The driver contains a low-level hardware driver for the TAS5713 and the drivers for the Raspberry Pi I2S subsystem. TAS5713: return error if initialisation fails Existing TAS5713 driver logs errors during initialisation, but does not return an error code. Therefore even if initialisation fails, the driver will still be loaded, but won't work. This patch fixes this. I2C communication error will now reported correctly by a non-zero return code. HiFiBerry Amp: fix device-tree problems Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.
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.
