From 3216e5512abdd1fc671ed8443ffc8fa9e4adc78c Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Tue, 27 Sep 2022 18:53:36 -0400 Subject: counter: Move symbols into COUNTER namespace Counter subsystem symbols are only relevant to counter drivers. A COUNTER namespace is created to control the availability of these symbols to modules that import this namespace explicitly.
