greybus: camera: Configure APB-A with new params
Update the configuration supplied to APB-A to use new parameters, while keeping compatibility with legacy camera modules. Substitute hard-coded clock frequency with information provided by camera module, and retrieve the maximum CSI Long Packet length from the returned stream configuration. This patch requires APB-A csi-tx driver to be updated to comply with newly defined bandwidth requirements. Testing Done: preview, capture and video recording with updated csi-tx driver on APB-A side, and legacy white camera module firmware Signed-off-by: Jacopo Mondi <jacopo.mondi@linaro.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
