From b8341f1c39df8708ee783038d8abb2b50dd83fac Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 29 Jul 2017 11:35:15 -0600 Subject: dm: sata: Update the AHCI uclass to support operations At present the AHCI uclass is just a shell and we still use the global functions to access SATA. Fix this by adding operations to the uclass.
