b3b9d7ca32 dm: tegra: cros_ec: Enable Chrome OS EC on Nyan-big
Enable the EC and keyboard, using the SPI bus.

The EC driver requires a particular format and a deactivation delay. Also
U-Boot does not support interrupts.

For now, adjust the device tree to comply. At some point we should tidy
this up to support interrupts and make tegra and exynos use the same setup.

09cfa8ee6a colibri_vf: Enable board specific USB initialisation for USB pen gpio
Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".

8b1ba94151 sunxi: Sync dts files with the linux kernel
Copy over all the latest dts changes from mripard/sunxi/dt-for-4.2 ,
this gives us a proper dtsi file for the A33 rather then abusing
sun8i-a23.dtsi for this.

And this replaces our minimal (dummy) sun7i-a20-mk808c and

2c23da06ba sunxi: Add new Mele_A1000G_quad defconfig
The Mele A1000G-quad and the Mele M9 have the same PCB, sofar we've been
using the same defconfig (and dts on the kernel side) for both models.
Unfortunately this does not work for the otg controller, on the M9 this
is routed to a micro-usb connector on the outside, while as on the
A1000G-quad it is connected to an usb to sata bridge.

This commit adds a new defconfig for the Mele-A1000G-quad to allow using
different otg controller settings on the 2 boards.

7afebb5b29 sunxi: usb_phy: Swap check for disconnect threshold
Before this commit the code for determining the disconnect threshold was
checking for sun4i or sun6i assuming that those where the exception and
that newer SoCs use a disconnect threshold of 2 like sun7i does.

But it turns out that newer SoCs actually use a disconnect threshold of 3
and sun5i and sun7i are the exceptions, so check for those instead.

Here are the settings from the various Allwinner SDK sources:
 sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
 sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2);
 sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun8i-h3:  USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
 sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);

Note this commit makes no functional changes for sun4i - sun7i, and
changes the disconnect threshold for sun8i to match what Allwinner uses.

One disadvantage of commit a26cd04920 (arch: Make board selection

As PH1-Pro4 is the main stream of UniPhier SoC family, rip off the
"optional" again in favor of PH1-Pro4 as the default SoC.
