2024-03-11drm/panfrost: Replace fdinfo's profiling debugfs knob with sysfsAdrián Larumbe
Debugfs isn't always available in production builds that try to squeeze every single byte out of the kernel image, but we still need a way to toggle the timestamp and cycle counter registers so that jobs can be profiled for fdinfo's drm engine and cycle calculations. Drop the debugfs knob and replace it with a sysfs file that accomplishes the same functionality, and document its ABI in a separate file.
