GPIO interface between DVB sub-drivers (bridge, demod, tuner)

2012-07-12 Thread Antti Palosaari
I am looking kinda standardized interface for setting GPIOs between the DVB drivers chip drivers. For most typical example there is LNA which is controlled by RF-tuner GPIO. That kind of LNA controlling logic belongs to interface driver thus I will need to call demod driver from bridge in order
