From 7000fe8c7a072214d90ca1fc8189b25c30fdd918 Mon Sep 17 00:00:00 2001 From: Abhilash Kesavan Date: Tue, 20 Nov 2012 18:20:38 +0900 Subject: ARM: EXYNOS: Setup legacy i2c controller interrupts On Exynos5 we have a new high-speed i2c controller. The interrupt sources for the legacy and new controller are muxed and are controlled via the SYSCON I2C_CFG register. At reset the interrupt source is configured for the high-speed controller, to continue using the old i2c controller we need to modify the I2C_CFG register.
