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)...
