From: Charulatha V <[email protected]>
Do some more cleanup of OMAP GPIO driver and avoid usage of gpio_bank_count
and gpio_bank pointer array by means of maintaining a list.
Patch series is on following commit of linux-omap-pm (branch: wip/gpio-cleanup):
73ec20e00b9c02d5588dc83babb567527ed4394d
OMAP: GPIO: cleanup show revision, remove cpu_is checks, display only once
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
- OMAP4430-Blaze
GPIO module functionality testing (success on the following boards):
- OMAP2420-H4
- OMAP3430-SDP
- OMAP3430-Zoom2
- OMAP3630-Zoom3
- OMAP4430-SDP
- OMAP4430-Blaze
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
