From b6305d62234642a37fa1a68d15e741cfc3428c45 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Tue, 31 Mar 2015 18:37:12 +0100 Subject: ahci: st: Update the DT example for how to obtain the PHY. The example is wrong in that the phys property should take a phandle to the phy port. Also with the changing over to generic PHY type constants we also update that as well.
