commit dc900431337f5f861e3cc47ec5be5a69db40ee34 upstream.
Due to what looks like a copy-paste error, the ECSPI2_MISO pad is not
muxed for SPI mode and causes reads from a slave-device connected to the
SPI header to always return zero.
Configure the ECSPI2_MISO pad for SPI mode on the gw71xx, gw72xx and
gw73xx families of boards that got this wrong.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
