Subject: [PATCH] RFC: Example schema files written in Python
Date:   Mon, 29 Apr 2019 16:41:43 -0600
Message-Id: <20190429224143.192506-1-sjg@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Most of these are hand-written, but xilinx-xadc.py is auto-generated by
binding_to_py.py as an example of the use of that tool.

This is part of a proof-of-concept device-tree validator. See the patch
on the dtc mailing list for details:

   RFC: Python-based device-tree validation
