Subject: [PATCH v2 0/7] spi: rspi: Bit rate improvements
Date: Wed, 19 Aug 2020 14:58:57 +0200 [thread overview]
Message-ID: <20200819125904.20938-1-geert+renesas@glider.be> (raw)
Hi Mark,
This patch series contains several improvements for the Renesas SPI/QSPI
driver related to bit rate configuration.
Changes compared to v1
(https://lore.kernel.org/r/20200608095940.30516-1-geert+renesas@glider.be):
- Drop accepted patch.
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 (7):
spi: rspi: Remove useless .set_config_register() check
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
