ARM: dts: sun8i: a83t: Enable USB OTG controller on some boards
The Bananapi M3 and Cubietruck Plus both have USB OTG ports wired to the
SoC and PMIC in the same way, with the N_VBUSEN pin on the PMIC
controlling VBUS output, the PMIC's VBUS input for sensing VBUS, and
PH11 on the SoC for sensing the ID pin.

Enable OTG on both boards.

ARM: dts: sun8i: a83t: Enable PMIC power supplies on various boards
On the Bananapi M3 and Cubietruck Plus, the DC input jacks are wired to
the ACIN pins, which is represented by the AC power supply. Both boards
have connectors for LiPo batteries, which are represented by the battery
power supply.

The H8 Homlet is a set-top box design. The DC input jack is wired to the
ACIN pins, but there are no battery connectors.

Enable these power supplies in the device tree.

Linus Torvalds b7badd1d7a ARM: Device-tree updates
As usual, this is where the bulk of our changes end up landing each
 merge window.
 
 The individual updates are too many to enumerate, many many platforms
 have seen additions of device descriptions such that they are
 functionally more complete (in fact, this is often the bulk of updates
 we see).
 
 Instead I've mostly focused on highlighting the new platforms below as
 they are introduced. Sometimes the introduction is of mostly a fragment,
 that later gets filled in on later releases, and in some cases it's
 near-complete platform support. The latter is more common for derivative
 platforms that already has similar support in-tree.
 
 Two SoCs are slight outliers from the usual range of additions. Allwinner
 support for F1C100s, a quite old SoC (ARMv5-based) shipping in the
 Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A,
 a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at
 infrastructure/networking.
 
 TI updates stick out in the diff stats too, in particular because they
 have moved the description of their L4 on-chip interconnect to devicetree,
 which opens up for removal of even more of their platform-specific
 'hwmod' description tables over the next few releases.

Chen-Yu Tsai afdd273e26 ARM: dts: sunxi: Enable Broadcom-based Bluetooth for multiple boards
This patch adds the Bluetooth node, and the underlying UART node if it's
missing, to the board device tree file for several boards. The LPO clock
is also added to the WiFi side's power sequencing node if it's missing,
to correctly represent the shared connections. There is also a PCM
connection for Bluetooth, but this is not covered in this patch.

These boards all have a WiFi+BT module from AMPAK, which contains one or
two Broadcom chips, depending on the model. The older AP6210 contains
two, while the newer AP6212 and AP6330 contain just one, as they use
two-in-one combo chips.

The Bluetooth side of the module is always connected to a UART on the
same pingroup as the SDIO pins for the WiFi side, in a 4 wire
configuration. Power to the VBAT and VDDIO pins are provided either by
the PMIC, using one or several of its regulator outputs, or other fixed
regulators on the board. The VBAT and VDDIO pins are shared with the
WiFi side, which would correspond to vmmc-supply and vqmmc-supply in the
mmc host node. A clock output from the SoC or the external X-Powers RTC
provides the LPO low power clock at 32.768 kHz.

All the boards covered in this patch are ones that do not require extra
changes to the SoC's dtsi file. For the remaining boards that I have
worked on, properties or device nodes for the LPO clock's source are
missing.

For the Cubietruck, the LPO clock is fed from CLK_OUT_A, which needs to
be muxed on pin PI12. This can be represented in multiple ways. This
patch puts the pinctrl property in the pin controller node. This is due
to limitations in Linux, where pinmux settings, even the same one, can
not be shared by multiple devices. Thus we cannot put it in both the
WiFi and Bluetooth device nodes. Putting it the CCU node is another
option, but Linux's CCU driver does not handle pinctrl. Also the pin
controller is guaranteed to be initialized after the CCU, when clocks
are available. And any other devices that use muxed pins are guaranteed
to be initialized after the pin controller. Thus having the CLK_OUT_A
pinmux reference be in the pin controller node is a good choice without
having to deal with implementation issues.

Corentin Labbe 5f8208f557 ARM: dts: sun8i: a83t: bananapi-m3: increase vcc-pd voltage to 3.3V
Since commit d7c5f68635 ("ARM: dts: sun8i: a83t: bananapi-m3: Add
AXP813 regulator nodes") my BPIM3 no longer works at gigabit speed.

With the default setting, dldo3 is regulated at 2.9v which seems
sufficient for the PHY but the aforementioned commit drops it to 2.5V
which is insufficient. Note that this behaviour is random for all BPIM3.
Some work with 2.5V, but some don't.

Finnaly, someone from Bananapi confirmed that this regulator must be set
to 3.3V.

ARM: dts: sun8i: a83t: Add CPU regulator supplies for A83T boards
The OPPs for the A83T CPU cores were added in v4.17 in commit 2db639d8c1
("ARM: dts: sun8i: a83t: add stable OPP tables and CPUfreq"), but board
level regulator supplies for the CPU clusters were only added for the
TBS-A711 tablet. This means the other A83T boards do not benefit from
voltage scaling, or worse, if the implementation does not scale the
frequency when the voltage is fixed, no benefit at all.

Add board level CPU cluster power supplies to all the A83T development
boards, so they can have proper dynamic CPU voltage and frequency scaling.
