Subject: RE: [PATCH v2] drm: drm_fourcc: adding 10/12/14 bit formats
Hi Ville, good morning.
I fixed my patch according to your comments and posted it for another review.
I didn't receive more comments from you.
Is it mean that it passed the review and can be merged?
Thank you
Yulia

Subject: [PATCH v2] drm: drm_fourcc: adding 10/12/14 bit formats
Adding the following formats
- DRM_FORMAT_RX106
- DRM_FORMAT_GXRX106106
- DRM_FORMAT_RX124
- DRM_FORMAT_GXRX124124
- DRM_FORMAT_AXBXGXRX124124124124
- DRM_FORMAT_RX142
- DRM_FORMAT_GXRX142142
- DRM_FORMAT_AXBXGXRX142142142142
They are useful for communicating Bayer data between ISPs and GPU by emulating GL_R16UI and GL_RG16UI formats
