From da15b409ef4c56e9741deddb91798370802d1d02 Mon Sep 17 00:00:00 2001 From: Shawn Tu Date: Tue, 11 Jan 2022 16:08:27 +0100 Subject: [PATCH] media: hi847: Add support for Hi-847 sensor Add a V4L2 sub-device driver for Hynix Hi-847 image sensor. This is a camera sensor using the I2C bus for control and the CSI-2 bus for data. This driver supports following features: - manual exposure and analog/digital gain control support - vblank/hblank control support - test pattern support - media controller support - runtime PM support - vflip/hflip control support - keep SGRBG10 Bayer order output - support following resolutions: + 3264x2448 at 30FPS + 1632x1224 at 60FPS [Sakari Ailus: Wrapped a few long lines.] Signed-off-by: Shawn Tu Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab --- MAINTAINERS | 6 + drivers/media/i2c/Kconfig | 13 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/hi847.c | 3012 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 3032 insertions(+) create mode 100644 drivers/media/i2c/hi847.c diff --git a/MAINTAINERS b/MAINTAINERS index 2767874..22c09cc 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -8896,6 +8896,12 @@ L: linux-media@vger.kernel.org S: Maintained F: drivers/media/i2c/hi846.c +HYNIX HI847 SENSOR DRIVER +M: Shawn Tu +L: linux-media@vger.kernel.org +S: Maintained +F: drivers/media/i2c/hi847.c + Hyper-V/Azure CORE AND DRIVERS M: "K.
