Subject: [PATCH V4 3/3] ARM: tegra: move timer.c to drivers/clocksource/
From: Stephen Warren <swarren@...dia.com>
Move arch/arm/mach-tegra/timer.c to drivers/clocksource/tegra20_timer.c
so that the code is co-located with other clocksource drivers, and to
reduce the size of the mach-tegra directory.
Signed-off-by: Stephen Warren <swarren@...dia.com>
---
v4: Adjust to changes in the rest of the patch series.
v3: Rework using CLKSRC_OF_MATCH_TABLE() for registration, rather than a
manually maintained table in clksrc-of.c.
v2: Rebase on ARM sys_timer rework, and addition of clocksource_of_init().
