Subject: decode: start collecting internal state (samplerate)
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=69110b5cbe99a54937f108d239592e5afb55d008;p=sigrok-cli.git

decode: start collecting internal state (samplerate)

Introduce variables which hold the internal state during decoder
operation so far. Start by adding a "samplerate used by protocol
decoders". This is motivated by the pending Google Trace Event
feature addition.
