From e5c0fc4185c551c270868dcb6573604db2bc3171 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 25 Jan 2012 10:42:52 +0000 Subject: ARM: sa1111: change devid to be a bitmask Change the sa1111 device id to be a bitmask. This allows us to specify the actual device, while allowing a single driver to bind to both PS2 devices.
