From 7326e38ffe894d0cd2904704b7d8c53d4a55d752 Mon Sep 17 00:00:00 2001 From: Ganesan Ramalingam Date: Fri, 13 Jul 2012 19:14:25 +0530 Subject: i2c: i2c-ocores: support for 16bit and 32bit IO Some architectures supports only 16-bit or 32-bit read/write access to their IO space. Add a 'reg-io-width' platform and OF parameter which specifies the IO width to support these platforms. reg-io-width can be specified as 1, 2 or 4, and has a default value of 1 if it is unspecified.
