Hi Russell, On ven., janv. 13 2017, Russell King [off-list ref] wrote:
Testing with an Armada 8040 board shows that adding the generic-ahci compatible to the CP110 AHCI nodes gets us working AHCI on the board. A previous patch series posted by Thomas Petazzoni was retracted when it was realised that the IP was supposed to be, and is, compatible with the standard register layout. Add this compatible.
Applied on mvebu/dt64 (not that it didn't apply cleanly on the mainline because in mainline we don't use yet the ICU for the interrupt) Thanks, Gregory
