Hello everyone,

V8 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.

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 <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[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
