From 912bfe76528c287bc4812521b8d53366954b39a5 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 19 Aug 2012 14:05:59 -0300 Subject: ARM: clk-imx25: Fix SSI clock registration SSI block has two types of clock: ipg: bus clock, the clock needed for accessing registers. per: peripheral clock, the clock needed for generating the bit rate. Currently SSI driver only supports slave mode and only need to handle the ipg clock, because the peripheral clock comes from the master codec. Only register the ipg clock and do not register the peripheral clock for ssi.

This is because the internal irqs now start at an offset of NR_IRQS_LEGACY. The patch fixed this up, but missed the i.MX25 timer which used a hardcoded value instead of a define. This patch introduces a define for the timer irq and uses it.
