Instead of keeping the IPU clock enabled constantly, enable and disable it on demand, when the IPU plane is used. That way, we won't use any extra power when the IPU is not used. v2: Explain the reason of this patch Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Paul Cercueil <paul@crapouillou.net> Link: https://patchwork.freedesktop.org/patch/msgid/20200730144830.10479-4-paul@crapouillou.net
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.
