Date: Fri, 18 Nov 2016 17:20:42 -0600 From: Benoit Parrot <bparrot@...com> To: <linux-media@...r.kernel.org>, Hans Verkuil <hverkuil@...all.nl> CC: <linux-kernel@...r.kernel.org>, Tomi Valkeinen <tomi.valkeinen@...com>, Jyri Sarha <jsarha@...com>, Peter Ujfalusi <peter.ujfalusi@...com>, Benoit Parrot <bparrot@...com> Subject: [Patch v2 32/35] media: ti-vpe: vpdma: Add RAW8 and RAW16 data types Add RAW8 and RAW16 data type to VPDMA. To handle RAW format we are re-using the YUV CBY422 vpdma data type so that we use the vpdma to re-order the incoming bytes, as the VIP parser assumes that the first byte presented on the bus is the MSB of a 2 bytes value. RAW8 handles from 1 to 8 bits. RAW16 handles from 9 to 16 bits.
