Pine64's Rock64 was missing the avdd supply properties on the hdmi node, causing the following warnings: dwhdmi-rockchip ff3c0000.hdmi: supply avdd-0v9 not found, using dummy regulator dwhdmi-rockchip ff3c0000.hdmi: supply avdd-1v8 not found, using dummy regulator In the Rock64 Schematic document version 2.0 those supplies are marked as DVIDEO_AVDD_1V0 and DVIDEO_AVDD_1V8 respectively, but in version 3.0 those are named HDMI_AVDD_1V0 and HDMI_AVDD_1V8, which is a bit clearer. In both versions those are connected to LDO3 and LDO1 respectively. While the DeviceTree property is named 'avdd-0v9-supply' the 'rockchip,dw-hdmi.yaml' binding document notes the following: A 0.9V supply that powers up the SoC internal circuitry. The actual pin name varies between the different SoCs and is usually HDMI_TX_AVDD_0V9 or sometimes HDMI_AVDD_1V0. So the 'vdd_10' reference is not an error.

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 reStructuredText 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.
