Peter Ujfalusi 808d885740 ASoC: ti: davinci-mcasp: Handle missing required DT properties
[ Upstream commit 1b4fb70e5b28a477478417a7958e0228460ffe68 ]

McASP needs three required properties to be usable for audio:
op-mode, tdm-slots and the serial-dir array.

Instead of probing the driver even without the needed information we should
make sure that all the parameters are provided for operation.

The fact that McASP can act as a GPIO controller for it's pins complicates
this a bit, but as a general rule we can:
- we fail the probe if McASP is not configured to be used as gpiochip
- we will not register the DAI (and PCM) if gpiochip is defined

README

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.
