From 1a297286868e13274ab02ec0626a00054fb0a5de Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 17 Apr 2009 11:39:38 +0200 Subject: ASoC: pxa-ssp: Don't use SSCR0_SerClkDiv and SSCR0_SCR Those macros are just screwed as soon as CONFIG_PXA25x is enabled. This patch - changes ssp_set_scr to take an ssp_dev pointer instead of ssp_device - adds a corresponding ssp_get_scr function.

Adding also Peter Ujfalusi as a second contact to OMAP core drivers since I won't have anymore access to non-public OMAP documentation in the future and Peter is working with these drivers as well.
