Commit c9be804c authored by Eric Anholt's avatar Eric Anholt

drm/vc4: Use common helpers for debugfs setup by the driver components.

The global list of all debugfs entries for the driver was painful: the
list couldn't see into the components' structs, so each component had
its own debugs show function to find the component, then find the
regset and dump it.  The components also had to be careful to check
that they were actually registered in vc4 before dereferencing
themselves, in case they weren't probed on a particular platform.
They routinely failed at that.

Instead, we can have the components add their debugfs callbacks to a
little list in vc4 to be registered at drm_dev_register() time, which
gets vc4_debugfs.c out of the business of knowing the whole list of
components.

Thanks to this change, dsi0 (if it existed) would register its node.

v2: Rebase on hvs_underrun addition.
v3: whitespace fixup
