Hi Everyone,

Thanks to Rob Herring for Acking the device tree bindings part of the patch. Does anyone have any feedback for the rest of the patch set?

Thanks,

Matthew Gerlach

This patch set adds a spi-nor flash driver for the Altera ASMI Parallel II
IP Core. This driver was created based on feedback from Marek Vasut,
Cyrill Pitchen, and Michal Suchanek regarding Version 2 of the Altera
Quadspi Controller: https://lkml.org/lkml/2017/6/26/518

The overall problem with Version 2 of the Altera Quadspi Controller and
its driver was the fact that there was much duplication of code and logic
with the spi-nor framework. This new combination of fpga hardware and
software "gets out of the way" of the spi-nor framework. The result is a
much simpler driver with the spi-nor framework performing the bulk of the work.

Patch 1 contains the device tree bindings for the driver for
the Altera ASMI-Parallel II IP Core.

Patch 2 contains the driver code for the Altera ASMI-Parallel II IP Core.
This driver supports being configured via a device tree or with platform
data. In the later case, the memory for the registers has been remapped.

Patch 3 contains a work around for some non-standard behavior of EPCQ flash.
