IMX6 Overlay resolution set

[anjojohn]

Hi all,

how to set the overlay resolution /dev/fb1 to a default value. Currently it is showing as 320x240. saw the dummy values set in linux-imx6/mxc_ipuv3_fb.c at boundary-imx_3.14.28_1.0.0_ga · boundarydevices/linux-imx6 · GitHub . Changed this to 1600x900 , but its coming as 1280x720. I tested with "fbset -xres 1600 -yres 900 -fb /dev/fb1" and is working. But fbset does'n make any change if i call this from init-script. Is there a way to hard-code the resolution, or any IOCTL call toset the overlay resolution

one can try to use the FBIOPUET_VSCREENINFO, for more detailed information, pls refer to the link as below:

focus on the mxc_v4l2_tvin test source code.
