From dfa762e1c31c30607e4e5259f287dd3e174cbcc3 Mon Sep 17 00:00:00 2001 From: "Steven J. Hill" Date: Wed, 10 Apr 2013 16:28:36 -0500 Subject: MIPS: Refactor GIC clocksource code. Reorganize some of the GIC clocksource driver code. Below is a list of the various changes. * No longer select CSRC_GIC by default for Malta platform. * Limit choice for either the GIC or R4K clocksource, not both. * Change location in Makefile. * Created new 'gic_read_count' function in common 'irq-gic.c' file. * Change 'git_hpt_read' function in 'csrc-gic.c' to use new function. * Surround GIC specific code in Malta platform code with #ifdef's. * Only initialize the GIC clocksource if it was selected. Original code called it unconditionally if a GIC was found. Signed-off-by: Steven J.
