Instead use get_features to fix up Phy PMA capabilities for AQR111, AQR111B0, AQR114C and AQCS109 Fixes: 038ba1dc4e54 ("net: phy: aquantia: add AQR111 and AQR111B0 PHY ID") Fixes: 0974f1f03b07 ("net: phy: aquantia: remove false 5G and 10G speed abi= lity for AQCS109") Fixes: c278ec644377 ("net: phy: aquantia: add support for AQR114C PHY ID") Link: https://lore.kernel.org/all/20240913011635.1286027-1-quic_abchauha@qu= icinc.com/T/ Signed-off-by: Abhishek Chauhan --- Changes since v5 1. Minor comments addressed to not exceed 80 columns.=20 Changes since v4 1. Forget about asking hardware for PMA capabilites. 2. Just set the Gbits features along with 2.5Gbps support=20 for AQCS109 Phy chip.=20 3. Just set the Gbits features along with 5Gbps support=20 for AQR111, AQR111B0 and AQR114C Phy chips.=20 4. re-use aqr115c_get_features inside aqr111_get_features for further optimizations. Changes since v3 1. remove setting of 2500baseX bit introduced as part of previous patches. 2. follow reverse xmas declaration of variables. 3. remove local mask introduced as part of previous patch and optimize the logic. Changes since v2 1. seperate out the changes into two different patches.=20 2. use phy_gbit_features instead of initializing each and=20 every link mode bits.=20 3. write seperate functions for 2.5Gbps supported phy.=20 4. remove FIBRE bit which was introduced in patch 1. Changes since v1=20 1. remove usage of phy_set_max_speed in the aquantia driver code. 2. Introduce aqr_custom_get_feature which checks for the phy id and takes necessary actions based on max_speed supported by the phy. 3. remove aqr111_config_init as it is just a wrapper function. drivers/net/phy/aquantia/aquantia_main.c | 37 ++++++++++++------------ 1 file changed, 19 insertions(+), 18 deletions(-) diff --git a/drivers/net/phy/aquantia/aquantia_main.c b/drivers/net/phy/aqu= antia/aquantia_main.c index 86bb3b5bfc70..819d87b280ac 100644 --- a/drivers/net/phy/aquantia/aquantia_main.c +++ b/drivers/net/phy/aquantia/aquantia_main.c @@ -527,12 +527,6 @@ static int aqcs109_config_init(struct phy_device *phyd= ev) if (!ret) aqr107_chip_info(phydev); =20 - /* AQCS109 belongs to a chip family partially supporting 10G and 5G. - * PMA speed ability bits are the same for all members of the family, - * AQCS109 however supports speeds up to 2.5G only. - */ - phy_set_max_speed(phydev, SPEED_2500); - return aqr107_set_downshift(phydev, MDIO_AN_VEND_PROV_DOWNSHIFT_DFLT); } =20 @@ -734,6 +728,18 @@ static int aqr115c_get_features(struct phy_device *phy= dev) return 0; } =20 +static int aqr111_get_features(struct phy_device *phydev) +{ + /* PHY supports speeds up to 5G with autoneg.
