This merges the Moxa and FTTMR010 device tree bindings into the
Faraday binding document to avoid confusion.

The FTTMR010 is the IP block used by these SoCs, in vanilla
or modified variant.

The Aspeed variant is modified such that it is no longer fully
register-compatible with FTTMR010 so for this reason it is not
listed with two compatible strings, instead just one.

Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset delay
greater than 1000ms are invalid.

During power off, after the GPIO pin has been asserted, some devices like
the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
clock gating and turning off regulators as to follow a graceful shutdown
sequence.

Therefore invent an optional power-off-delay-us DT binding for
mmc-pwrseq-simple, to allow us to support this constraint.

The datasheet and application note does not mention an allowed range for
the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set
lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with
T5x06 touch.

So, lacking a known lower limit, we increase the range for thresholds,
and set the lower limit to 0. The documentation is updated accordingly.

This patch allows the use of IRQ to notify the change of GPIO status
on MPC8xx CPM IO ports. This then allows to associate IRQs to GPIOs
in the Device Tree.

Ex:
	CPM1_PIO_C: gpio-controller@960 {
		#gpio-cells = <2>;
		compatible = "fsl,cpm1-pario-bank-c";
		reg = <0x960 0x10>;
		fsl,cpm1-gpio-irq-mask = <0x0fff>;
		interrupts = <1 2 6 9 10 11 14 15 23 24 26 31>;
		interrupt-parent = <&CPM_PIC>;
		gpio-controller;
	};

The property 'fsl,cpm1-gpio-irq-mask' defines which of the 16 GPIOs
have the associated interrupts defined in the 'interrupts' property.

Exynos LPASS requires some clocks to be enabled to make any access to its
registers. This patch adds code for handling such clocks. For current set
of registers it is enough to keep sfr0_ctrl clock enabled. Till now it
worked only because those clocks were enabled by bootloader and driver
probe() happened before they were disabled by clock core because of lack
of users. Handling those clocks is also needed to make it possible to
enable support for audio power domain.

This patch requires adding sfr0_ctrl clock to device tree.

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. To let the device tree describe which mode of operation is needed,
this patch introduces a new property "xpowers,master-mode".

There are various customizable parameters, so several variants for
this IP.  A generic compatible like "denali,denali-nand-dt" is
useless.  Moreover, there are multiple things wrong with this string.
(Refer to Rob's comment [1])

The "denali,denali-nand-dt" was added by Altera for the SOCFPGA port.
Replace it with a more specific string "altr,socfpga-denali-nand".
There are no users (in upstream) of the old compatible string.

The Denali IP on SOCFPGA incorporates the hardware ECC fixup engine.
So, this capability should be associated with the compatible.
