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

From: Philippe Cornu
Date: Wed Apr 25 2018 - 03:54:08 EST

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
- 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
