e6f6d63ed1 drm/msm: add headless gpu device for imx5
This patch allows using drm/msm without qcom display hardware. It adds a
amd,imageon compatible, which is used instead of qcom,adreno, but does
not require a top level msm node.

c0fec7f562 drm/msm/gpu: Capture the GPU state on a GPU hang
Capture the GPU state on a GPU hang and store it for later playback
via the devcoredump facility. Only one crash state is stored at a
time on the assumption that the first hang is usually the most
interesting. The existing crash state can be cleared after capturing
it and then a new one will be captured on the next hang.

4f776f4511 drm/msm/gpu: Convert the GPU show function to use the GPU state
Convert the existing GPU show function to use the GPU state to
dump the information rather than reading it directly from the hardware.
This will require an additional step to capture the state before
dumping it for the existing nodes but it will greatly facilitate reusing
the same code for dumping a previously captured state from a GPU hang.

81895b5409 drm/msm: Remove drm_debugfs_remove_files() calls
drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so it's not necessary to call
drm_debugfs_remove_files(). Additionally it uses
debugfs_remove_recursive() to clean up the debugfs files, so no need
to do that.

b5c3714fe8 drm/mm: Convert to drm_printer
Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.

v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/msm_debugfs.c:141:5: warning: no previous prototype for 'msm_debugfs_init' [-Wmissing-prototypes]
drivers/gpu/drm/msm/msm_debugfs.c:158:6: warning: no previous prototype for 'msm_debugfs_cleanup' [-Wmissing-prototypes]

In fact, these functions are declared in
drivers/gpu/drm/msm/msm_debugfs.h.
So this patch adds missing header dependencies.
