There is HPD unplug interrupts missed at scenario of an irq_hpd followed by unplug interrupts with around 10 ms in between. Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts, irq_hpd handler should not issues either aux or sw reset to avoid following unplug interrupt be cleared accidentally. This patch also postpone handling of irq_hpd until connected state if it happened at connection pending state. Changes in V2: -- add postpone handling of irq_hpd until connected state -- check DP_TRAINING_1 instead of DP_TRAINING_NONE Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.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.
