If hdmi uboot logo is disabled and hdmi resolution is HDMI 2.0 resolution(such as 4k60), hdmi->logo_plug_out will be set to true and won't be clear before hdmi is enabled. After hdmi is enabled, hdmi->disabled is set to false, and then mode_changed is set to true. hdmi will be disabled and enabled again. hdmi->logo_plug_out is mainly used to determine whether hdmi has been plugged from the end of uboot to the completion of kernel driver initialization when the uboot logo is enabled. So when setting it to true, it is necessary to determine whether the uboot logo is enabled. Change-Id: I1256f7d5e531dcb3e3ed8209a7839019aadef32e Signed-off-by: Algea Cao <algea.cao@rock-chips.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.
