Add support for the Bananapi R2 (BPI-R2) development board from
BIPAI KEJI. Detailed hardware information for BPI-R2 which could be
found on http://www.banana-pi.org/r2.html



The patch added nodes into the SoC-level file mt7623.dtsi such as CPU OPP
table and thermal zone treating CPU as one of cooling devices and also
added nodes into board-level file mt7623n-bananapi-bpi-r2.dts such as
MediaTek GMAC, MT7530 Switch, the crypto engine, USB, IR, I2S, I2C, UART,
SPI, PWM, GPIO keys, GPIO LEDs and PMIC LEDs. As to the other missing
hardware and peripherals, they would be added and integrated continuously.

There are 2 versions of the MT7623 SoC, the one is MT7623N and the other
is MT7623A.  MT7623N is almost identical to MT7623A but has some
additional multimedia features. The reference boards are available as
NAND or MMC and might have a different ethernet setup. In order to reduce
the duplication of devicetree code we add an intermediate dtsi file for
these reference boards. Additionally MediaTek pointed out, that the EVB
is yet another board and the board in question is infact the RFB. Take
this into account while renaming the files.

MediaTek produces various PMICs. Which one is used depends on the actual
circuit design. Instead of adding the correct PMIC node to every dts file
we instead add a new intermediate dtsi file which adds the PMIC node. For
those boards with the same PMIC, the intermediate mt6323.dtsi could be
reused to save more redundant nodes created on each board device-tree
files.

The cm-fx6 module has an on-board AW-NH387 WiFi/BT module which is
based on Marvell's SD8787 chip and is connected to the usdhc1
controller.

Unfortunately, the chip gets unresponsive if the Bluetooth AMP
(Alternate Mac/Phy) function gets probed but the loaded firmware
doesn't support it. For instance, this is the case for the most
recent firmware in linux-firmware (Version 14.66.35.p52).

Thus, just add the required nodes but leave the usdhc1 node disabled
explicitly. Users who disabled the Bluetooth (AMP) support of their
OS can then conveniently enable WiFi (or even plain Bluetooth) support
with a simple device tree overlay/bootloader configuration.

0x0000000f4000-0x0000004f4000 : "conf"

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.

But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.

So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

The Linksys WRT3200ACM (Rango) is the lates Armada-385 based router in
the Linksys WRT AC Series which got released in October 2016.

Key differences to the earlier Armada-385 based devices in the series is
a bigger flash chip, next generation wireless modules (Marvell 88W8964)
in the mini pcie slots as well as a Marvell SD8887. Finally the CPU is
clocked at 1866 GHz by default.

The file armada-385-linksys-rango.dts is loosly based off of a DTS
authored by Imre Kaloz.

As Rango is part of the armada-385-linksys family of boards use the
armada-385-linksys.dtsi as basis. As for functional differences to Imre
Kaloz dts, the wlan LEDs aren't connected to the expander chip pca9635
but directly to GPIOs. Then mpp47 controls the USB2.0 port and not the
USB3.0 port, so use the correct GPIO mpp44 for it. Finally use
non-removable instead of broken-cd with the sdhci node to avoid polling.

Other changes can be categorized as just cleanup / reorganization due to
using the armada-385-linksys.dtsi.
