Signed-off-by: NMaxime Ripard <maxime.ripard@free-electrons.com>

The A10s and the A13 are very similar SoCs, the only difference being the
number of pins and the number of devices available (number of UARTs, EMAC only
in the A10s, etc.), and the clocks and pinctrl functions obviously.

Create a common DTSI that will be included by the A10s and A13 DTSI, that will
add their SoC differences in there.

On the Optimus board, all three USB hosts can be used.
HCI0 and HCI2 are available through the USB connector.
HCI1 is available with HSIC through 2 pins on the GPIO
expansion header.

This patch also adds a regulator for HCI2/USB3's VBUS.

Add support for the LinkSprite pcDuino 3 Nano board. This is a low-cost
Allwinner A20 board with Arduino-style GPIO headers; it features 1G RAM,
4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro USB socket for OTG and
another for power in, HDMI, SATA, 5V power for SATA devices, gigabit
Ethernet, an IR receiver, 3.5mm audio out and a MIPI camera connector.

For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano

Changes in v3:
- rename LEDs to pcduino3-nano:green:usr[12]
- remove optional features on Arduino headers (i2c2, spi0, uart2)

AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with
SS == 0 results in an invalid usermode state in which SS is apparently
equal to __USER_DS but causes #SS if used.

Work around the issue by setting SS to __KERNEL_DS __switch_to, thus
ensuring that SYSRET never happens with SS set to NULL.

This was exposed by a recent vDSO cleanup.

Fixes: e7d6eefa x86/vdso32/syscall.S: Do not load __USER32_DS to %ss

Pull intel drm fixes from Dave Airlie.

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/i915: vlv: fix save/restore of GFX_MAX_REQ_COUNT reg
  drm/i915: Workaround to avoid lite restore with HEAD==TAIL
  drm/i915: cope with large i2c transfers

Pull intel iommu updates from David Woodhouse:
 "This lays a little of the groundwork for upcoming Shared Virtual
  Memory support — fixing some bogus #defines for capability bits and
  adding the new ones, and starting to use the new wider page tables
  where we can, in anticipation of actually filling in the new fields
  therein.

  It also allows graphics devices to be assigned to VM guests again.
  This got broken in 3.17 by disallowing assignment of RMRR-afflicted
  devices.  Like USB, we do understand why there's an RMRR for graphics
  devices — and unlike USB, it's actually sane.  So we can make an
  exception for graphics devices, just as we do USB controllers.

  Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to
  persistent requests.  X2APIC_OPT_OUT was added to the spec as a nasty
  hack to allow broken BIOSes to forbid us from using X2APIC when they
  do stupid and invasive things and would break if we did.

  Someone noticed that since Windows doesn't have full IOMMU support for
  DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid
  initialising the IOMMU on the graphics unit altogether.

  This means that it would be available for use in "driver mode", where
  the IOMMU registers are made available through a BAR of the graphics
  device and the graphics driver can do SVM all for itself.

  So they started setting the X2APIC_OPT_OUT bit on *all* platforms with
  SVM capabilities.  And even the platforms which *might*, if the
  planets had been aligned correctly, possibly have had SVM capability
  but which in practice actually don't"
