2023-01-26Documentation: accel: escape wildcard in special file pathBagas Sanjaya
Stephen Rothwell reported htmldocs warning then merging accel tree: Documentation/accel/introduction.rst:72: WARNING: Inline emphasis start-string without end-string. Sphinx confuses the file wildcards with inline emphasis (italics), hence the warning. Fix the warning by escaping wildcards.

2023-01-26docs: accel: Fix debugfs pathJeffrey Hugo
The device specific directory in debugfs does not have "accel". For example, the documentation says device 0 should have a debugfs entry as /sys/kernel/debug/accel/accel0/ but in reality the entry is /sys/kernel/debug/accel/0/ Fix the documentation to match the implementation.

2022-11-22doc: add documentation for accel subsystemOded Gabbay
Add an introduction section for the accel subsystem. Most of the relevant data is in the DRM documentation, so the introduction only presents the why of the new subsystem, how are the compute accelerators exposed to user-space and what changes need to be done in a standard DRM driver to register it to the new accel subsystem.
