[Why] During otg sync trigger, plane states are used to decide whether the otg is already synchronized or not. There are scenarions when otgs are disabled without plane state getting disabled and in such case the otg is excluded from synchronization. [How] Introduced pipe_idx_syncd in pipe_ctx that tracks each otgs master pipe. When a otg is disabled/enabled, pipe_idx_syncd is reset to itself. On sync trigger, pipe_idx_syncd is checked to decide whether a otg is already synchronized and the otg is further included or excluded from synchronization. v2: Don't drop is_blanked logic Reviewed-by: Jun Lei <Jun.Lei@amd.com> Reviewed-by: Mustapha Ghaddar <mustapha.ghaddar@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: meenakshikumar somasundaram <meenakshikumar.somasundaram@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Harry Wentland <harry.wentland@amd.com> Cc: torvalds@linux-foundation.org Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.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.
