Handling Signal1 in microchip-tcb-capture

[William Breathitt Gray]

Hello Kamel,

I was looking over the microchip-tcb-capture driver recently and noticed
that the code doesn't seem to account for Signal1. In particular, it
appears that mchp_tc_count_signal_read() and mchp_tc_count_action_read()
don't check the Signal id at all and just assume they are handling
Signal0. This creates a situation where the information returned for the
Signal1 sysfs attributes are just duplicated reports of Signal0.

What exactly is the relationship of Signal0 ("Channel A") and Signal1
("Channel B"); is SignalB only relevant when the counter device is
configured for quadrature mode?

Sincerely,

William Breathitt Gray
