- 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.
- Submitted-by: Birger Koblitz <[email protected]>
