First patch moves driver over to spi-mem framework and implement spi_mem_ops. This is require to support more SPI Flash opcodes like SFDP parsing etc. Series is in prepartion to add Octal mode for support for the same driver to support OSPI version of the controller.
Second patch adds DAC mode that provide memory mapped access to flash. This greatly increases the read throughput. Tested with mt25qu512 flash and s25fl512 flash Simon, Would greatly appreciate if you could test this series on platforms that you have access to?
