[PATCH 4/5] hw/i2c/Kconfig: Add an entry for the SMBus |
Date: |
Mon, 20 Jan 2020 11:07:24 -0600 |
From: Philippe Mathieu-Daudé <address@hidden>
The System Management Bus is more or less a derivative of the I2C
bus, thus the Kconfig entry depends of I2C.
Not all boards providing an I2C bus support SMBus.
Use two different Kconfig entries to be able to select I2C without
selecting SMBus.
