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!
