Subject: [PATCH 0/8] spi: rspi: Bit rate improvements
Date: Mon,  8 Jun 2020 11:59:32 +0200	[thread overview]
Message-ID: <20200608095940.30516-1-geert+renesas@glider.be> (raw)

	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

when I'm talking to journalists I just say "programmer" or something like that.
