Hi all,
This patch series contains various improvements for the AT25 SPI EEPROM
driver, related to SPI transfers.
Tested on a Renesas Ebisu development board with R-Car E3 using MSIOF
and a 25LC040 EEPROM. The MSIOF SPI Controller can only do DMA for
transfers with a length that is a multiple of 4 bytes.
Thanks!
Geert Uytterhoeven (3):
eeprom: at25: Drop obsolete cast in at25_ee_write()
eeprom: at25: Use spi_message_init_with_transfers() instead of open
coding
eeprom: at25: Split writes in two SPI transfers to optimize DMA
