Subject: [PATCH 00/15] OMAP: GPIO: Cleanup OMAP GPIO driver
Date: Tue, 24 May 2011 19:54:39 +0530	[thread overview]
Message-ID: <1306247094-25372-1-git-send-email-tarun.kanti@ti.com> (raw)

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):
commit d04952091a3b9b4b47696cee48e92a9173fd9ffb
GPIO: OMAP: cleanup show revision, remove cpu_is checks, display only once

Diff summary between RFC(prev version) and this version:
*Patches 0012*-0015* are added to the series
*Call gpio_save(restore)_context from OMAP GPIO driver instead
of calling them from PM sepcific funcs
	-For this, few more patches (patches 0004*-8*) are added
		to the series
*Move mpuio_init() from probe() to omap_gpio_mod_init()
*Correctly add the wake set/clear/status regs offsets at omap16xx_gpio_regs
*Remove usage of unnecessary variable "offset" locally inside prepare_for_idle()
*wake_set/clear related access is done only after validity check

Test Details:
Compile tested for omap1_defconfig and omap2plus_defconfig.
Bootup success on OMAP1710-H3.
Functional testing success on OMAP2430-SDP, OMAP3430-SDP, OMAP4430-SDP.
PM Testing success on OMAP3430-SDP: retention, off_mode, system_wide
suspend and gpio wakeup.
