Note from Vignesh(mtd subsystem maintainer): This series is a subset of "[PATCH v12 0/4] spi: cadence-quadspi: Add support for the Cadence QSPI controller" by Ramuthevar,Vadivel MuruganX that intended to move cadence-quadspi driver to spi-mem framework Those patches were trying to accomplish too many things in a single set of patches and need to split into smaller patches. This is reduced version of above series. Changes that are intended to make migration easy are split into separate patches. Patches 1 to 3 drop features that cannot be supported under spi-mem at the moment (backward compatibility is maintained). Patch 4-5 are trivial cleanups. Patch 6 does the actual conversion to spi-mem and patch 7 moves the driver to drivers/spi folder. I have tested both INDAC mode (used by non TI platforms like Altera SoCFPGA) and DAC mode (used by TI platforms) on TI EVMs. Patches to move move bindings over to "Documentation/devicetree/bindings/spi/" directory and also conversion of bindig doc to YAML will be posted separately. Support for Intel platform would follow that.
