[PATCH v1 4/6] [media] ov9650: use write_array() for resolution sequences

Align resolution sequences on initialization sequence using i2c_rv structure NULL terminated .This add flexibility on resolution sequence size. Document resolution related registers by using corresponding define instead of hexa address/value. Signed-off-by: Hugues Fruchet

[PATCH v1 0/6] Add support of OV9655 camera

This patchset enables OV9655 camera support. OV9655 support has been tested using STM32F4DIS-CAM extension board plugged on connector P1 of STM32F746G-DISCO board. Due to lack of OV9650/52 hardware support, the modified related code could not have been checked for non-regression. First patches

[PATCH v1 6/6] [media] ov9650: add support of OV9655 variant

Add a first support of OV9655 variant. Because of register set slightly different from OV9650/9652, not all of the driver features are supported (controls). Supported resolutions are limited to VGA, QVGA, QQVGA. Supported format is limited to RGB565. Controls are limited to color bar test pattern
