The mach/ and asm/ includes are not needed in davinci_keyscan, but they
will cause build problems once we make mach/irqs.h a private header for
mach-davinci.
Remove all unused header includes.

The intc_host_map field in struct davinci_soc_info is not used by any
board. Remove it as part of the interrupt support cleanup.

We need to create an irq domain if we want to select SPARSE_IRQ. The
cp-intc driver already supports it, but aintc doesn't. Use the helpers
provided by the generic irq chip abstraction.

In order to support SPARSE_IRQ we first need to make davinci use the
generic irq handler for ARM. Translate the legacy assembly to C and
put the irq handlers into their respective drivers (aintc and cp-intc).

davinci_intc_base is defined globally in common.c. Define separate
local variables for the aintc and cp-intc drivers and remove the
global one.

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Once we select SPARSE_IRQ, the interrupt numbers defined in mach/irqs.h
will only signify the hardware interrupt offsets, not the interrupt
numbers seen by linux. Introduce a wrapper macro that translates the
hwirq number to virtual numbers. For now it's just a dummy. Use that
macro when specifying the interrupts in resources for platform devices.

Everything is in place now for SPARSE_IRQ. Select it and set
DAVINCI_INTC_START to NR_IRQS.
We now need to include mach/irqs.h in a couple places as it is no
longer indirectly included after selecting SPARSE_IRQ.

The existence of irqs.h in mach-davinci/include/mach only makes sense
without SPARSE_IRQ as it's then expected to define NR_IRQS and is
included from asm/irq.h. As we now support SPARSE_IRQ, this header can
be moved to mach-davinci and used as the source of HW interrupt numbers.
While updating the includes in various files - also rearrange the
headers by directory (linux/asm/mach).

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We're going to extend the davinci_irq_init() function with a config
structure so we can drop the intc-related fields from davinci_soc_info.
Once we do it, we won't be able to use this routine directly as the
init_irq callback. Wrap the calls in additional helpers that don't
take parameters and can be assigned to init_irq.

Since no offset goes past 0xff - let's drop the 00 prefix for better
readability. While we're at it: convert all hex numbers to lower-case.

Raplace all calls to __raw_readl() & __raw_writel() with readl_relaxed()
and writel_relaxed() respectively. It's safe to do as there's no
endianness conversion being done in the code.

Add a config structure that will be used by aintc-based platforms.
It contains the register range resource, number of interrupts and
a list of priorities.

Modify the aintc driver to take all its configuration from the new
config structure. Stop referencing davinci_soc_info in any way.
Move the declaration for davinci_aintc_init() to irq-davinci-aintc.h
and make it take the new config structure as parameter. Convert all
users to the new version.

Instead of dumping stack traces, just print a specific error message
in aintc driver.

Add a missing call to request_mem_region() before calling ioremap() to
make sure the region is not being used by anyone else.

I've been unable to figure out exactly why, but it seems that the
IRQ_TINT1_TINT34 interrupt for timer 1 needs to be handled as a
level irq, not edge like all others.
Let's move the handler setup out of the aintc driver where it's lived
since the beginning and into the dm* SoC-specific files where it
belongs.

I've said it on v2, I'm repeating it on v3. There is no point in
duplicating this pointless hack on and on again. If there is a driver
using this interrupt, move the setup there, and fix the irq_set_type
callback.
If nothing is using it, remove it altogether.
Thanks,
M.

Alright, fine with me as well. Dropping the hack is fine. And I think
that just boils down to discarding this patch.

Actually this patch should simply remove the call to irq_set_handler()
from the driver.

The aintc driver has now been cleaned up. Move it to drivers/irqchip
where it belongs. There's no device-tree support for any dm* board so
there's no IRQCHIP_OF_DECLARE() - there's only the exported init
function called from machine code.

There's no need to have a local header for cp-intc. Move the only
declaration for a public function to common.h. Move all register
offsets into the driver source file and drop all unused defines.
Make cp_intc_of_init() static.

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We're going to extend the cp_intc_init() function with a config
structure so we can drop the intc-related fields from davinci_soc_info.
Once we do it, we won't be able to use this routine directly as the
init_irq callback. Wrap the calls in additional helpers that don't
take parameters and can be assigned to init_irq.

Add a config structure that will be used by cp-intc-based platforms.
It contains the register range resource and the number of interrupts.

Use lowercase letters in hexadecimal numbers in the cp-intc driver as
is done in most of the kernel code base.

Modify the cp-intc driver to take all its configuration from the new
config structure. Stop referencing davinci_soc_info in any way.
Move the declaration for davinci_cp_intc_init() to
irq-davinci-cp-intc.h and make it take the new config structure as
parameter. Convert all users to the new version.
Also: since the two da8xx SoCs default all irq priorities to 7, just
drop the priority configuration at all and hardcode the channels to 7.
It will simplify the driver code and make our lives easier when it
comes to device-tree support.

Raplace all calls to __raw_readl() & __raw_writel() with readl_relaxed()

endianness conversion being done in the code.
