[PATCH 1/3] OMAP3: ISP: Add regulator control for omap34xx

[Laurent Pinchart]

From: Kalle Jokiniemi <kalle.jokiniemi@nokia.com>

The current omap3isp driver is missing regulator handling
for CSIb complex in omap34xx based devices. This patch
adds a mechanism for this to the omap3isp driver.

[PATCH 2/3] OMAP3: RX-51: define vdds_csib regulator supply

[Laurent Pinchart]

From: Kalle Jokiniemi <kalle.jokiniemi@nokia.com>

The RX-51 uses the CSIb IO complex for camera operation. The
board file is missing definition for the regulator supplying
the CSIb complex, so this is added for better power
management.

Tony, can I push this patch through the V4L/DVB tree, or would you like to
pick it yourself ?
