finally, with the advent of a new driver being submitted today that makes use of state->speed in the mac_config() path, patch 4 ensures that any phylink_link_state member that should not be used in mac_config is either cleared or set to an invalid value. v2: rebase on net-next, add attributations for testing etc drivers/net/ethernet/mediatek/mtk_eth_soc.c | 94 +++++------------------------ drivers/net/ethernet/mediatek/mtk_eth_soc.h | 1 + drivers/net/phy/phylink.c | 48 ++++++--------- include/linux/phylink.h | 45 ++------------ 4 files changed, 42 insertions(+), 146 deletions(-)
