[PATCH 0/8] spi: rspi: Bit rate improvements

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

	Hi Mark,

This patch series contains several improvements for the Renesas SPI/QSPI
driver related to bit rate configuration.

This has been tested on RSK+RZA1 (RSPI) and R-Car M2-W/Koelsch (QSPI),
using a scope and logic analyzer, except for the by-one divider on QSPI.
This has not been tested on legacy SuperH, due to lack of hardware.

Thanks for your comments!

Geert Uytterhoeven (8):
  spi: rspi: Remove useless .set_config_register() check
  spi: rspi: Use requested instead of maximum bit rate
  spi: rspi: Clean up Bit Rate Division Setting handling
  spi: rspi: Increase bit rate accuracy on RZ/A
  spi: rspi: Increase bit rate range for RSPI on SH
  spi: rspi: Increase bit rate range for QSPI
  spi: rspi: Fill in spi_transfer.effective_speed_hz
  spi: rspi: Fill in controller speed limits

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
