0cd9d14283 drm: bridge/dw_hdmi: add support for multi-byte register width access
On rockchip rk3288, only word(32-bit) accesses are
permitted for hdmi registers.  Byte width accesses (writeb,
readb) generate an imprecise external abort.

b21f4b658d drm: imx: imx-hdmi: move imx-hdmi to bridge/dw_hdmi
the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi

34ea3d3863 drm: add register and unregister functions for connectors
Introduce generic functions to register and unregister connectors. This
provides a common place to add and remove associated user space
interfaces.

f9b0e251df drm: make mode_valid callback optional
Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.

v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c

90bde571ad drm/bridge: PTN3460 needs DRM_KMS_HELPER
The recently added PTN3460 device driver uses interfaces that
are provided by the KMS helper infrastructure, so we should
explicitly select that to avoid this linker error:

ERROR: "drm_helper_probe_single_connector_modes" [drivers/gpu/drm/bridge/ptn3460.ko] undefined!
ERROR: "drm_helper_connector_dpms" [drivers/gpu/drm/bridge/ptn3460.ko] undefined!

We have to drop the I2C dependency to avoid a circular dependency
chain, but that's ok because DRM already selects I2C.
