[PATCH v7 0/3] media: i2c: Introduce driver for the TW9900 video decoder

Hello everyone,

V7 of the series adding support for the Techwell TW9900 multi standard decoder.
It's a pretty simple decoder compared to the TW9910, since it doesn't have a
built-in scaler/crop engine.

The v6 is based on the fifth iteration of the series introducing the
tw9900 driver: sent 01 Apr 2021 [1]

v6 => v7:
- added powerdown-gpios and input ports to dt-bindings
- added #include <linux/bitfield.h> to fix a Warning from the kernel
robot
- removed a dev_info and replaced a dev_err by dev_err_probe

v5 => 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
