[PATCH 0/3] Add support for Fujitsu MB85RS128TY

[Jonas Rebmann]

The Fujitsu MB85RS128TY FRAM chips behave almost identically to the
Microchip 48L640. This series adds their support to the mchp48l640
driver.

[PATCH 1/3] mtd: mchp48l640: make WEL behaviour configurable

[Jonas Rebmann]

From: David Jander <david@protonic.nl>

The 48L640 resets the WEL bit (the Write Enable Latch bit in the status
register) to zero on the completion of write operations. In preparation
to support chips behaving differently, introduce .auto_disable_wel
capability, and, if it's missing, explicitly reset the WEL bit after
writes.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH 3/3] mtd: mchp48l640: add support for Fujitsu MB85RS128TY FRAM

[Jonas Rebmann]

From: David Jander <david@protonic.nl>

The Fujitsu FRAM chips use the same command set as Microchip EERAM.
The only differences are that the Fujitsu FRAM chips don't really have a
page size limit, nor do they automatically reset the WEL bit.

[PATCH 3/3] mtd: mchp48l640: add support for Fujitsu MB85RS128TY FRAM

[Jonas Rebmann]

From: David Jander <david@protonic.nl>

The Fujitsu FRAM chips use the same command set as Microchip EERAM.
The only differences are that the Fujitsu FRAM chips don't really have a
page size limit, nor do they automatically reset the WEL bit.
