Hello,

This patch set adds device tree bindings for the sh sci serial port
devices and adds OF parsing to the sh-sci driver.

The bindings are based on Bastian Hecht's proposal (see
http://www.spinics.net/lists/arm-kernel/msg228129.html). The approach
taken here is more minimalistic: instead of describing all hardware
characteristics that vary between the SCI device revisions in DT (such as
registers layout), that information is stored in the driver and selected
based on the compatible property value. Only SCI revisions used on ARM
devices are supported through DT, as DT support for SuperH is nowhere
down the line.

The first three patches clean up the sh-sci driver. They're not strictly
required for OF support but make sense nonetheless. The last two patches
add OF parsing to the sh-sci driver and create DT bindings documentation.

The patches have been test on a Lager board (r8a7790-based). Support for
other SoCs will be added as needed. Note that all current Renesas ARM
SoCs seem to be compatible with the generic (H)SCI(F)(AB) devices, but
the plan is for their DT bindings to list the SoC-specific version in
case incompatibilities are found later.

  serial: sh-sci: Sort headers alphabetically
  serial: sh-sci: Remove baud rate calculation algorithm 5
  serial: sh-sci: Simplify baud rate calculation algorithms
  serial: sh-sci: Add device tree bindings documentation

Laurent, is this series waiting on anything other than a review of the
bindings from the Device-Tree people?
It's only waiting for review of the DT bindings and their implementation 
(patches 4/5 and 5/5). As I've modified Bastian's patch in 4/5 I'd like to 
give him an opportunity to review it as well.
