  dt: add empty of_property_read_u32[_array] for non-dt
  dt: bindings: move SEC node under new crypto/
  dt: add helper function to read u32 arrays
  tty/serial: change of_serial to use new of_property_read_u32() api
  dt: add 'const' for of_property_read_string parameter **out_string
  dt: add helper functions to read u32 and string property values
  tty: of_serial: support for 32 bit accesses
  dt: document the of_serial bindings
  dt/platform: allow device name to be overridden
  drivers/amba: create devices from device tree
  dt: add of_platform_populate() for creating device from the device tree
  dt: Add default match table for bus ids

* ARM Primecell Peripherals
ARM, Ltd. Primecell peripherals have a standard id register that can be used to
identify the peripheral type, vendor, and revision. This value can be used for
driver matching.
Required properties:
- compatible : should be a specific value for peripheral and "arm,primecell"
Optional properties:
- arm,primecell-periphid : Value to override the h/w value with
Example:
serial@fff36000 {
compatible = "arm,pl011", "arm,primecell";
arm,primecell-periphid = <0x00341011>;
};

* UART (Universal Asynchronous Receiver/Transmitter)
Required properties:
- compatible : one of:
- "ns8250"
- "ns16450"
- "ns16550a"
- "ns16550"
- "ns16750"
- "ns16850"
- "nvidia,tegra20-uart"
- "ibm,qpace-nwp-serial"
- "serial" if the port type is unknown.
- reg : offset and length of the register set for the device.
- interrupts : should contain uart interrupt.
- clock-frequency : the input clock frequency for the UART.
Optional properties:
- current-speed : the current active speed of the UART.
- reg-offset : offset to apply to the mapbase from the start of the registers.
- reg-shift : quantity to shift the register offsets by.
- reg-io-width : the size (in bytes) of the IO accesses that should be
performed on the device. There are some systems that require 32-bit
accesses to the UART (e.g. TI davinci).
- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
RTAS and should not be registered.
Example:
uart@80230000 {
compatible = "ns8250";
reg = <0x80230000 0x100>;
clock-frequency = <3686400>;
interrupts = <10>;
reg-shift = <2>;
};
