Coreboot Gains A Hybrid Graphics Driver For Lenovo ThinkPads

Landing in Coreboot Git this week is a "hybrid graphics driver" that benefits seemingly all Lenovo laptops (except the mux-less models) with dual GPUs.

This hybrid graphics driver in the Coreboot realm simply allows connecting the display panel to either the integrated GPU or discrete graphics processor. This hybrid driver basically comes down to setting the GPIO pins for the panel LVDS signal so you can route the display to whichever GPU you want from Coreboot.

Among the Lenovo ThinkPads supported by Coreboot, this driver should be of use to the dual-GPU ThinkPads of the T400, T420, T420S, T520, and T530 series. More details via this commit.
