From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jungo Lin Subject: [RFC,V2,07/11] media: platform: Add Mediatek ISP P1 private control Date: Fri, 10 May 2019 09:58:00 +0800 Message-ID: <20190510015755.51495-8-jungo.lin@mediatek.com> References: Reply-To: Jungo Lin Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: tfiga@chromium.org, hans.verkuil@cisco.com, laurent.pinchart+renesas@ideasonboard.com, matthias.bgg@gmail.com, mchehab@kernel.org Cc: shik@chromium.org, devicetree@vger.kernel.org, Sean.Cheng@mediatek.com, suleiman@chromium.org, Rynn.Wu@mediatek.com, srv_heupstream@mediatek.com, ryan.yu@mediatek.com, Jerry-ch.Chen@mediatek.com, frankie.chiu@mediatek.com, Jungo Lin , sj.huang@mediatek.com, yuzhao@chromium.org, linux-mediatek@lists.infradead.org, seraph.huang@mediatek.com, zwisler@chromium.org, christie.yu@mediatek.com, frederic.chen@mediatek.com, linux-arm-kernel@lists.infradead.org, linux-media@vger.kernel.org List-Id: devicetree@vger.kernel.org Reserved Mediatek ISP P1 private control number with 16. Moreover, add two private controls for ISP P1 user space usage. 1. V4L2_CID_PRIVATE_GET_BIN_INFO - Provide the image output width & height in case camera binning mode is enabled. 2. V4L2_CID_PRIVATE_RAW_PATH - Export the path control of the main stream to user space. One is pure raw and the other is processing raw. The default image path is pure raw.
