Add snapshot points across dpu driver to trigger dumps when critical
errors are hit.
changes in v5:
- change the callers to use the snapshot function directly

Add an API to take a snapshot of DSI controller registers. This API
will be used by the msm_disp_snapshot module to capture the DSI
snapshot.

Add the msm_disp_snapshot module which adds supports to dump dpu
registers and capture the drm atomic state which can be used in
case of error conditions.
changes in v5:
- start storing disp_state in msm_kms instead of dpu_kms
- get rid of MSM_DISP_SNAPSHOT_IN_* enum by simplifying the functions
This series adds support to use devcoredump for DPU driver. It introduces
the msm_disp_snapshot module which assists in the capturing of register dumps
during
error scenarios. When a display related error happens, the msm_disp_snapshot
module
captures all the relevant register dumps along with th
Add support to take the register snapshot of dsi, dp and dpu

Currently drm_atomic_print_state() internally allocates and uses a
drm_info printer. Allow it to accept any drm_printer type so that
the API can be leveraged even for taking drm snapshot.
Rename the drm_atomic_print_state() to drm_atomic_print_new_state()
so that it reflects its functionality bett
Some dongle may generate more than one irq_hpd events in a short period of
time. This patch will treat those irq_hpd events as single one and service
only one irq_hpd event.

Maybe when the cable is disconnected the DP phy should be shutdown and
some bit in the phy could effectively "cut off" the aux channel and then
NAKs would start coming through here in the DP controller I/O register
space. This patch have DP aux channel read/write to return NAK immediately

This set is part of a larger effort attempting to clean-up W=1

niggly little warnings.
