Subject: [PATCH v2 0/4] Support timer drivers as loadable modules
Date: Tue, 14 Feb 2023 18:53:10 +0800	[thread overview]
Message-ID: <20230214105412.5856-1-walter.chang@mediatek.com> (raw)

From: Walter Chang <walter.chang@mediatek.com>

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
