[PATCH v3 0/7] Renesas *SCIF* RX FIFO support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi!

This series implements support for using RX FIFO thresholds higher than one
in PIO mode on SCIF, HSCIF, SCIFA and SCIFB serial ports.

This revision has been rebased onto renesas-drivers-2017-01-24-v4.10-rc5 and
adds the missing changelog for "serial: sh-sci: increase RX FIFO trigger
defaults for (H)SCIF" requested by Geert and Greg.
