The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

So far we've enabled pull-up and pull-down resistors on GPIOs using a
pinctrl node. Now that the GPIO binding allows for a flag to declare this,
let's switch to it.
This brings us closer to removing all the GPIO pinctrl nodes, which will in
turn allow us to switch the pinctrl strict mode on.

While the USB PHY Device Tree mandates that the name of the VBUS detect pin
should be usb0_vbus_det-gpios, a significant number of device tree use
usb0_vbus_det-gpio instead.
This was functional because the GPIO framework falls back to the gpio
suffix that is legacy, but we should fix this.

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.

Some GPIO pinctrl nodes cannot be easily removed, because they would also
change the pin configuration, for example to add a pull resistor or change
the current delivered by the pin.
Those nodes still have underscores and unit-addresses in their node names
in our DTs, so adjust their name to remove the warnings. Use that occasion
to also fix some poorly chosen node-names.

The I2C's, MMC0 and EMAC controllers have only one muxing option in the
SoC. In such a case, we can just move the muxing into the DTSI, and remove
it from the DTS.

All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.
In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.

As part of our effort to move pinctrl/GPIO interlocking into the
driver where it belongs, this patch drops the definition and usage
of the mmc0_cd_pin_reference_design pinmux setting for the default
mmc0 card detect GPIO pin.

The FSF address triggers a warning on checkpatch, saying that the FSF
license is already present in the Linux source code, and that it has

Add UART aliases and stdout-path property for all the Allwinner boards so that
we won't have to rely on the bootargs' console= value, while working with
legacy bootloaders.
While we're at it, also remove the mentions of earlyprintk in the bootargs,
that will remove our default bootargs entirely, and allow the kernel to boot on
a system even if DEBUG_LL is configured for another system.
