Subject: [PATCH V1] i2c: xgene: Add support for I2C_FUNC_I2C functionality
Date: Wed, 26 Apr 2017 11:41:45 +0700 [thread overview]
Message-ID: <1493181705-18531-1-git-send-email-tnhuynh@apm.com> (raw)
From: Tin Huynh <tnhuynh@apm.com>
Certain I2C slave drivers, such as the pca95xx, require
only I2C operations instead of SMBus extensions.
This patch adds I2C_FUNC_I2C functionally to support those drivers.
