ARM i.MX SoC updates for next
Mostly clock related updates, most notably the conversion of
i.MX31 to a DT based lookup.

ARM: clk-imx35: Fix build warnings with W=1
ARM: imx27: add a clock gate to activate SPLL clock
ARM: mx31: Replace clk_register_clkdev with clock DT lookup
ARM: clk-imx31: Add dummy clock

into next/cleanup
From Rob Herring:
Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas
Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
and adapted to use the new infrastructure. All DT enabled platforms
using GIC and VIC are converted over to use the new irqchip_init.

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register(). Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.

Since commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access
secure registers) ARM_ERRATA_743622/751472 depends on !ARCH_MULTIPLATFORM.
Since imx has been converted to multiplatform, the following warning happens:
$ make imx_v6_v7_defconfig
warning: (SOC_IMX6Q && ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC) selects
ARM_ERRATA_751472 which has unmet direct dependencies (CPU_V7 &&

Recommended approach is to remove ARM_ERRATA_743622/751472 from being selected
by SOC_IMX6Q and apply such workarounds into the bootloader.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree.
It turned out that the system does not work properly when the MIPI/HSP
clocks are enabled, but the IPU clock is disabled. This happens when
IPU support is disabled. In this case the IPU clock gets disabled when
the clock framework turns off unused clock in a late_initcall. This
is broken since:

| ARM i.MX5: switch IPU clk support to devicetree bindings
|
| The i.MX5 clk support has platform based clock bindings for the
| IPU. IPU support is devicetree only, so move them over to devicetree
| based bindings. Also, enable MIPI clocks which do not have a device
| associated with, but still need to be enabled to do graphics on
| i.MX51.
This patch fixes this by setting some reserved bits in the CCM as recommended
in the reference manual.

Pull ARM SoC device tree conversions and enablement from Olof Johansson:
"Continued device tree conversion and enablement across a number of
platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms
have seen pinctrl-via-devicetree conversions for simpler
multiplatform. Tegra is adding data for new devices/drivers, and
Exynos has a bunch of new bindings and devices added as well.
So, pretty much the same progression in the right direction as the
last few releases."

Now that the additional enable bits in the enet PLL are handled
as gates, the gate_mask is identical for all plls. Remove the
gate_mask from the code and use the BM_PLL_ENABLE bit for
enabling/disabling the PLL.

In current code the ethernet PLL is not handled correctly. The PLL runs at 500MHz
and has different outputs. Only the enet reference clock is implemented. This
patch changes the PLL so that it outputs 500MHz and adds the additional outputs
as dividers. This now matches the datasheet which says:
> This PLL synthesizes a low jitter clock from 24 MHz reference clock.
> The PLL outputs a 500 MHz clock. The reference clocks generated by this PLL are:
> • Ref_PCIe = 125 MHz
> • Ref_SATA = 100 MHz
> • Ref_ethernet, which is configurable based on the PLL_ENET[1:0] register field.

The i.MX5 clk support has platform based clock bindings for the
IPU. IPU support is devicetree only, so move them over to devicetree
based bindings. Also, enable MIPI clocks which do not have a device
associated with, but still need to be enabled to do graphics on
i.MX51.

The MIPI interface has to be initialized for proper IPU support.
The MIPI officially is not supported, but still needs initialization.
This patch adds this to the SoC startup as all it does is poking
some magic values into registers for which we do not have documentation.

During the clock conversion for mx27 the "per4_gate" clock was missed to get
registered as a dependency of mx2-camera driver.
In the old mx27 clock driver we used to have:
DEFINE_CLOCK1(csi_clk, 0, NULL, 0, parent, &csi_clk1, &per4_clk);
,so does the same in the new clock driver

The i.MX27 clock tree can either be driven from a 26MHz oscillator
or from a 32768Hz oscillator. The latter was not properly implemented,
the mux between these two pathes was missing. Add this mux and while
at it rename the 'prem' (premultiplier) clk to 'fpm' (Frequency
Pre-Multiplier) to better match the datasheet.

This is to prepare addition of m2m-emmapp driver otherwise
IMX_HAVE_PLATFORM_MX2_CAMERA must be declared even if only Post-Processor is
needed.
IMX_HAVE_PLATFORM_MX2_EMMA define has been added.
Changes since v1:
- Add "select IMX_HAVE_PLATFORM_MX2_EMMA" for MACH_IMX27_VISSTRIM_M10 platform
due to pending patch in linux-media tree that will call
imx27_add_mx2_emmaprp().

imx6q gets 5 uart ports in total. Different board design may choose
different port as debug uart. For example, imx6q-sabresd uses UART1,
imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than
bloating DEBUG_LL choice list with all these uart ports, the patch
introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number
when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

This completes the list of clock gates on the i.MX25. There are
several clocks marked as reserved in the datasheet, but nevertheless
used in the Freescale kernel. Add some comments to their positions
and add 'reservedx' entries to the clk enum. This way we can replace
them with the real names should we need them later. Adding the reserved
entry names will help us keeping the clk numbers when moving to devicetree.
