From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx> Patches from 1 to 11 are minor fixes or cosmetics. Patches 12 and 13 introduce the sam9x60 qspi controller. sam9x60 qspi controller tested with sst26vf064b jedec,spi-nor flash. Backward compatibility test done on sama5d2 qspi controller and mx25l25635e jedec,spi-nor flash. v6: patch 13/13: add a caps instance to the sama5d2 entry instead of allowing caps to be NULL v5: - use WICR for sam9x60 - remove ops hooks and introduce caps->has_ricr - get rid of the cfg struct - group IO accesses together in atmel_qspi_set_cfg() v4: - s/smm/mr, init controller in serial memory mode by default - drop local variables that kept aq->regs and &pdev->dev, the compiler should be smart enough to store them in a register - introduce QSPI_IFR_TFRTYP_MEM - add comment saying QSPI_IFR_APBTFRTYP_READ is defined in sam9x60 - s/sama5d2_qspi_modes/atmel_qspi_modes, modes are the same both controllers - fix kernel doc header - move comment in function body - collect R-b tags v3: - update smm value when different. - treat just regular spi transfers when introducing sam9x60 qspi IP. Mem transfers will be added together with dirmap support. - reorganize the code and change ops functions pointers to avoid code duplication. - rename aq->clk to aq->pclk to indicate that it's a peripheral clock. - drop unused and NOP transfer macros. - add Suggested-by tags, reword some commits. v2: - cache MR value, - drop iomem wrappers, - make "pclk" clock-name mandatory even for sama5d2, - rework clock handling, - reorder setting of register values in set_cfg() calls, - collect R-b tags.
