Subject: [PATCH 2/2] serial: unify serial bindings into a single dir
Move all bindings in bindings/tty/serial into bindings/serial so we only
have one place dir with serial/uart related bindings in it.
Signed-off-by: Kumar Gala <galak@...eaurora.org>

Note: I did not move msm_serial.txt with the feeling that Stephen will end up
removing it in his patch set.

- - "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
- or
- clocks phandle to refer to the clk used as per Documentation/devicetree
- /bindings/clock/clock-bindings.txt
-
-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.
-- no-loopback-test: set to indicate that the port does not implements loopback
- test mode
-- fifo-size: the fifo size of the UART.
-- auto-flow-control: one way to enable automatic flow control support. The
- driver is allowed to detect support for the capability even without this
- property.
