ac4aa9db - phy: add driver for MediaTek XFI T-PHY

Tue, 09 Apr 2024 02:24:12 +0000

phy: add driver for MediaTek XFI T-PHYAdd driver for MediaTek's XFI T-PHY which can be found in the MT7988SoC. The XFI T-PHY is a 10 Gigabit/s Ethernet SerDes PHY with muxes onthe internal side to be used with either USXGMII PCS or LynxI PCS,depending on the selected PHY interface mode.The PHY can operates only in PHY_MODE_ETHERNET, the submode is one ofPHY_INTERFACE_MODE_* corresponding to the supported modes: * USXGMII \ * 10GBase-R }- USXGMII PCS - XGDM \ * 5GBase-R / \ }- Ethernet MAC * 2500Base-X \ / * 1000Base-X }- LynxI PCS - GDM / * Cisco SGMII (MAC side) /I chose the name XFI T-PHY because names of functions dealing with thephy in the vendor driver are prefixed "xfi_pextp_".The register space used by the phy is called "pextp" in the vendorsources, which could be read as "_P_CI _ex_press _T_-_P_hy", and thatis quite misleading as this phy isn't used for anything related toPCIe, so I wanted to find a better name.XFI is still somehow related (as in: you would find the relevantplaces using grep in the vendor driver when looking for that) and theterm seemed to at least somehow be aligned with the function of thatphy: Dealing with (up to) 10 Gbit/s Ethernet serialized differentialsignals.In order to work-around a performance issue present on the first oftwo XFI T-PHYs found in MT7988, special tuning is applied which canbe selected by adding the 'mediatek,usxgmii-performance-errata'property to the device tree node, similar to how the vendor driver isdoing that too.There is no documentation for most registers used for theanalog/tuning part, however, most of the registers have been partiallyreverse-engineered from MediaTek's SDK implementation (see links, anopaque sequence of 32-bit register writes) and descriptions for allrelevant digital registers and bits such as resets and muxes have beensupplied by MediaTek.Link: https://git01.mediatek.com/plugins/gitiles/openwrt/feeds/mtk-openwrt-feeds/+/b72d6cba92bf9e29fb035c03052fa1e86664a25b/21.02/files/target/linux/mediatek/files-5.4/drivers/net/ethernet/mediatek/mtk_sgmii.cLink: https://git01.mediatek.com/plugins/gitiles/openwrt/feeds/mtk-openwrt-feeds/+/dec96a1d9b82cdcda4a56453fd0b453d4cab4b85/21.02/files/target/linux/mediatek/files-5.4/drivers/net/ethernet/mediatek/mtk_eth_soc.cSigned-off-by: Daniel Golle Reviewed-by: AngeloGioacchino Del Regno Reviewed-by: Jacob Keller Link: https://lore.kernel.org/r/8719c82634df7e8e984f1a608be3ba2f2d494fb4.1712625857.git.daniel@makrotopia.orgSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/mediatek/Kconfig

phy: phy-mtk-dp: Add driver for DP phyThis is a new driver that supports the integrated DisplayPort phy formediatek SoCs, especially the mt8195. The phy is integrated into theDisplayPort controller and will be created by the mtk-dp driver. Thisdriver expects a struct regmap to be able to work on the same registersas the DisplayPort controller. It sets the device data to be the structphy so that the DisplayPort controller can easily work with it.The driver does not have any devicetree bindings because the datasheetdoes not list the controller and the phy as distinct units.The interaction with the controller can be covered by the configurecallback of the phy framework and its displayport parameters.Signed-off-by: Markus Schneider-Pargmann Signed-off-by: Guillaume Ranquet [Bo-Chen: Modify reviewers' comments.]Signed-off-by: Bo-Chen Chen Reviewed-by: AngeloGioacchino Del Regno Link: https://lore.kernel.org/r/20220624062725.4095-1-rex-bc.chen@mediatek.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/mediatek/Kconfig
