human-readable. To make it consistent with other devices, using property
name spi-tx-bus-width and spi-rx-bus-width instead of the previous one

Modify the probe routine to get the port line number
from device tree if the 'of_node' is populated in the
platform device. The driver can be built as module,
thus add an OF specific module device table as well
to support module auto loading.

This makes it possible to use the driver for AR9330
UART devices specified in device tree.

Let's fix up the msm serial device bindings so that it's clearer
what hardware is supported. Instead of using hsuart (for high
speed uart) let's use uartdm because that matches the actual name
of the hardware. Also, let's add the version information in case
we need to differentiate between different versions of the
hardware in the future. Finally, lets specify that clocks are
required (the clock bindings didn't exist when the original
binding was written) and also specify dma bindings just in case
we want to use it in software. We split the binding into two
files to make it clearer what's required and not required.

tree bindings. This patch reflects these changes in the bindings

v3…v4:
- remove the child node for USB. This is driver specific on won't be
  reflected in the device tree
- use the "mentor" prefix instead of "mg".
- use "dr_mode" istead of "mg,port-mode" for the port mode. The former
  is used by a few other drivers.

v2…v3:
- use proper usb-phy nodes in evm, bone and evmsk device tree.

v1…v2:
- use mg prefix for the Metor Graphics specific attributes
- use power in mA not in mA/2 as specifed in the USB2.0 specification
- use usbX-phy instead of usbX_phy
- use dma-controller instead of dma

The patch add basic support for the quad spi controller.

QSPI is a kind of spi module that allows single,
dual and quad read access to external spi devices. The module
has a memory mapped interface which provide direct interface
for accessing data form external spi devices.

The patch will configure controller clocks, device control
register and for defining low level transfer apis which
will be used by the spi framework to transfer data to
the slave spi device(flash in this case).

Test details:
-------------
Tested this on dra7 board.
Test1: Ran mtd_stesstest for 40000 iterations.
   - All iterations went through without failure.
Test2: Use mtd utilities:
  - flash_erase to erase the flash device
  - mtd_debug read to read data back.
  - mtd_debug write to write to the data flash.
 diff between the write and read data shows zero.

The original DMA support works only when RTS/CTS is enabled.
(see the "e8001632 serial: mxs-auart: add the DMA support for mx28")
But after several patches, DMA support has lost this limit.
(see the "bcc20f9e serial: mxs-auart: move to use generic DMA helper")

So an UART without the RTS/CTS lines may also enables the DMA support,
in which case the UART may gets unpredictable results.

This patch adds an optional property for the UART DT node
which indicates the UART has RTS and CTS lines, and it also means you
enable the DMA support for this UART.

This patch also adds a macro MXS_AUART_RTSCTS, and uses it to check
RTS/CTS before we enable the DMA for the UART.
