Subject: [v2 0/7] OMAP: GPIO: Use PM runtime framework
Date: Mon, 18 Apr 2011 20:36:50 +0530 [thread overview]
Message-ID: <1303139217-10285-1-git-send-email-charu@ti.com> (raw)
In-Reply-To: <no>
From: Charulatha V <charu@ti.com>
Use PM runtime framework in OMAP GPIO driver.
Patch series is based on mainline rc3 following commit
commit a1b49cb7e2a7961ec3aa8b64860bf480d4ec9077
Merge branch 'i2c-for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging
Changes in v2:
* Use a per-bank flag 'looses_context' (using pwrdm_can_ever_lose_context())
instead of using the powerdomain name
* Make use of omap_device_get_context_loss_count() to decide on if restore
context needs to be done.
* Do not remove #ifdef CONFIG_ARCH_OMAP2PLUS
* Do not use pm_runtime_suspended() before calling pm_runtime_get_sync/put_sync
* use IS_ERR_VALUE() instead of '< 0' in "if" conditions
(Thanks to Kevin and Paul for the above suggestions)
Previous version of this patch series is available at:

Compile tested for:
- omap1_defconfig
- omap2plus_defconfig
Boot test (success on the following boards):
- OMAP1710-H3
- OMAP2420-H4
- OMAP3430-SDP
- OMAP3430-Zoom2
- OMAP3630-Zoom3
- OMAP4430-SDP
GPIO module functionality testing (success on the following boards):
- OMAP2420-H4
- OMAP3430-SDP
- OMAP3430-Zoom2
- OMAP3630-Zoom3
- OMAP4430-SDP
PM Testing (success as given below):
OMAP3430-SDP: retention, off_mode, system_wide suspend, gpio wakeup
OMAP3630-Zoom3: retention, system_wide suspend
using the following:
echo 5 > /sys/devices/platform/omap/omap_uart.0/sleep_timeout
echo 5 > /sys/devices/platform/omap/omap_uart.1/sleep_timeout
echo 5 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout
echo 5 > /sys/devices/platform/omap/omap_uart.3/sleep_timeout
echo '5' > /debug/pm_debug/wakeup_timer_seconds
echo 1 > /debug/pm_debug/sleep_while_idle
echo 1 > /debug/pm_debug/enable_off_mode
echo mem > /sys/power/state
