[PATCH 1/4] i2c: busses: i2c-st: Add ST I2C controller

2013-10-01 Thread Maxime COQUELIN
This patch adds support to SSC (Synchronous Serial Controller) I2C driver. This IP also supports SPI protocol, but this is not the aim of this driver. This IP is embedded in all ST SoCs for Set-top box platorms, and supports I2C Standard and Fast modes. Signed-off-by: Maxime Coquelin Cc: Sriniva
