From 5ca032ee21cdabd08fb368ce3f02fa8906b0ef5f Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 14 Sep 2012 16:16:08 +0100 Subject: ASoC: Ux500: Move MSP pinctrl setup into the MSP driver In the initial submission of the MSP driver msp1 and msp3's associated pinctrl mechanism was passed back to platform code using a plat_init() call-back routine, but it has no place in platform code. The MSP driver should set this up for the appropriate ports. Instead we use a use_pinctrl identifier which is passed from platform_data/Device Tree which indicates which ports should use pinctrl.
