5b7897db00 ARM: EXYNOS: Avoid early use of of_machine_is_compatible()
The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process.  It also probably meant that the exynos5440
failed to use the proper iotable.  Switch to use
of_flat_dt_is_compatible() in both of these cases.

The failure I was seeing in exynos5250 because of this was:
  Division by zero in kernel.

ea3aacf5f2 ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event device
The SP804 driver statically initialises the cpumask of the clock event
device to be cpu_all_mask, which is derived from the compile-time
constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback
on the irq_chip, because the common timer code fails to identify the
device as cpu-local and ends up treating it as a broadcast device
instead.

This patch fixes the problem by using cpu_possible_mask at runtime,
which will correctly represent the possible CPUs when SMP_ON_UP is being
used.

80515a5a2e ARM: SPEAr3xx: shirq: simplify and move the shared irq multiplexor to DT
SPEAr3xx architecture includes shared/multiplexed irqs for certain set
of devices. The multiplexor provides a single interrupt to parent
interrupt controller (VIC) on behalf of a group of devices.

There can be multiple groups available on SPEAr3xx variants but not
exceeding 4. The number of devices in a group can differ, further they
may share same set of status/mask registers spanning across different
bit masks. Also in some cases the group may not have enable or other
registers. This makes software little complex.

Present implementation was non-DT and had few complex data structures to
decipher banks, number of irqs supported, mask and registers involved.

This patch simplifies the overall design and convert it in to DT.  It
also removes all registration from individual SoC files and bring them
in to common shirq.c.

Also updated the corresponding documentation for DT binding of shirq.

expect from dt to provide this pinctrl states and phandler otherwise it

To remove this warning message pass default state with null phandler to uart
pins in device node (In our case all the pins are configured in default states
so we pass null phandler to pins).

5010192d5a ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above
Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

ce7b175656 ARM: 7585/1: kernel: fix nr_cpu_ids check in DT logical map init
If a kernel is configured with a DT containing more /cpu nodes than
nr_cpu_ids, the number of cpus must be capped in the DT parsing
code. Current code carries out the check, but fails to cap the
value and the check is executed after the cpu logical index is used,
which can lead to memory corruption due to index overflow.

This patch refactors the check against nr_cpu_ids and move it before
any computed index is used in the parsing code.

9f3410ff21 arm: mvebu: fix address decoding armada_cfg_base() function
The armada_cfg_base() function returns the base address of the
registers that allow to configure the decoding for a particular
address window. On Armada 370/XP, the lower windows have more
configuration registers (4 registers) than the higher windows (2
registers). This armada_cfg_base() takes this into account by doing a
different offset calculation depending on the window number, but this
offset calculation was wrong for the higher windows.

Even though we were not using high window numbers until now (only
window 0 is used to map the BootROM, needed for SMP), we use this
function at boot time to disable all windows to ensure that nothing
remains intialized from what the bootloader has done.

Unfortunately, the U-Boot on the OpenBlocks AX3-4 uses a window with a
high number (above 8) to remap the BootROM. And then when the kernel
boots, it remaps the BootROM in window 0. Normally, this is not a
problem, because all windows have previously been disabled. Except
that due to our wrong offset calculation, the windows with high
numbers were not properly disabled, leading to the BootROM being
mapped twice. The visible result of this bug was that the kernel was
unable to get the second CPU started on the OpenBlocks AX3-4
platform. With this fix, all windows are properly cleared at boot
time, the BootROM is remapped only once in window 0, and the second
CPU boots fine.

Thanks a lot to Lior Amsamlen <alior@marvell.com> for his help in
debugging this problem.

Strictly speaking, this bug was introduced in 3.7, but since the only
platforms supported in 3.7 were Armada 370 and Armada XP, and there
was anyway no SMP support at this time, it isn't really worth the
effort to push this patch in 3.7.

7a04092c73 ARM i.MX6: Fix ethernet PLL clocks
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.

0d2c9f0517 IXP4xx: use __iomem for MMIO
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not

Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.

c567b0584c ARM: OMAP2+: omap_device: Correct resource handling for DT boot
When booting with DT the OF core can fill up the resources provided within
the DT blob.
The current way of handling the DT boot prevents us from removing hwmod data
for platforms only suppose to boot with DT (OMAP5 for example) since we need
to keep the whole hwmod database intact in order to have more resources in
hwmod than in DT (to be able to append the DMA resource from hwmod).

To fix this issue we just examine the OF provided resources:
If we do not have resources we use hwmod to fill them.
If we have resources we check if we already able to recive DMA resource, if
no we only append the DMA resurce from hwmod to the OF provided ones.

In this way we can start removing hwmod data for devices which have their
resources correctly configured in DT without regressions.

This patch adds all currently available Dove boards, including a DT-enabled

Finally, sdhci driver for Dove, mv_cesa, GPIO LEDs, and highmem support is
added.

0a0d628573 ARM - OMAP: ads7846: fix pendown debounce setting
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

07f645df9f arm: orion5x: convert 'LaCie Ethernet Disk mini v2' to Device Tree
This commit converts the 'LaCie Ethernet Disk mini v2' board to the
Device Tree. All devices that have existing Device Tree bindings are
converted over to the Device Tree, the other devices remain
instantiated in the old way, until the respective drivers get the
needed Device Tree bindings.

1bffb4a872 arm: orion5x: basic Device Tree support
This commit adds basic DT support for the Orion5x SoC family. It adds
an orion5x.dtsi description of the Orion5x SoC as well as the needed
DT_MACHINE structure to support boards converted to DT in the future.

So far, the Device Tree contains the interrupt controller, the GPIO
bank, the UART controllers, the SPI controller, the watchdog, the SATA
controller, the I2C controller and the cryptographic engine.

9973978614 arm: orion5x: mechanical defconfig update
This commit is a simple mechanical update of the orion5x_defconfig
file to the current kernel (i.e, just 'make orion5x_defconfig; make
savedefconfig'). Doing this update allows to more easily separate
DT-related configuration changes in the following patches.
