Changes since v2:
- Bart's SOB goes first, as he is the original author.
- Add MFP_LPM_DRIVE_HIGH to camera gpios, as per Motorola original
code.
- s/pxacamera/camera/ in function names, as they are not used in
pxacamera_platform_data
- Adjust comments about CAM_RST which is active on rising edge
- Saner default values for nCAM_EN and CAM_RST gpios
- Setup gpios statically at board init.
Eric, if it is easier for you I can send the three patches together again.
Thanks,
Antonio
