drm_gralloc invalid argument error (-22) during camera HAL3 preview

Hi,

(Sorry I have some issue on using group and keep write and delete the same post, this time I won't.)

I'm trying to enable HAL3 ref code located on /hardware/libhardware/modules/camera to see the code flow of new camera SW.
After I fixed some crashes on HAL3 code, it shows below errors from drm_gralloc.

Looks like drm_gralloc is complaining about the format 0x22 for the dequeue request from camera3-outputstream.
Does drm_gralloc support below format ?

- CAMERA2_HAL_PIXEL_FORMAT_OPAQUE (0x22, identical to HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED)

Thanks,

I guess not. Patches are welcome.
