I haven't examined this yet enough, but for the background information I can
say I have one device which needs this. There is tuner behind demodulator,
but instead of normal I2C-gate switch, it is rather much likely repeater.
All tuner commands are send to the demod which then writes those to the
tuner.
DD = demod I2C addr
TT = tuner I2C addr
Bn = payload data
traditional I2C send to the tuner:
TT>> B0 B1 B2 ...
demod as repeater send to the tuner:
DD>> TT B0 B1 B2 ...
You can accomplish this by having the demod create an i2c adapter
instance, which generates i2c commands to the bridge. Then when
instantiating the tuner subdev, pass a pointer to the demod's i2c
adapter instead of the i2c adapter provided by the bridge.
No changes required to the core framework.
Thank you Devin. I didn't realized that earlier. It worked just fine.
