Subject: [PATCH 6/7] OMAP: GPIO: Cleanup prepare_for_idle/resume
Date: Mon, 18 Apr 2011 20:36:56 +0530 [thread overview]
Message-ID: <1303139217-10285-7-git-send-email-charu@ti.com> (raw)
In-Reply-To: <no>
From: Charulatha V <charu@ti.com>
Use a function named gpio_bank_handle_idle() in
omap_gpio_prepare_for_idle() to do the following:
* debounce clock disable
* if the next powerdomain state for the bank is off-mode:
- remove triggering for all non-wakeup GPIOs (this is handled by
a new function named omap_gpio_idle_handle_errata_i468())
- save context
Also handle omap_gpio_resume_after_idle() in a
similar way, using a function gpio_bank_handle_resume().
This would be helpful while modifying OMAP GPIO driver to use
PM runtime framework.
