Maxime Ripard 8375d3ac8e dmaengine: bcm2835: HACK: Support DMA-Lite channels
The BCM2712 has a DMA-Lite controller that is basically a BCM2835-style
DMA controller that supports 40 bits DMA addresses.

We need it for HDMI audio to work, but this breaks BCM2835-38 so we
should rework this later.

dmaengine: bcm2835: Fix dma driver for BCM2835-38

The previous commit broke support on older devices.
Make the breaking parts of patch conditional on
the device being used.

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.
