Set the correct clkdev-name for the i2c clock.

It also get's rid of the ARCH_NR_GPIOS define on the rationale
that isn't an ARCH-wide setting anyway. If a device has two
pca953x devices, the reserved number will be wrong.

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Valentin Longchamp b7222631c3 mx31: rework of iomux support
This new implemenatation avoids that two physical pins are claimed by
the same driver (also with the the gpr hardware modes).
The gpio kernel lib is also called when a capable gpio pin is assigned
its gpio function.
The mxc_iomux_mode function is still here for backward compatibility but
should not be used anymore.

V2:

In the precendent revision, the iomux code was claiming a pin when its
hardware mode was changed. This was uncorrect: when the hardware mode is
changed, the pin must still be claimed through the iomux.

In order to have a pin working in mode hw2, we must fist issue the
mxc_iomux_set_gpr call and then the corresponding mxc_iomux_mode calls
with the FUNC mode (usually done with mxc_iomux_setup_multiple_pins).
The reverse calls must be done to fee the pins.

Guennadi Liakhovetski 5296b56d1b i.MX31: Image Processing Unit DMA and IRQ drivers
i.MX3x SoCs contain an Image Processing Unit, consisting of a Control
Module (CM), Display Interface (DI), Synchronous Display Controller (SDC),
Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter
(PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC).
CM contains, among other blocks, an Interrupt Generator (IG) and a Clock
and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are
supported over dmaengine and irq-chip APIs respectively.

IDMAC is a specialised DMA controller, its DMA channels cannot be used for
general-purpose operations, even though it might be possible to configure
a memory-to-memory channel for memcpy operation. This driver will not work
with generic dmaengine clients, clients, wishing to use it must use
respective wrapper structures, they also must specify which channels they
require, as channels are hard-wired to specific IPU functions.

Russell King dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Nicolas Pitre b5ee900258 [ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.
