Subject: [PATCH v4 REPOST 04/20] gpio/omap: fix pwrdm_post_transition call sequence
Date: Sat, 16 Jul 2011 13:45:36 +0530	[thread overview]
Message-ID: <1310804152-9243-5-git-send-email-tarun.kanti@ti.com> (raw)
In-Reply-To: <1310804152-9243-1-git-send-email-tarun.kanti@ti.com>

From: Charulatha V <charu@ti.com>

The context lost count is modified in omap_sram_idle() path when
pwrdm_post_transition() is called. But pwrdm_post_transition() is called
only after omap_gpio_resume_after_idle() is called. Correct this so that
context lost count is modified before calling omap_gpio_resume_after_idle().

This would be useful when OMAP GPIO save/restore context is called by
the OMAP GPIO driver itself.
