Marek Szyprowski 995b528ad2 ARM: SAMSUNG: Add chained enrty/exit call to timer interrupt handler
This patch adds chained IRQ enter/exit functions to timer
interrupt handler in order to function correctly on primary
controllers with different methods of flow control.

Kukjin Kim b8a297d3f8 ARM: SAMSUNG: Fix Section mismatch in samsung_bl_set()
WARNING: vmlinux.o(.text+0xf47c): Section mismatch in reference from the function samsung_bl_set() to the (unknown reference) .init.data:(unknown)
The function samsung_bl_set() references
the (unknown reference) __initdata (unknown).
This is often because samsung_bl_set lacks a __initdata
annotation or the annotation of (unknown) is wrong.

MyungJoo Ham f462904ef1 ARM: SAMSUNG: use regulator VDD for ADC
This patch allows the Samsung ADC driver to enable VDD regulator
at probe and resume and to disable at exit and suspend.
In a platform where ADC's VDD regulator is not "always-on", this
control is required although this patch does not provide fine-grained
power control (turning on the regulator only when being accessed).

However, if VDD regulator ("vdd" for the adc device) is not provided,
the regulator control will not be activated because there are platforms
that do not provide regulator for ADC device.

arch_initcall has been modified to module_init in order to allow
regulators to be available at probe.

Simon Guinot 659fb32d1b genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd)
This fixes a regression introduced by e59347a "arm: orion:
Use generic irq chip".

Depending on the device, interrupts acknowledgement is done by setting
or by clearing a dedicated register. Replace irq_gc_ack() with some
{set,clr}_bit variants allows to handle both cases.

Note that this patch affects the following SoCs: Davinci, Samsung and
Orion. Except for this last, the change is minor: irq_gc_ack() is just
renamed into irq_gc_ack_set_bit().

For the Orion SoCs, the edge GPIO interrupts support is currently
broken. irq_gc_ack() try to acknowledge a such interrupt by setting
the corresponding cause register bit. The Orion GPIO device expect the
opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used.

Tested on Network Space v2.

Russell King 29cb3cd208 ARM: pm: allow suspend finisher to return error codes
There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.

Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack.  Also omit the tlb flush as no
changes to the page tables will have happened.

Russell King 2c74a0cefa ARM: pm: hide 1st and 2nd arguments to cpu_suspend from platform code
The first and second arguments shouldn't concern platform code, so
hide them from each platforms caller.

Russell King e7089da956 ARM: pm: samsung: move cpu_suspend into C code
Move the call to cpu_suspend into C code, and noticing that all the
s3c_cpu_save implementations are now identical, we can move this
into the common samsung code.

Russell King 14cd8fd574 ARM: pm: move cpu_init() call into core code
As we have core code dealing with CPU suspend/resume, we can
re-initialize the CPUs exception banked registers via that code rather
than having platforms deal with that level of detail.  So, move the
call to cpu_init() out of platform code into core code.

Joe Perches 28f65c11f2 treewide: Convert uses of struct resource to resource_size(ptr)
Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

Boojin Kim 470f229754 ARM: SAMSUNG: serial: Fix on handling of one clock source for UART
This patch fixes the way of comparison for handling of two or more
clock sources for UART.

For example, if just only one clock source is defined even though
there are two clock sources for UART, the serial driver does not
set proper clock up. Of course, it is problem.

So this patch changes the condition of comparison to avoid useless
setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
selection of source clock is not required.

In addition, since the Exynos4210 has only one clock source for UART
this patch adds the flag into its common_init_uarts().

Padmavathi Venna 457d4fe851 ARM: S5P64X0: Fix SPI platform device name
Changed the SPI platform device name from S5P6450 to S5P64x0 as it is
defined common for both S5p6440 and S5P6450 in dev-spi.c of S5P64x0.
