From 117053f77a5a4d055ec4fc7b4f6639045a24fefd Mon Sep 17 00:00:00 2001 From: Vasanth Ananthan Date: Mon, 11 Nov 2013 16:50:20 +0530 Subject: i2c: s3c2410: Add polling mode support This patch adds polling mode support for i2c-s3c2410 driver.The SATA PHY controller's CMU and TRSV block's are of I2C register map in exynos5250.These blocks can be configured using i2c. But i2c controller instance on which these block's sits lacks an interrupt line.Also the current i2c-s3c2410 driver is only interrupt driven, thus a polling mode support is required in the driver for supporting this controller. This patch adds this support to the driver.
