It's a pretty simple decoder compared to the TW9910, since it doesn't have a built-in scaler/crop engine. v8 => v9: - added a "depends on" GPIOLIB, PM and "select" V4L2_ASYNC to Kconfig - reworked the locking to protect the tw9900->streaming global state - folded power_on and power_off into runtime_resume and runtime_suspend callbacks - used pm_runtime_resume_and get instead pm_runtime_get_sync v7 => v8: - fixed the number of analog input ports: it is just one. - added endpoints of the analog input port - added vdd-supply to the required in the dt-binding documentation - added back pm_runtime - added a mutex to Serialize access to hardware and current mode configuration - split get_fmt and set_fmt callbacks - removed the tw9900_cancel_autodetect() v6 => v7: - added powerdown-gpios and input ports to dt-bindings - added #include to fix a Warning from the kernel robot - removed a dev_info and replaced a dev_err by dev_err_probe v5[1] => v6: - dropped .skip_top and .field in the supported_modes - added error handling for the i2c writes/reads - added the colorimetry information to fill_fmt - removed pm_runtime - added the g_input_status callback - dropped SECAM - dropped the non-standard PAL/NTSC variants Any feedback is appreciated, Mehdi Djait media_tree, base-commit: 3e238417254bfdcc23fe207780b59cbb08656762 [1] https://lore.kernel.org/linux-media/20210401070802.1685823-1-maxime.chevallier@bootlin.com/ Mehdi Djait (3): dt-bindings: vendor-prefixes: Add techwell vendor prefix media: dt-bindings: media: i2c: Add bindings for TW9900 media: i2c: Introduce a driver for the Techwell TW9900 decoder .../bindings/media/i2c/techwell,tw9900.yaml | 137 +++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 6 + drivers/media/i2c/Kconfig | 15 + drivers/media/i2c/Makefile | 1 + drivers/media/i2c/tw9900.c | 777 ++++++++++++++++++ 6 files changed, 938 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/techwell,tw9900.yaml create mode 100644 drivers/media/i2c/tw9900.c
