It separates the DT initialization for tzic and gpt from non-DT code
path, so that base address and irq can retrieved from device tree
rather than static definition.
With the DT initialization flow corrected as above, the generic_chip
irq_domain support is adopted for tzic interrupt controller, so that
the irq_domain initialization for tzic in imx5 DT platform code can be
removed.

I'm trying to save one more occurrence of "#ifdef CONFIG_OF", or I
to move around the whole block wrapped by #ifdef, which will make
unnecessary diffstat churn.
I hope we can stop this nasty #ifdef at some point by select CONFIG_OF
for the imx architecture.

I guess that's the situation we have to live with until the non-DT
support gets completely removed.

This patch changes all the static gpio irq number assigning with
IMX_GPIO_TO_IRQ() to run-time assigning with gpio_to_irq call, and
in turn eliminates the macro IMX_GPIO_TO_IRQ().

From: Shawn Guo @ 2012-02-15 18:47 UTC (permalink / raw)
To: linux-arm-kernel
This patch changes all the static gpio irq number assigning with
IRQ_GPIOA() ... IRQ_GPIOF() to run-time assigning with gpio_to_irq
call, and in turn eliminates these macros.
Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Do we really need this new macros?
Why not use the standard IMX_GPIO_NR macro instead?

They are not brand new. They are here to help a plain translation
from IRQ_GPIOx() to IMX_GPIOx().

It can be another patch, if you are interested.

It adopts irq_domain for imx gpio interrupt support, and fixes the
translation between irq and gpio number for DT users.
As the results, macro MXC_GPIO_IRQ_START is referenced nowhere in
gpio-mxc driver, and the gpio irq_domain initilization in DT platform
code is removed.

Now, macro MXC_GPIO_IRQ_START is referenced nowhere, so remove it.

Series looks okay to me on a brief review. I'll let Rob pick it up since
it needs to be based on top of his generic_irq work. There will still need
to be some rebasing while I stablize the irq_domain tree, but I'll try to
do that ASAP.

Thanks for looking at it, Grant. But it does not work properly with
your irqdomain/next yet. It requires some little change on irq_domain
side, which is mentioned in another reply to you.
