From d7ca4c755a82eda8f0fc4f72c52130056b28c7d2 Mon Sep 17 00:00:00 2001 From: "Manjunathappa, Prakash" Date: Thu, 28 Mar 2013 18:41:59 +0530 Subject: ARM: davinci: mmc: derive version information from device name Remove specifying mmc controller IP version information via platform data, instead specify device name so that driver derives it from platform_device_id table. Also change the clock node name to match the changed dev_id. Tested on da850-evm to make sure driver loads without clk_get failures.
