Describe device tree optional properties:

  * aspeed,reset-type = "cpu|soc|system|none"
     One of three different, mutually exclusive, values

	"cpu" : ARM CPU reset on signal
	"soc" : 'System on chip' reset
	"system" : Full system reset

     The value can also be set to "none" which indicates that no
     reset of any kind is to be done via this watchdog.  This assumes
     another watchdog on the chip is to take care of resets.

  * aspeed,external-signal - Generate external signal (WDT1 and WDT2 only)
  * aspeed,alt-boot - Boot from alternate block on signal

The watchdog IP block on Meson8 and Meson8m2 is already supported by the
existing meson-wdt driver. Meson8 uses the same register bits as Meson6,
while the newer Meson8m2 SoC uses the same register bits as Meson8b.

Currently watchdog support on Meson8 SoC already works because
meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a
separate compatible for Meson8 makes this more explicit though.

This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.

The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers.

This adds the audio plls (frac, pad and pmc) to the compatible list of
at91 clocks in DT binding.

This initial port adds support of ARC HS Development Kit board with some
basic features such serial port, USB, SD/MMC and Ethernet.

Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) and
heavily use IO Coherency for speeding-up DMA-aware peripherals.

Note as opposed to other ARC boards we link Linux kernel to
0x9000_0000 intentionally because cores 1 and 3 configured with DCCM
situated at our more usual link base 0x8000_0000. We still can use
memory region starting at 0x8000_0000 as we reallocate DCCM in our
platform code.

Note that PAE remapping for DMA clients does not work due to an RTL bug,
so CREG_PAE register must be programmed to all zeroes, otherwise it will
cause problems with DMA to/from peripherals even if PAE40 is not used.

This is board specific info so it should come from board config, such
as devicetree.

I've chosen to prefix these with "fcs," treating them as fusb302 driver
specific for now. We may want to revisit this and replace these with
properties which are part of a (to be written) generic type-c controller
devicetree binding.

Since this commit adds new dt-properties it also adds devicetree-bindings
documentation (which so far was absent for the fusb302 driver).
