0c8a507fd2 ARM: dts: dra7-evm: add pinmux configuration for mmc1/2
Add pinmux configuration for SD card slot and eMMC device
found on TI's DRA74x EVM.

Only the default modes are supported. For higher speed modes
(UHS and HS200) to function, we need full fledged IODelay support
in kernel. IODelay support is yet to be added.

d888e9d783 ARM: dts: dra7-evm: Remove pinmux configurations for erratum i869
Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.

Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence).

DCAN pinmux is retained in this patch. MMC pinmux is missing from
the dra7-evm.dts file and the board is relying on configuration done
by bootloader. A subsequent patch will add MMC pinmux configuration.

A side-effect of this patch is that NAND support is removed. NAND
pins clash with VOUT3 on DRA7-EVM. U-Boot selects VOUT3 over NAND
as per TI EVM application needs.

626180785f ARM: dts: dra7x: Remove QSPI pinmux
DRA7 family of processors from Texas Instruments, have a hardware module
called IODELAYCONFIG Module which is expected to be configured. This
block allows very specific custom fine tuning for electrical
characteristics of IO pins that are necessary for functionality and
device lifetime requirements. IODelay module has it's own register space
with registers to configure various pins.

According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1]
section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE),
when operating a pad in certain mode, Virtual/Manual IO Timing Mode must
also be configured to ensure that IO timings are met (DELAYMODE and
MODESELECT fields of pad's IODELAYCONFIG module register). According to
section 18.4.6.1.7 Isolation Requirements of above TRM, when
reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a
potential for a significant glitch on the corresponding IO. It is hence
recommended to do this with I/O isolation (which can only be done in
initial stages of bootloader). QSPI is one such module that requires
IODELAY configuration. So, this patch removes the pinmux for
QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot)
and cannot be done in kernel.

Users should migrate to U-Boot v2016.05-rc1 or higher.

54d03c5d8b ARM: dts: AM57xx/DRA7: Update SoC voltage rail limits to match data sheet
As per the data sheet starting from SPRUHQ0H (Nov 2015 - Latest[1]),
VDD_CORE can vary from 0.85v to 1.15v for AVS class0. VDD GPU/DSP
et.al. can range from 0.85v to 1.25V with AVS class0

Since dynamic voltage scaling is disabled for DRA7/AM57xx SoCs for
all SoC rails other than MPU, the bootloader is responsible for
setting up the AVS class0 voltage, however, with wrong voltage machine
constraints in dtb, regulator framework will lower the voltage below
the required voltage levels for certain samples in production flow.
This can cause catastrophic failures which can be pretty hard to
identify.

Update board files which don't match required specification.

3a1de80824 ARM: dts: dra7xx: Fix compatible string for PCF8575 chip
The binding definition for the PCF857x GPIO expanders doesn't mention
a "ti,pcf8575" compatible string.  This is apparently because TI is
only a second source - there is no functional difference between
PCF8575 chips manufactured by TI and NXP, and the same board might be
populated with either depending on availability.

This is not a problem in practice because the I2C core uses
of_modalias_node() before matching drivers and this strips the
manufacturer name.

connected to the card detect line. On card removal, omap_hsmmc
driver does a regulator_disable causing card detect line to be
pulled down. This raises a card insertion interrupt and once the
MMC core detects there is no card inserted, it does a
regulator disable which again raises a card insertion interrupt.
This happens in a loop causing infinite MMC interrupts.

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).

 - 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.

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.

DRA7 Data Manual (SPRS857L - August 2014) section 4.1.1 states: "All
unused power supply balls must be supplied with the voltages specified

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.
