Using the cd-inverted property is not useful when GPIOs are used as card
detects since the polarity can be specified with the usual
GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for
U-Boot developers, so migrate all sunxi boards away from cd-inverted.

The Cubietruck Plus has a Realtek RTL8211E RGMII PHY tied to the EMAC.
The AXP818 PMIC's regulators provide main power and secondary signaling
voltages to the PHY. The latter is always on, as it also supplies the
pingroup on the SoC, which has other uses.
The Bananapi M3 has a Realtek RTL8211E RGMII PHY tied to the EMAC.
The AXP818 PMIC's SW regulators provides power to the PHY.
This patch enables Ethernet with the EMAC on both these boards by
enabling the emac node and setting all the required properties.
A proper ethernet alias is added as well.

The WiFi side of the AP6330 WiFi/BT combo module is connected to
mmc1. There are also GPIOs for enable and interrupts. An external
clock from the AC100 RTC is also used.
Enable WiFi on this board by enabling mmc1 and adding the power
sequencing clocks and GPIO, as well as the chip's interrupt line.
For the WiFi module to correctly detect the frequency of its main
oscillator, the external low power clock must be set to 32768 Hz.
Their does not seem to be proper out-of-band interrupt support
for the BCM4330 chip within the AP6330 module. This part is left
out for now.

This patch adds device nodes for all the regulators of the AXP818 PMIC.
Sunxi common regulators are removed, and USB VBUS regulators are added.

The Cubietruck-plus has a GL830 USB-to-SATA bridge connected to EHCI0,
and a USB3503 HSIC USB 2.0 hub connected to EHCI1. The USB3503's I2C
control interface is not connected.
This patch enables both EHCI controllers, adds a device node for the
USB hub, and includes sunxi-common-regulators.dtsi for the VBUS
regulators. The existing reg_vcc3v3 is dropped as it is also available
in the set of common regulators. Other unused regulators are disabled.

The AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies
in one package sharing the serial bus (I2C/RSB) pins. One die is the
actual PMIC. The other is an AC100 codec / RTC combo chip.
This patch adds the device nodes for the AC100 chip to the Cubietruck
Plus device tree.

This patch enables the RSB controller and adds a device node for the
PMIC die to the Cubietruck Plus device tree. Since the AXP813 and
AXP818 are virtually identical, this patch uses the compatible string
for the former as a fallback.

The pinmux setting nodes all have an address element in their node
names, however the pinctrl node does not have #address-cells.
Rename the existing pinmux setting nodes and labels in sun8i-a83t.dtsi,
dropping identifiers for functions that only have one possible setting,
and using the pingroup name if the function is identically available on
different pingroups.

Cubietruck Plus is a A83T/H8 based development board. The board has
standard DDR3 SDRAM, AXP818 PMIC/codec, SD/MMC, eMMC, USB 2.0 host
via HSIC USB Hub, USB OTG, SATA via USB bridge, gigabit ethernet,
WiFi, headphone out / mic in, and various GPIO headers.
The board also has an EEPROM on i2c0 which holds the MAC address.
