On the XO-1.75, this node represents a bus interface that operates in slave
mode and thus is only able to accommodate a single subnode; no address
cells are necessary.
The Documentation/devicetree/bindings/spi/spi-controller.yaml binding
prefers that we drop the property instead of setting it to zero.
This fixes a DT validation error:
arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000:
{ ... } is valid under each of {'required': ['spi-slave']},
{'required': ['#address-cells']}
We also need to drop #size-cells:
arch/arm/boot/dts/mmp2-olpc-xo-1-75.dt.yaml: spi@d4037000:
'#address-cells' is a dependency of '#size-cells'

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.
