Subject: [PATCH 4/7] OMAP: GPIO: handle save/restore ctx in GPIO driver
Date: Mon, 18 Apr 2011 20:36:54 +0530 [thread overview]
Message-ID: <1303139217-10285-5-git-send-email-charu@ti.com> (raw)
In-Reply-To: <no>
From: Charulatha V <charu@ti.com>
Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle()
functions to handle save context & restore context respectively in the
OMAP GPIO driver itself instead of calling these functions from pm specific
files. For this, in gpio_prepare_for_idle(), use
omap_device_get_context_loss_count() and in gpio_resume_after_idle()
call it again. If the count is different, do restore context.
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. Hence correct this
so that context lost count is modified before calling
omap_gpio_resume_after_idle().
omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle()
do nothing if none of the GPIOs in a bank is being used.
Also remove usage of cpu_is_* checks from the above mentioned
functions and fix the multi-line comment style

Note that the usage of bank->method checks would be re-addressed
during OMAP GPIO cleanup series which would follow this patch series

Subject: [PATCH 4/7] OMAP: GPIO: handle save/restore ctx in GPIO driver
Date: Mon, 18 Apr 2011 20:36:54 +0530 [thread overview]
Message-ID: <1303139217-10285-5-git-send-email-charu@ti.com> (raw)
In-Reply-To: <no>
From: Charulatha V <charu@ti.com>
Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle()
functions to handle save context & restore context respectively in the
OMAP GPIO driver itself instead of calling these functions from pm specific
files. For this, in gpio_prepare_for_idle(), use
omap_device_get_context_loss_count() and in gpio_resume_after_idle()
call it again. If the count is different, do restore context.
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. Hence correct this
so that context lost count is modified before calling
omap_gpio_resume_after_idle().
omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle()
do nothing if none of the GPIOs in a bank is being used.
Also remove usage of cpu_is_* checks from the above mentioned
functions and fix the multi-line comment style
