The Banana Pi M2 Ultra is an SBC based on the Allwinner R40 SoC. The
form factor and position of various connectors, leds and buttons is
similar to the Banana Pi M1+, Banana Pi M3, and is exactly the same
as the latest Banana Pi M64.

It features:

  - X-Powers AXP221s PMIC connected to i2c0
  - 2 GB DDR3 DRAM
  - 8 GB eMMC
  - micro SD card slot
  - DC power jack
  - HDMI output
  - MIPI DSI connector
  - 2x USB 2.0 hosts
  - 1x USB 2.0 OTG
  - gigabit ethernet with Realtek RTL8211E transceiver
  - WiFi/Bluetooth with AP6212 chip, with external antenna connector
  - SATA and power connectors for native SATA support
  - camera sensor connector
  - consumer IR receiver
  - audio out headphone jack
  - onboard microphone
  - red, green, and blue LEDs
  - debug UART pins
  - Li-Po battery connector
  - Raspberry Pi B+ compatible GPIO header
  - power, reset, and boot control buttons

This patch adds a dts file that enables UART, MMC and PMIC support.

The Allwinner R40 SoC is marketed as the successor to the A20 SoC.
The R40 is a smaller chip than the A20, but features the same set
of programmable pins, with a couple extra pins and some new pin
functions. The chip features 4 Cortex-A7 cores and a Mali-400 MP2
GPU. It retains most if not all features from the A20, while adding
some new features, such as MIPI DSI output, or updating various
hardware blocks, such as DE 2.0.

The TCONs on A31/A31s can select either backend as its input. As there
is no configurable mux in the backend or DRC to redirect their output,
or for the DRC to select an input, the connections are presumably from
the each DRC to each TCON, with the TCON having two input ports, like
the following diagram:

	Backend 0  -------  DRC 0  ------- [0]  TCON 0
				   --   -- [1]
                                     \ /
				      X
				     / \
				   --   -- [0]
	Backend 1  -------  DRC 1  ------- [1]  TCON 1

The kernel watchdog is a great debugging tool for finding tasks that
consume a disproportionate amount of CPU time in contiguous chunks. One
can imagine building a similar watchdog for arbitrary driver threads
using save_stack_trace_tsk() and print_stack_trace(). However, this is
not viable for dynamically loaded driver modules on ARM platforms
because save_stack_trace_tsk() is not exported for those architectures.
Export save_stack_trace_tsk() for the ARM architecture to align with
x86 and support various debugging use cases such as arbitrary driver
thread watchdog timers.

The ARM-ARM has two bits in the ESR/HSR relevant to external aborts.
A range of {I,D}FSC values (of which bit 5 is always set) and bit 9 'EA'
which provides:
> an IMPLEMENTATION DEFINED classification of External Aborts.

This bit is in addition to the {I,D}FSC range, and has an implementation
defined meaning. KVM should always ignore this bit when handling external
aborts from a guest.

Remove the ESR_ELx_EA definition and rewrite its helper
kvm_vcpu_dabt_isextabt() to check the {I,D}FSC range. This merges
kvm_vcpu_dabt_isextabt() and the recently added is_abort_sea() helper.

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. Each of them could modify the
rate of the main audio pll parent.

The main audio pll clock can output 620MHz to 700MHz.
