2013-06-17[media] mt9p031: Use bulk regulator APILaurent Pinchart
The sensor is powered by three supplies. Use the bulk regulator API to enable and disable them instead of performing the operations manually. This fixes a warning caused by ignoring the return value of regulator_enable().

2013-05-21[media] mt9p031: Power down the sensor if no supported device has been detectedGuennadi Liakhovetski
The mt9p031 driver first accesses the I2C device in its .registered() method. While doing that it first powers the device up, but if probing fails, it doesn't power the chip back down. This patch fixes that bug.

2013-04-14[media] mt9p031: Add support for regulatorsLaurent Pinchart
Enable the regulators when powering the sensor up, and disable them when powering it down. The regulators are mandatory. Boards that don't allow controlling the sensor power lines must provide fixed voltage regulators.
