serial: sh-sci: Drop the sci_fck clock fallback (2015-12-17 11:19:12 +0100)
Summary:
- Clean up the naming of clocks in the sh-sci driver and its DT bindings,
- Add support for the optional external clock on (H)SCI(F), where this pin
can serve as a clock input,
- Add support for the optional clock sources for the Baud Rate
Generator for External Clock (BRG), as found on some SCIF variants
and on HSCIF.
Thanks for pulling!
