Subject: [PATCH -next 00/12] OF earlycon cleanup

Hi Greg, Grant & Rob,

This patch series builds on my earlier "Extensible console matching &
direct earlycon" to add several useful features to earlycon:
* Proper port i/o configuration from DT node with of_serial properties
  (such as reg-io-width, reg-shift and reg-offset)
* Proper console name & index initialization from earlycon name
  (for both command line and DT-defined earlycons)
* Support for DT 'stdout-path' options pass-through to earlycon setup
* Improved log messages for troubleshooting
* Support for multiple OF earlycon declarations so different
  compatible strings can specify the same OF earlycon

Lastly, this patch series adds an omap8250 OF earlycon. I don't think
the last patch requires the "Split 8250 driver" to work but it won't
apply cleanly without it.

Requires: "libfdt: Teach fdt_path_offset() about ':' path separator"

Regards
