Hi,
I cannot merge this upstream as it was collectively
decided that there should be no new fbdev drivers
(DRM subsystem should be used instead).
[ You may consider submitting this driver to staging
subsystem to make hardware usable by kernel while
proper DRM driver is being developed. ]
Best regards,

Hi,
I cannot merge this upstream as it was collectively
decided that there should be no new fbdev drivers
(DRM subsystem should be used instead).
[ You may consider submitting this driver to staging
subsystem to make hardware usable by kernel while
proper DRM driver is being developed. ]
Best regards,
