fde8be2923 tty: of_serial: add no-loopback-test property
The loopback test mode is not implemented in all
NS16550 compatible UARTs. The 8250 driver uses the
UPF_SKIP_TEST flag to indicate this, however it is
not possible to set this flag via device-tree.

Add a new 'no-loopback-test' property, and modify
the of_serial driver to set the UPF_SKIP_TEST flag
if the property is present.

e4305f0c50 serial/of-serial: Add LPC3220 standard UART compatible string
This patch adds a "compatible" string for the new 8250 UART type PORT_LPC3220.
This is necessary for initializing LPC32xx UARTs via DT.

7423734e19 tty: of_serial: support for 32 bit accesses
Some platforms e.g. TI Davinci require 32-bit accesses to the UARTs.
The of_serial driver currently registers all UARTs as UPIO_MEM.  Add a
new attribute "reg-io-width" to allow the port to be registered with
different IO width requirements.

61ab1a90d8 dt: document the of_serial bindings
The of_serial bindings can be used to register a number of serial
devices.  Document this binding with all of the others.

v3: remove device-type and clarify used-by-rtas
