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 upgrade current support of OV9650/52 to prepare then introduction of OV9655 variant patch. Because of OV9655 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. OV9655 initial support is based on a driver written by H. Nikolaus Schaller [1]. OV9655 registers sequences come from STM32CubeF7 embedded software [2].
