[PATCH v2 0/2] drm/bridge: sii902x: add optional power supplies

[Philippe Cornu]

This patchset adds optional power supplies to the sii902x
drm bridge driver.

Version 2:
- merge avcc12 & cvcc12 to a single vcc12 supply as suggested by
  Laurent Pinchart (see discussion details in
  https://patchwork.freedesktop.org/patch/216058/)
- improve error messages following Laurent Pinchart comments.
- note about power consumption: as sii902x input IOs are not "io safe",
  it is important to enable/disable voltage regulators during
  probe/remove phases to avoid damages. Then, the only way to improve
  the power consumption is to add the sii902x standy mode. My actual
  platform is not an handheld device so power consumption is not
  critical. But in the future, it could be nice to add the standby
  mode, paying attention to wake-up events (hdmi cable plug)...

Version 1:
- Initial commit
