From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ramesh Shanmugasundaram Subject: [PATCH 3/5] media: Add new SDR formats SC16, SC18 & SC20 Date: Wed, 9 Nov 2016 15:44:42 +0000 Message-ID: <1478706284-59134-4-git-send-email-ramesh.shanmugasundaram@bp.renesas.com> References: <1478706284-59134-1-git-send-email-ramesh.shanmugasundaram@bp.renesas.com> Return-path: In-Reply-To: <1478706284-59134-1-git-send-email-ramesh.shanmugasundaram@bp.renesas.com> Sender: linux-media-owner@vger.kernel.org To: robh+dt@kernel.org, mark.rutland@arm.com, mchehab@kernel.org, hverkuil@xs4all.nl, sakari.ailus@linux.intel.com, crope@iki.fi Cc: chris.paterson2@renesas.com, laurent.pinchart@ideasonboard.com, geert+renesas@glider.be, linux-media@vger.kernel.org, devicetree@vger.kernel.org, linux-renesas-soc@vger.kernel.org, Ramesh Shanmugasundaram List-Id: devicetree@vger.kernel.org This patch adds support for the three new SDR formats. These formats were prefixed with "sliced" indicating I data constitutes the top half and Q data constitutes the bottom half of the received buffer. V4L2_SDR_FMT_SCU16BE - 14-bit complex (I & Q) unsigned big-endian sample inside 16-bit. V4L2 FourCC: SC16 V4L2_SDR_FMT_SCU18BE - 16-bit complex (I & Q) unsigned big-endian sample inside 18-bit. V4L2 FourCC: SC18 V4L2_SDR_FMT_SCU20BE - 18-bit complex (I & Q) unsigned big-endian sample inside 20-bit.
