[PATCH 0/2] hw/i2c/dw: Add DesignWare I2C controller emulator

Posted by AlanoSong@163.com 1 month ago

Hi all,

This series try to add DesignWare I2C controller
according to DesignWare I2C databook v2.01a.

Cause DesignWare I2C controller is commonly used
on arm soc chip, I add it onto arm virt board,
and also an at24c eeprom for r/w operation.

I also add the I2C controller and at24c eeprom into
the acpi table of arm virt board.

The code above has been confirmed with i2c-tools under
linux v6.18 kernel driver.

Thanks for your review!
Alano Song.
