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. Signed-off-by: Maxime Ripard <maxime@cerno.tech> 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. Fixes: 6e1856ac7c39 ("dmaengine: bcm2835: HACK: Support DMA-Lite channels") Signed-off-by: Dom Cobley <popcornmix@gmail.com>
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.
