From 026d70dcfe5de1543bb8edb8e50d22dc16863e6b Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Mon, 12 Jan 2026 17:48:10 -0500 Subject: [PATCH] clk: microchip: core: allow driver to be compiled with COMPILE_TEST This driver currently only supports builds against a PIC32 target. To avoid future breakage in the future, let's update the Kconfig and the driver so that it can be built with CONFIG_COMPILE_TEST enabled. Note that with the existing asm calls is not how I'd want to do this today if this was a new driver, however I don't have access to this hardware. To avoid any breakage, let's keep the existing behavior.
