From 52d7e430cff3f076d5ae5587e94f2e9b832b85d2 Mon Sep 17 00:00:00 2001 From: Shinya Kuribayashi Date: Fri, 6 Nov 2009 21:50:02 +0900 Subject: i2c-designware: i2c_dw_func: Set I2C_FUNC_SMBUS_foo bits Set proper I2C_FUNC_SMBUS_* bits so that the driver could be used with some utilities requiring SMBus functionalities, such as i2c-tools. Note that DW I2C core doesn't support I2C_FUNC_SMBUS_QUICK, as it's not capable of zero-length data transactions.
