[PATCH v2 0/5] serial: Add Generic Serial Device Tree Bindings

[Geert Uytterhoeven <geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>]

	Hi Greg, Jiri,

This patch series, against next-20160422, introduces Generic Serial
Device Tree Bindings, and converts drivers using vendor-specific DT
properties to the generic properies where appropriate.

The Generic Serial Device Tree Bindings document a set of generic
properties for describing UARTs in a device tree:
  1. The GPIO modem control properties are currently duplicated across
     hardware-specific binding documentation,
  2. The property for dedicated RTS/CTS hardware flow control lines is
     already supported by several drivers, albeit with a vendor-specific
     prefix, hence make it generic.
Whether these generic properties apply to a particular device still
depends on the DT bindings of the actual device.

The old (deprecated) vendor-specific properties are still supported by
the drivers for backwards compatibility.

Changes compared to v1:
  - Add Acked-by,
  - Drop out[12]-gpios from the bindings (a patch to drop it from the
    code has been submitted separately).

I will sent out patches to update the actual DTS files later, after this
series has been integrated into mainline.  DTS updates typically go
through a different path (e.g. arm-soc), and RTS/CTS support would be
broken if the DTSes would be updated before the drivers.

Thanks for applying!
