> 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 for test purpose.

i2c device ids should be lower case to match compatible-strings in DT for
automatic modprobing.

Please pick/merge/copy&paste

i2c device ids should be lower case to match compatible-strings in DT for
automatic modprobing.

i2c device ids should be lower case to match compatible-strings in DT for
automatic modprobing.

Please pick/merge/copy&paste
