*	designware_i2c: Added s/w generation of stop bit	Armando Visconti	2012-12-11	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	In the newer versions of designware i2c IP there is the possibility of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically requires the s/w to generate the stop bit condition directly, as the h/w will not automatically generate it when TX_FIFO is empty. To avoid generation of an extra 0x0 byte sent as data, the IC_STOP command must be sent along with the last IC_CMD. This patch always writes bit[9] of ic_data_cmd even in the older versions, assuming that it is a noop there. Signed-off-by: Armando Visconti <armando.visconti@st.com>
*	i2c: Add support for designware i2c controller	Vipin KUMAR	2012-04-24	1	-0/+146
	Earlier, a driver exists in the u-boot source for designware i2c interface. That driver was specific to spear platforms. This patch implements the i2c controller as a generic driver which can be used by multiple platforms The driver files are now renamed to designware_i2c.c and designware_i2c.h and these are moved into drivers/i2c folder for reusability by other platforms Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>
