All RPi 1 and 2 boards used the PWM (audio out) on pin 40 and 45. So it was easy to define them in bcm2835-rpi.dtsi. Starting with RPi 3 this wont work anymore, because it uses pin 40 and 41. Furthermore the Zero variants doesn't have audio out. This patch fixes this pin conflict by moving the PWM node to the board-level. Change summary: RPi 3 B: PWM1 45 -> 41 Zero, Zero W: PWM disabled all other: no functional change Reported-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Reviewed-by: Eric Anholt <eric@anholt.net> Signed-off-by: Eric Anholt <eric@anholt.net> |

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
