[PATCH v4 0/6] drm/rockchip: hdmi support for rk3328

The rk3228/rk3229 and rk3328 socs started using a new type of hdmi-phy
from Innosilicon that resides completely separate from the dw-hdmi block
and gets accessed via mmio.

Additionally the rk3328 dw-hdmi does not report the vendor-phy type
but a different one instead, so add the possibility to override the
phy type when the glue driver knows better than the ip block itself.

changes in v4:
- rebased onto 4.19-rc2 - no actual changes
- added Rob's Ack on the dw-hdmi compatible

changes in v3:
- split off phy driver into a separate series
- only allow forcing vendor phy type
- wording fixes and other nits

changes in v2:
- phy: prevent overflow in tmdsclk calculation
  as reported by Martin Cerveny
- phy: use unsigned long for all tmdsclk rate uses
- phy: simplify tmds rate calculation
- dropped patch exporting some dw-hdmi phy functions
  as a similar patch entered drm-misc already

Heiko Stuebner (6):
  drm/bridge: dw-hdmi: allow forcing vendor phy-type
  drm/rockchip: dw_hdmi: Allow outputs that don't need output switching
  dt-bindings: allow optional phys in Rockchip dw_hdmi binding
  drm/rockchip: dw_hdmi: allow including external phys
  drm/rockchip: dw_hdmi: store rockchip_hdmi reference in phy_data
    object
  drm/rockchip: dw_hdmi: add dw-hdmi support for the rk3328
