Stefan Agner 4ee5ad0ca8 ARM: dts: vf-colibri: disable write-protection for SD-card
The Colibri standard does not define a pin for SD-Card write-
protection. Use the disable-wp property to indicate that there
is no physical WP line present.

Stefan Agner 47b06e6ef5 ARM: dts: vf-colibri: add basic supply regulators
Colibri modules need to be powered using the power pins 3V3 and
AVDD_AUDIO. Add fixed regulators which represent this power rails.
Potentially, those power rails could be switched on a carrier
board. A carrier board device tree could add a own regulator with
a GPIO, and reference that regulator in a vin-supply property of
those new module level system regulators.

Stefan Agner 5c35b778bf ARM: dts: vf-colibri: assign Ethernet clock explicitly
Assign Ethernet clock parents explicitly. The Colibri VF61
uses the 50MHz Ethernet clock provided by PLL5.

The Vybrid SoC has two ethernet interfaces (fec0 and fec1) which
use the same clock source (VF610_CLK_ENET). Therefore this parent
configuration affects multiple consumer devices and need to be
specified in the clock provider node.

Stefan Agner 9f3440ddf4 ARM: dts: vf610-colibri: relicense vf*colibri* under GPLv2/X11
GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license.

The consensus is that a GPL/X11 dual-license should allow all necessary
uses, so relicense the vf*colibri* files to this combination.

CCs were acquired using:
git shortlog -sne --no-merges arch/arm/boot/dts/vf*colibri*

Stefan Agner 2afa06cbf1 ARM: dts: vf-colibri: add CAN support
Add Colibri standard pinmux for FlexCAN controller instances. CAN
is not a standard Colibri feature, but the datasheet predefines
pins which provide CAN (compatible across some modules). Hence,
add the pinmux on module level.

Stefan Agner 654252659e ARM: dts: vf-colibri: enable NAND flash controller
Enable NAND access by adding pinmux and NAND flash controller node
to device tree. The NAND chips currently used on the Colibri VF61
requires 8-bit ECC per 512 byte page, hence specify 32-bit ECC
strength per 2k page size.

Cory Tusar aa5fec2db1 ARM: dts: vf610: Nomenclature fixup for PTC12 pin used in RMII mode.
This commit includes a minor nomenclature fixup for boards based on the
Freescale VF610 SoC and which make use of the alternate "RMII1_RXD1"
functionality for pin PTC12.  This brings the macro name in-line with
both the datasheet and other similar macros.

Stefan Agner 767139540c ARM: vf610: use zero based naming for GPIO nodes
On Vybrid, all peripherals are numbered starting with zero,
including the GPIO and PORT module. However, the labels of the
corresponding device tree nodes start with one, which is confusing.
Fix that by renaming the labels of the gpio nodes in the device
tree.

Stefan Agner eddb00fa12 ARM: dts: vf-colibri: add CLKOUT pin to pinctrl of FEC1
On the Colibri module, the RMII clock for the Ethernet PHY is
generated by the SoC. This patch adds that missing pin to the
pinctrl of FEC1. Because the boot loader initializes this pin,
ethernet worked even without this pin so far.
