Hi all,This series of patches fixes and extend the support of QSPI memories in the SPI flash framework. The updates are split into many parts to make it easier to understand and review but they should be considered as a whole. This was tested on a Atmel sama5d2 xplained board with a Micron n25q128a memory. Best regards, Cyrille Cyrille Pitchen (18): Revert "sf: Fix quad bit set for micron devices" sf: call spi_claim_bus() and spi_release_bus() only once per read, write or erase sf: replace spi_flash_read_common() calls by spi_flash_cmd_read() sf: remove spi_flash_write_common() sf: export spi_flash_wait_ready() function sf: share erase generic algorithm sf: share write generic algorithm sf: share read generic algorithm sf: add hooks to handle register read and write operations sf: move support of SST flash into generic spi_flash_write_alg() sf: fix selection of supported READ commands for QSPI memories sf: fix detection of QSPI memories when they boot in Quad or Dual mode sf: add helper function to set the number of dummy bytes sf: add 4byte address opcodes sf: prepare next fixes to support of QSPI memories by manufacturer sf: fix support of Micron memories ARM: at91: clock: add function to get QSPI clocks sf: add driver for Atmel QSPI controller
Appreciate for the work, we're working on spi-nor framework[1] planning to push in couple of weeks. Will let you know once it merged so that you can add your changes on top of that.
