2025-11-04net: stmmac: imx: convert to PHY_INTF_SEL_xxxRussell King (Oracle)
Convert dwmac-imx to use the PHY_INTF_SEL_xxx definitions rather than constants via: - ensuring that the prefix for the MASK and value definitions is the same. - using FIELD_PREP() to shift the PHY_INTF_SEL_xxx definition to the appropriate bitfield.

2025-11-04net: stmmac: add support for configuring the phy_intf_sel inputsRussell King (Oracle)
When dwmac is synthesised with support for multiple PHY interfaces, the core provides phy_intf_sel inputs, sampled on reset, to configure the PHY facing interface. Use stmmac_get_phy_intf_sel() in core code to determine the dwmac phy_intf_sel input value, and provide a new platform method called with this value just before we issue a soft reset to the dwmac core.

2025-11-04net: stmmac: add stmmac_get_phy_intf_sel()Russell King (Oracle)
Provide a function to translate the PHY interface mode to the phy_intf_sel pin configuration for dwmac1000 and dwmac4 cores that support multiple interfaces. We currently handle MII, GMII, RGMII, SGMII, RMII and REVMII, but not TBI, RTBI nor SMII as drivers do not appear to use these three and the driver doesn't currently support these.

commit 978fa2f6d0b12 ("drm/amd/display: Use scaling for non-native resolutions on eDP") started using the GPU scaler hardware to scale when a non-native resolution was picked on eDP. This scaling was done to fill the screen instead of maintain aspect ratio. The idea was supposed to be that if a different scaling behavior is preferred then the compositor would request it. The not following aspect ratio behavior however isn't desirable, so adjust it to follow aspect ratio and still try to fill screen. Note: This will lead to black bars in some cases for non-native resolutions. Compositors can request the previous behavior if desired.
