This set of patches aims to make SoC related timer drivers, such as
timer-mediatek.c become loadable modules for the Generic Kernel Image
(GKI).

This driver registers an always-on timer as tick_broadcast_device on
MediaTek SoCs. If the system does not load this module at startup,
system will also boot normally by using built-in architecture timer
(in this case is Arm Generic Timer) instead.

The first three patches export functions and remove __init markings to
support loadable timer modules.

The fourth patch makes timer-mediatek.c become loadable module for GKI.

[v2]
- Convert timer-mediatek.c driver to loadable module

Chun-Hung Wu (4):
time/sched_clock: Export sched_clock_register()
clocksource/drivers/mmio: Export clocksource_mmio_init()
clocksource/drivers/timer-of: Remove __init markings
clocksource/drivers/timer-mediatek: Make timer-mediatek become
loadable module
