Subject: [PATCH V3 0/5] ARM: OMAP2+: Add device-tree support for timers
Date: Wed, 17 Oct 2012 13:01:08 -0500 [thread overview]
Message-ID: <1350496873-21337-1-git-send-email-jon-hunter@ti.com> (raw)
This series adds device-tree support for the timers on OMAP2+ devices
including AM33xx.
Testing:
1. I have booted tested this series on OMAP2420 H4, OMAP3430 Beagle, OMAP4430
Panda and AM335x Beagle Bone with/without ...
a). device-tree present
b). CONFIG_OMAP_32K_TIMER set
c). kernel boot parameter "clocksource=gp_timer" present
2. I have tested the all the timers (not used by the kernel as sys-timers) on
OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda with/without device-tree with
this series. The testing includes ...
a. Configuring, starting a timer and checking the counter value is
incrementing.
b. Testing timer overflow interrupt when timer expires.
c. Using different clock sources to operate the timer with.
V3 changes:
- Removed definition "TIMER_PROP_ALWON" per Rob Herring's feedback
- Updated OMAP system timer (clock-events and clock-source) code so that
HWMOD is NOT used for getting resource (memory and interrupt) information
when device-tree is present.
V2 changes:
- Remove use of device-tree alias property
- Migrate OMAP timers to request timers by property instead of device ID
- Include OMAP2 support
