[PATCH v1 02/11] mmc: mmci: Add Qualcomm Id to amba id table
From: Srinivas Kandagatla srinivas.kandaga...@linaro.org
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.
