Subject: [PATCH v4 0/2] media: i2c: Add support for GC08A3 sensor
Date: Sun, 4 Feb 2024 14:15:36 +0800	[thread overview]
Message-ID: <20240204061538.2105-1-zhi.mao@mediatek.com> (raw)

This series adds YAML DT binding and V4L2 sub-device driver for Galaxycore's
GC08A3 8-megapixel 10-bit RAW CMOS 1/4" sensor, with an MIPI CSI-2 image data
interface and the I2C control bus.

The driver is implemented with V4L2 framework.
 - Async registered as a V4L2 sub-device.
 - As the first component of camera system including Seninf, ISP pipeline.
 - A media entity that provides one source pad in common.
 - Used in camera features on ChromeOS application.

Also this driver supports following features:
 - manual exposure and analog gain control support
 - vertical blanking control support
 - test pattern support
 - media controller support
 - runtime PM support
 - support resolution: 3264x2448@30fps, 1920x1080@60fps

v1: https://lore.kernel.org/linux-media/20231123115104.32094-1-zhi.mao@mediatek.com/

This series is based on linux-next, tag: next-20240202
Changes in v4:
- dts-binding files：
-- rename the titile of patch "dt-bindings"
-- use "sensor@31" as device node,according to Krzysztof's suggestion

- gc08a sensor driver：
-- use "ARRAY_SIZE(...)" directly in driver code, instead of macros
-- use pointer to corresponds an array entry of link_frequency
-- use variable of struc "mode" in function:gc08a3_get_selection()
-- declare ret as last in function:gc08a3_test_pattern()
-- fix some coding style by "checkpatch.pl --strict --max-line-length=80"
-- remove function:gc08a3_g_mbus_config()
-- use "v4l2_link_freq_to_bitmap()" API to parse driver-supported link frequencies
-- move runtime PM API before registering the sub-device in function:probe()

Thanks
