From baf1c5d2a08c828d6333e0a37bcdf5afb3d5d003 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Sat, 12 Apr 2008 20:08:16 +0100 Subject: [PATCH] [ARM] 4971/1: pxaficp_ir: provide startup and shutdown hooks Let platform do some specific initialisation and cleanup things during pxaficp_ir probing and removing. E.g. this can be usefull to request/free gpios used by the platform to control the transceiver.
