From 16b2e6e2f31dda41f114aa0acade04f7e10f67c9 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 26 Jan 2012 11:26:52 -0700 Subject: irq_domain: Create common xlate functions that device drivers can use Rather than having each interrupt controller driver creating its own barely unique .xlate function for irq_domain, create a library of translators which any driver can use directly. v5: - Remove irq_domain_xlate_pci(). It was incorrect.
