In Capture mode, the RC register serves as a compare register for the
Timer Counter Channel. When a the Counter Value reaches the RC value, a
RC Compare event occurs (COUNTER_EVENT_THRESHOLD). This patch exposes
the RC register to userspace as the 'compare' Count extension, thus
allowing users to configure the threshold condition for these events.

I'm assuming you'll merge it with my capture extensions patch. Will this
`compare` extension be carried over to 104-quad-8 as well? Otherwise:

Thank you for the Ack, I've merged this series now and pushed it to
counter-next.

The compare functionality is already exposed through the `preset`
component in the 104-quad-8 module, so I decided not to add a `compare`
because it felt redundant. However, I'm certain `compare` will be useful
in future drivers so that's why I want to get it merged with the rest of
the microchip-tcb-capture changes. :-)

Best regards,
