Hello,

This patch series contains some core plat-s5p fixes, required for both
plat-s5pc1xx cleanup series as well as patches that add Samsung Aquila
board support. This patch series has been rebase onto next-samsung git
tree.

This is a resend of these patches. They were already posted as a part of
other patch series. However most of them are outdated and do not apply
onto the current next-samsung tree.

The series contain the following patches:

[PATCH 1/3] ARM: Samsung: fix broken timer irq base
[PATCH 2/3] ARM: Samsung: move common I2C0 device helpers to machine directories
[PATCH 3/3] ARM: Samsung: move driver strength gpio configuration helper to common dir

Timer interrupts range was defined as 43-47, what overlaps with VIC0 range
(32-64). This was caused probably by a typo while the common interrupts
definition was refactored. This patch moves timer interrupt range to safe
area of 11-15 (just before uart range).

I2C0 device helper depend on GPIO pin defines that are SoC specific.
This patch copies the dummy i2c0 setup code to the respective mach-s5p*
directories, so each SoC will be able to implement using its own
defines.

Driver strength parameter can be changed not only on S5PC100 but also
on S5PV210/S5PC110 platforms, so move the helper functions to the common
plat-samsung directory.

87aef30e (Atul Dahiya 2010-01-29 09:08:28 +0900 82) #define S5P_TIMER_IRQ(x)    S5P_IRQ(11 + (x))

is the one to blame here.

    ARM: S5P: Change S5P_TIMER_IRQ based to 11 for SAMSUNG S5P series.
    
    Currently, S5P_TIMER_IRQ is based at the end of VICs. This patch changes
    the S5P_TIMER_IRQ base from end of VICs to 11 in ISA IRQ space.
    No of VICs varies between SOCs. This causes an exception on S5P6442.

So it looks like this was intended to re-use the ISA interrupt range
but didn't get it quite right.

Yes, right.

Looks good except header of mach-s5pv210/setup-i2c0.c

And as I reviewed, how about re-submitting this patch with c100 i2c moving?

One more, moving from plat-s5p/ is better than creating.
