This series is a subset of "[PATCH v12 0/4] spi: cadence-quadspi: Add
support for the Cadence QSPI controller" by Ramuthevar,Vadivel MuruganX
<[email protected]> 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.
Changes since v12
- Drop intel platform related changes
- Drop DT bindings movement to YAML
- Split patch moving driver to spi-mem framework framework into
multiple patches as suggested by Tudor.
v12: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=163343&state=%2A&archive=both
Vadivel,
I have maintained the additional changes needed on top of this series
for Intel platform that were part of your v12 series here (needs cleanup):
https://github.com/r-vignesh/linux.git branch: cqspi-mig
Please use above branch to test the same.

mtd: spi-nor: Convert cadence-quadspi to use spi-mem framework
spi: Move cadence-quadspi driver to drivers/spi/
Vignesh Raghavendra (4):
mtd: spi-nor: cadence-quadspi: Drop cdns,is-decoded-cs property
mtd: spi-nor: cadence-quadspi: Provide a way to disable DAC mode
