Subject: [PATCH v2 0/3] Altera ASMI Parallel II IP Core
Date: Wed, 20 Sep 2017 11:28:56 -0700 [thread overview]
Message-ID: <1505932139-2905-1-git-send-email-matthew.gerlach@linux.intel.com> (raw)
From: Matthew Gerlach <matthew.gerlach@linux.intel.com>
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.
