From 55b604ae4b50023356064f43c24ea896ee8e400a Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Mon, 2 Jun 2014 10:10:13 +0100 Subject: [PATCH] mmc: mmci: Add Qualcomm Id to amba id table This patch adds a fake Qualcomm ID 0x00051180 to the amba_ids, as Qualcomm SDCC controller is pl180, but amba id registers read 0x0's. The plan is to remove SDCC driver totally and use mmci as the main SD controller driver for Qualcomm SOCs.
