From 9c7302f485c701900af7902af10d8a111e0a6192 Mon Sep 17 00:00:00 2001 From: Zefa Chen Date: Fri, 17 May 2019 18:23:03 +0800 Subject: [PATCH 0282/1085] media: i2c: add ov9281 driver. Change-Id: I7b77250bbc56d2f861450cf77271ad15f9b88ab1 Signed-off-by: Zefa Chen media: i2c: ov9281: fix mclk issue when probe multiple camera. Takes the ov9281 part only from the Rockchip's patch. Change-Id: I30e833baf2c1bb07d6d87ddb3b00759ab45a90e4 Signed-off-by: Zefa Chen media: i2c: ov9281: add enum_frame_interval function for iq tool 2.2 and hal3 Adds the ov9281 parts of the Rockchip patch adding enum_frame_interval to a large number of drivers. Change-Id: I03344cd6cf278dd7c18fce8e97479089ef185a5c Signed-off-by: Zefa Chen media: i2c: ov9281: Fixup for recent kernel releases, and remove custom code The Rockchip driver was based on a 4.4 kernel, and had several custom Rockchip parts. Update to 5.4 kernel APIs, with the relevant controls required by libcamera, and remove custom Rockchip parts. Signed-off-by: Dave Stevenson media: i2c: ov9281: Read chip ID via 2 reads Vision Components have made an OV9281 module which blocks reading back the majority of registers to comply with NDAs, and in doing so doesn't allow auto-increment register reading as used when reading the chip ID. Use two reads and manually combine the results. Signed-off-by: Dave Stevenson media: i2c: ov9281: Add support for 8 bit readout The sensor supports 8 bit mode as well as 10bit, so add the relevant code to allow selection of this. Signed-off-by: Dave Stevenson media: ov9281: Add 1280x720 and 640x480 modes Breaks out common register set and adds the different registers for 1280x720 (cropped) and 640x480 (skipped) modes Signed-off-by: Dave Stevenson Fixed picture line bug in all ov9281 modes Signed-off-by: Mathias Anhalt Added hflip and vflip controls to ov9281 Signed-off-by: Mathias Anhalt media: i2c: ov9281: Remove override of subdev name From the original Rockchip driver, the subdev was renamed from the default to being "mov9281 " whereas the default would have been "ov9281 ". Remove the override to drop back to the default rather than a vendor custom string. Signed-off-by: Dave Stevenson media: v4l2-subdev: add subdev-wide state struct Signed-off-by: Dom Cobley media: i2c: ov9281: Add fwnode properties controls Add call to v4l2_ctrl_new_fwnode_properties to read and create the fwnode based controls. Signed-off-by: Dave Stevenson media: i2c: ov9281: Sensor should report RAW color space Tested on Raspberry Pi running libcamera. Signed-off-by: David Plowman Partial revert "media: i2c: add ov9281 driver." This partially reverts commit 84e98e3a4f3eecb168ceb80231c3e8252929892e. The commit had merged some changes to other drivers with adding the ov9281 driver. Only the ov9281 parts have been reverted. --- drivers/media/i2c/imx477.c | 32 ++++++++++--------- drivers/media/i2c/irs1125.c | 15 ++++----- .../media/platform/bcm2835/bcm2835-unicam.c | 20 ++++++------ .../bcm2835-isp/bcm2835-v4l2-isp.c | 4 +-- 4 files changed, 36 insertions(+), 35 deletions(-) --- a/drivers/media/i2c/imx477.c +++ b/drivers/media/i2c/imx477.c @@ -1272,9 +1272,9 @@ static int imx477_open(struct v4l2_subde { struct imx477 *imx477 = to_imx477(sd);
