From e8beacbb85a5c1de1117400c5ddb450514a8372c Mon Sep 17 00:00:00 2001 From: Andreas Larsson Date: Fri, 15 Feb 2013 16:52:21 +0100 Subject: spi/spi-fsl-spi: Make driver usable in CPU mode outside of an FSL_SOC environment This makes the spi-fsl-spi driver usable in CPU mode outside of an FSL_SOC and even an powerpc environment by moving CPM mode functionality to a separate file that is only compiled and linked in an FSL_SOC environment and adding some ifdefs to hide types and functions or provide alternatives. For devicetree probing a "clock-frequency" property is used for clock frequency instead of calls to FSL_SOC-specific functions.
