Subject: [PATCH] realtek: Add support for RTL9300/RTL9310 I2C controller
|
|
|
|
This adds support for the RTL9300 and RTL9310 I2C controller.
|
|
The controller implements the SMBus protocol for SMBus transfers
|
|
over an I2C bus. The driver supports selecting one of the 2 possible
|
|
SCL pins and any of the 8 possible SDA pins. Bus speeds of
|
|
100kHz (standard speed) and 400kHz (high speed I2C) are supported.
