From 45d2918520b2d8e640e4fb3fbf664dfb823dc520 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Tue, 27 Sep 2022 18:53:40 -0400 Subject: counter: Introduce the Count capture component Some devices provide a latch function to save historic Count values. This patch standardizes exposure of such functionality as Count capture components. A COUNTER_COMP_CAPTURE macro is provided for driver authors to define a capture component. A new event COUNTER_EVENT_CAPTURE is introduced to represent Count value capture events.
