Bartosz Golaszewski a248f524ea ARM: davinci: da830: switch to using the clocksource driver
We now have a proper clocksource driver for davinci. Switch the da830
platform to using it.

Bartosz Golaszewski d470df3bc5 ARM: davinci: WARN_ON() if clk_get() fails
Currently the timer code checks if the clock pointer passed to it is
good (!IS_ERR(clk)). The new clocksource driver expects the clock to
be functional and doesn't perform any checks so emit a warning if
clk_get() fails. Apply this to all davinci platforms.

Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Move the declaration for davinci_cp_intc_init() to

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.

For modules having single clock, clk_get should be done with dev_id.
But current davinci implementation handles multiple instances

platform_device_register for each instance and clk_get on dev_id.

This patch helps get rid of the following sparse warnings
of the type:

arch/arm/mach-davinci/da830.c:1026:3: warning: Initializer entry defined twice
arch/arm/mach-davinci/da830.c:1027:3:   also defined here

coming from the irq priorities array init.

Apart from one instance of genuinie repetition, most are are instances
of multiple #defines of the same interrupt number. I have not
removed the multiple definitions from the irq.h file in the hope
that someone might decide to use them as shared interrupts at some
point of time. The priority initialization however needs to be done
only once and hence has been corrected.

Cyril Chemparathy bcd6a1c695 Davinci: iotable based ioremap() interception
This patch allows for a more flexible ioremap() interception based on iotable
contents.

With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized.  Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.

 - machine definitions directly point to cp_intc_init() or davinci_irq_init()

Cyril Chemparathy c78a5bc2e7 Davinci: watchdog reset separation across socs
The earlier watchdog reset mechanism had a couple of limitations.  First, it
embedded a reference to "davinci_wdt_device" inside common code.  This
forced all derived platforms (da8xx and tnetv107x) to define such a device.
This also would have caused problems in including multiple socs in a single
build due to symbol redefinition.

With this patch, davinci_watchdog_reset() now takes the platform device as an
argument.  The davinci_soc_info struct has been extended to include a reset
function and a watchdog platform_device.  arch_reset() then uses these
elements to reset the system in a SoC specific fashion.
