i.MX6Q V4L2 IOCT- IPU_ROTATE_HORIZ_FLIP can't work

[xiaoqianlin]

Hi,

Cloudtech reported i.MX6Q V4L2 IOCT- IPU_ROTATE_HORIZ_FLIP  can't work. Can you help to check?

imx6q  android 4.2.2平台上用adv7180  camera 由于拍照方向水平镜像了需要用到ipu 来实现 H mirror, 通过
V4L2  IOCTL 调用但目前case V4L2_CID_MXC_ROT:中的IPU_ROTATE_HORIZ_FLIP 不起作用，但IPU_ROTATE_VERT_FLIP这个垂直镜像可以。

Hi Linda, for IPU display channel, it can only support IPU_ROTATE_VERT_FLIP(vertical filp), for other kind of rotation, the customer should use IPU task to implement it.

Thank you, Quiang Li!

Only one FLIP can work at the same time, so IPU_ROTATE_HORIZ_FLIP + IPU_ROTATE_VERT_FLIP can't work.
