commitf6498b922eupstream. Pandora_wl1251_init_card was used to do special pdata based setup of the sdio mmc interface. This does no longer work with v4.7 and later. A fix requires a device tree based mmc3 setup. Therefore we move the special setup to omap_hsmmc.c instead of calling some pdata supplied init_card function. The new code checks for a DT child node compatible to wl1251 so it will not affect other MMC3 use cases. Generally, this code was and still is a hack and should be moved to mmc core to e.g. read such properties from optional DT child nodes.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
