Thank you for resolving this issue so quickly!

I've applied the patch locally and gone through the reproduction
steps. The kernel builds fine now.

[PATCH] drm: bridge: for GENERIC_PHY_MIPI_DPHY also select GENERIC_PHY

2023-08-03 Thread Randy Dunlap 
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.
