From: Charulatha V <charu@xxxxxx> 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: http://ns.spinics.net/lists/linux-omap/msg48167.html http://ns.spinics.net/lists/linux-omap/msg47989.html http://ns.spinics.net/lists/linux-omap/msg47827.html http://ns.spinics.net/lists/linux-omap/msg47830.html 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 Charulatha V (7): OMAP: GPIO: Make gpio_context part of gpio_bank structure OMAP: GPIO: Use flag to identify wkup dmn GPIO OMAP4: GPIO: Save/restore context OMAP: GPIO: handle save/restore ctx in GPIO driver OMAP2+: GPIO: make workaround_enabled bank specific OMAP: GPIO: Cleanup prepare_for_idle/resume OMAP: GPIO: use PM runtime framework arch/arm/mach-omap2/gpio.c | 6 + arch/arm/mach-omap2/pm34xx.c | 22 +- arch/arm/plat-omap/gpio.c | 766 ++++++++++++++++++-------------- arch/arm/plat-omap/include/plat/gpio.h | 3 +- 4 files changed, 439 insertions(+), 358 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
