From 14e26bcfa700b507a805eb30c72e3b6a1ba19d7f Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 11 Jan 2013 03:19:02 +0000 Subject: mxs: ssp: Pull out the SSP bus to regs conversion Create function which converts SSP bus number to SSP register pointer. This functionality is reimplemented multiple times in the code, thus make one common implementation. Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.
