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 drivers/spi/spi-rspi.c | 101 ++++++++++++++++++++++++++++------------- 1 file changed, 69 insertions(+), 32 deletions(-) -- 2.17.1 Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
