The rationale is that thedriver has been already relying on the syscon functionality.Moreover, without MFD_SYSCON enabled, the test coverage is reduced,since the linker might not detect any potential undefined referencesfollowing syscon_regmap_lookup_by_phandle() invocation inrk_hdptx_phy_probe() body. That is because the function wouldunconditionally return -ENOTSUP, hence the compiler is free to optimizeout any unreachable code.Finally ensure PHY_ROCKCHIP_SAMSUNG_HDPTX depends on HAS_IOMEM, asrequired by MFD_SYSCON.Fixes: 553be2830c5f ("phy: rockchip: Add Samsung HDMI/eDP Combo PHY driver")Signed-off-by: Cristian Ciocaltea Link: https://lore.kernel.org/r/20240629-rk-hdptx-compile-test-fix-v1-1-c86675ba8070@collabora.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/rockchip/Kconfig

When parsing from DT,the property "rockchip,dp-lane-mux" provide the DP mux and mappinginfo. This is needed when the PHY is not used with TypeC Alt-Mode.For example if the USB3 interface of the PHY is connected to a USBType A connector and the DP interface is connected to a DisplayPortconnector.When do DP link training, need to set lane number, link rate, swing,and pre-emphasis via PHY configure interface.Co-developed-by: Heiko Stuebner Signed-off-by: Heiko Stuebner Co-developed-by: Zhang Yubing Signed-off-by: Zhang Yubing Co-developed-by: Frank Wang Signed-off-by: Frank Wang Signed-off-by: Sebastian Reichel Link: https://lore.kernel.org/r/20240408225109.128953-3-sebastian.reichel@collabora.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/rockchip/Kconfig
