4b93521587 ARM: dts: dra7-evm: add evm_3v3_sd regulator
Add a node for evm_3v3_sd using onboard pcf GPIO expander which feeds
on to mmc vdd.

Update mapping for vmmc-supply and vmmc_aux-supply.
evm_3v3_sd supplies to SD card vdd, and ldo1 to sdcard i/o lines.

2acb5c301e ARM: dts: dra7x-evm: Prevent glitch on DCAN1 pinmux
Driver core sets "default" pinmux on on probe and CAN driver
sets "sleep" pinmux during register. This causes a small window
where the CAN pins are in "default" state with the DCAN module
being disabled.

Change the "default" state to be like sleep so this glitch is
avoided. Add a new "active" state that is used by the driver
when CAN is actually active.

5c73cc4b6c ARM: DT updates for v4.1
As always, this tends to be one of our bigger branches. There are lots of
 updates this release, but not that many jumps out as something that needs
 more detailed coverage. Some of the highlights are:
 
 - DTs for the new Annapurna Labs Alpine platform
 - More graphics DT pieces falling into place on Exynos, bridges, clocks.
 - Plenty of DT updates for Qualcomm platforms for various IP blocks
 - Some churn on Tegra due to switch-over to tool-generated pinctrl data
 - Misc fixes and updates for Atmel at91 platforms
 - Various DT updates to add IP block support on Broadcom's Cygnus platforms
 - More updates for Renesas platforms as DT support is added for various IP
   blocks (IPMMU, display, audio, etc).

ee327179b9 Wireless and omap changes to make wl12xx driver to use device tree

 - Add device-tree support to the wlcore (wl12xx/wl18xx) driver.
 
 - Update the current users to use the bindings instead of pdata-quirks.
 
 - Finally, remove the deprecated wl12xx_platform_data struct
 
 Note that da850 board file code that still uses the platform data,
 but we have da850.dtsi that can be used instead. So it was decided
 that we should try to remove the wl12xx support from the da850
 board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
 the last patch in the series, the last patch can be simply reverted
 if needed.
 
 As this series touches quite a bit of arch code, it was suggested
 by Kalle Valo <kvalo@codeaurora.org> that the whole series should
 be merged via the arm-soc tree.

a7b0aa1932 ARM: dts: dra7x-evm: beagle-x15: Fix USB Peripheral
Now that we have EXTCON_USB_GPIO queued for v4.1, revert
commit addfcde7c4 ("ARM: dts: dra7x-evm: beagle-x15: Fix USB Host")

On these EVMs, 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.

783d31863f irqchip: crossbar: Convert dra7 crossbar to stacked domains
Support for the TI crossbar used on the DRA7 family of chips
is implemented as an ugly hack on the side of the GIC.

Converting it to stacked domains makes it slightly more
palatable, as it results in a cleanup.

Unfortunately, as the DT bindings failed to acknowledge the
fact that this is actually yet another interrupt controller
(the third, actually), we have yet another breakage. Oh well.

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

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.

 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS

 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down

weak PULLs.

The second CAN port cannot be used without hardware modification
so we don't enable the second port.

395b23ca57 ARM: dts: dra7-evm: Keep all VDD rails always-on
DRA7 Data Manual (SPRS857L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified
in the Section 5.2, Recommended Operating Conditions".

This implies that all unused voltage rails for Vayu can never be
switched off even if the hardware blocks inside that voltage domain is
unused. Switching off these unused rails may result in stability issues
on other domains and increased leakage and power-on-hour impacts.

J6eco-evm dts file already considers this, however j6evm-dts file needs
to be fixed to consider this constraint of the SoC.

c7cc9ba11f ARM: dts: dra7-evm: Add vtt regulator support
DRA7 evm REV G and later boards uses a vtt regulator for DDR3
termination and this is controlled by gpio7_11. This gpio is
configured in boot loader. gpio7_11, which is only available only on
Pad A22, in previous boards, is connected only to an unused pad on
expansion connector EXP_P3 and is safe to be muxed as GPIO on all
DRA7-evm versions (without a need to spin off another dts file).

Since gpio7_11 is used to control VTT and should not be reset or kept
in idle state during boot up else VTT will be disconnected and DDR
gets corrupted. So, as part of this change, mark gpio7 as no-reset and
no-idle on init.

e120fb4596 ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on
After clarification from the hardware team it was found that
this 1.8V PHY supply can't be switched OFF when SoC is Active.

Since the PHY IPs don't contain isolation logic built in the design to
allow the power rail to be switched off, there is a very high risk
of IP reliability and additional leakage paths which can result in
additional power consumption.

The only scenario where this rail can be switched off is part of Power on
reset sequencing, but it needs to be kept always-on during operation.

This patch is required for proper functionality of USB, SATA
and PCIe on DRA7-evm.

- adds DT binding for Micron NAND Flash (MT29F2G16AADWP) present on dra7-evm
*Important*
	On DRA7 EVM, GPMC_WPN and NAND_BOOTn are controlled by DIP switch
	So following board settings are required for NAND device detection:
	SW5.9 (GPMC_WPN) = LOW
	SW5.1 (NAND_BOOTn) = HIGH
