In commit 87517d26d8 ("ARM: dts: dra7-evm: Add extcon nodes for USB")
we enabled Extcon USB gpio to tackle the USB ID pin and get
peripheral mode to work.
But the extcon-gpio-usb driver [1] didn't make it into v4.0
and this makes the USB driver defer probe indefinitely breaking
USB Host functionality.
As a temporary fix we remove the extcon handle from the
USB controller and add it back when the extcon driver
merges in v4.1.

On this EVM, the USB cable state has to be determined via the
ID pin tied to a GPIO line. We use the gpio-usb-extcon driver
to read the ID pin and the extcon framework to forward
the USB cable state information to the USB driver so the
controller can be configured in the right mode (host/peripheral).
Gets USB peripheral mode to work on this EVM.

As per the latest Data Manual, for newer samples,
the nominal voltage required for VDD_CORE at OPP_NOM can be
upto 1.06V which was 1.03V earlier.
Update the regulator max voltage constraint for SMPS7,
connected to VDD_CORE, to meet this requirement.

The board has 2 CAN ports but only the first one can be used.
Enable the first CAN port.
WAKEUP0 pin doesn't have INPUT enable bit so we just disable
weak PULLs.
The second CAN port cannot be used without hardware modification
so we don't enable the second port.

Add MMC1 and 2 nodes. MMC1 is SDcard and MMC2 is eMMC.
NOTE on MMC1 card detect: Ideally, we should be using in-built SDCD
support, but we dont have it yet. So, use the fact that control module
of DRA7 is setup such that no matter what mode one configures it, GPIO
option is always hardwired in - use GPIO mode for SDcard detection.
[peter.ujfalusi@ti.com]
The power line feeding the SD card is also used by other devices on the EVM.
Use generic name instead of mmc2_3v3 so when other devices want to use the
same regulator it will look a bit better.

DRA72-evm has a 256MB 16-bit wide NAND chip. Add
pinmux and NAND node.
The NAND chips 'Chip select' and 'Write protect' can be
controlled using DIP Switch SW5. To use NAND,
the switch must be configured like so:
SW5.1 (NAND_SELn) = ON (LOW)
SW5.9 (GPMC_WPN) = OFF (HIGH)

DRA72x-evm uses TPS65917 PMIC. Add the node.
NOTE: LDO2 is actually unused, but the usage if any is expected to be
between 1.8 to 3.3v IO voltage. So define the node.
NOTE: Interrupt used is crossbar number based.

DRA722 is part of DRA72x family which are single core cortex A15 devices
with most infrastructure IPs otherwise same as whats on the DRA74x family.
So move the cpu nodes into dra74x.dtsi and dra72x.dtsi respectively.
Also add a minimal dra72-evm dts file.
