[PATCH 0/2] counter: Introduce the compare component

[William Breathitt Gray <wbg@kernel.org>]

In previous drivers, we have exposed compare operations as part of a
larger set of functionalities; such as preseting a Count channel,
defining ceiling and floor boundaries, etc. However, we've lacked a
standard way to expose the compare operation in its strict sense as a
threshold comparison.

The need has become apparent in the microchip-tcb-capture module, which
requires a way to configure the threshold value provided by the RC
register for compare operations. To that end, a new compare component is
introduced with a helper macro COUNTER_COMP_COMPARE() to create such.
