On i.MX8MQ EVK board, VDD_ARM is from a DC-DC converter which is always ON, the GPIO1_IO13 is ONLY to switch VDD_ARM's voltage between 0.9V and 1V for CPU DVFS, so VDD_ARM's GPIO regulator should be always ON to avoid below confusion after kernel boot up: imx8mqevk login: [ 31.776619] vdd_arm: disabling Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
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.
