[ Upstream commit 96413b355a49fd684430a230479bd231d977894f ]
Three DRM bridge drivers select GENERIC_PHY_MIPI_DPHY when GENERIC_PHY might not be set. This causes Kconfig warnings and a build error.
WARNING: unmet direct dependencies detected for GENERIC_PHY_MIPI_DPHY Depends on [n]: GENERIC_PHY [=n] Selected by [y]: - DRM_NWL_MIPI_DSI [=y] && DRM_BRIDGE [=y] && DRM [=y] && COMMON_CLK [=y] && OF [=y] && HAS_IOMEM [=y] - DRM_SAMSUNG_DSIM [=y] && DRM [=y] && DRM_BRIDGE [=y] && COMMON_CLK [=y] && OF [=y] && HAS_IOMEM [=y]
(drm/bridge/cadence/Kconfig was found by inspection.)
aarch64-linux-ld: drivers/gpu/drm/bridge/samsung-dsim.o: in function `samsung_dsim_set_phy_ctrl': drivers/gpu/drm/bridge/samsung-dsim.c:731: undefined reference to `phy_mipi_dphy_get_default_config_for_hsclk'
Prevent these warnings and build error by also selecting GENERIC_PHY whenever selecting GENERIC_PHY_MIPI_DPHY.
