[Qemu-devel] [PATCH v6 8/8] aspeed: add the pc9552 chips to the witherspoon machine
Posted by Cédric Le Goater 8 years, 3 months ago
The pca9552 LED blinkers on the Witherspoon machine are used for leds
but also as GPIOs to control fans and GPUs.

I expect one day that the full "pca9550,1,2,3" device family will 
exist and I am not sure there is much point in adding a define for 
each. I should probably remove the TYPE_PCA9552.
