From 2f472ae6b1998af6d9a4ccc3f0d58781db21cafc Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 19 Nov 2014 16:26:59 +0100 Subject: [PATCH 1/4] ARM: shmobile: sh73a0 legacy/reference: Add missing INTCA0 clock for irqpin module This clock drives the irqpin controller modules. Before, it was assumed enabled by the bootloader or reset state. By making it available to the driver, we make sure it gets enabled when needed, and allow it to be managed by system or runtime PM.
