Subject: [GIT PULL] : spi-mem/ecc changes for 5.18
Hi Mark,
Here are the changes that I've piled up in the MTD spi-mem-ecc branch. I
will merge this branch into mtd/next very soon but here is a PR for you
as well if needed.
Thanks, Miquèl
The following changes since commit e783362eb54cd99b2cac8b3a9aeac942e6f6ac07:
Linux 5.17-rc1 (2022-01-23 10:12:53 +0200)

spi: mxic: Add support for pipelined ECC operations (2022-02-10 09:32:30 +0100)
----------------------------------------------------------------
Topic branch bringing-in changes related to the support of ECC engines
that can be used by SPI controllers to manage SPI NANDs as well as
possibly by parallel NAND controllers. In particular, it brings support
for Macronix ECC engine that can be used with Macronix SPI controller.
The changes touch the NAND core, the NAND ECC core, the spi-mem layer, a
SPI controller driver and add a new NAND ECC driver, as well as a number
of binding updates.
Binding changes:
* Vendor prefixes: Clarify Macronix prefix
* SPI NAND: Convert spi-nand description file to yaml
* Raw NAND chip: Create a NAND chip description
* Raw NAND controller:
- Harmonize the property types
- Fix a comment in the examples
- Fix the reg property description
* Describe Macronix NAND ECC engine
* Macronix SPI controller:
- Document the nand-ecc-engine property
- Convert to yaml
- The interrupt property is not mandatory
NAND core changes:
* ECC:
- Add infrastructure to support hardware engines
- Add a new helper to retrieve the ECC context
- Provide a helper to retrieve a pilelined engine device
NAND-ECC changes:
* Macronix ECC engine:
- Add Macronix external ECC engine support
- Support SPI pipelined mode
SPI-NAND core changes:
* Delay a little bit the dirmap creation
* Create direct mapping descriptors for ECC operations
SPI-NAND driver changes:
* macronix: Use random program load
SPI changes:
* Macronix SPI controller:
- Fix the transmit path
- Create a helper to configure the controller before an operation
- Create a helper to ease the start of an operation
- Add support for direct mapping
- Add support for pipelined ECC operations
* spi-mem:
- Introduce a capability structure
- Check the controller extra capabilities
- cadence-quadspi/mxic: Provide capability structures
- Kill the spi_mem_dtr_supports_op() helper
- Add an ecc parameter to the spi_mem_op structure
