From 2374a5399b7263eb1afc6b5522a56ebf9f0b8636 Mon Sep 17 00:00:00 2001 From: Naveen Krishna Ch Date: Tue, 16 Sep 2014 15:03:17 +0530 Subject: i2c: exynos: add support for HSI2C module on Exynos7 The HSI2C module on Exynos7 differs in the transfer status bits. Transfer status bits were moved to INT_ENABLE and INT_STATUS registers This patch adds support for the HSI2C module on Exynos7. 1. Implementes a "hw" field in the variant struct to distinguish the hardware. 2.
