Subject: Re: [PATCH v2] [media] Add RGB444_1X12 and RGB565_1X16 media bus
 formats

Hello Mauro,

Last week I received a notification informing me that this patch was
"Not Applicable".
Could you give more details on why you think this should not go through
the media-tree (or am I misunderstanding the meaning of "Not
Applicable") ?

I really need this patch for the atmel HLCDC DRM driver, moreover this
patch from Philip [1] depends on mine.

Regards,

Boris
