Write to hardware registers should be exposed for only debug
purpose. Hence use CONFIG_DYNAMIC_DEBUG to restrict register
writes only for debug defconfig.

Disable double buffer vsync configuration while
enabling clk and cmd state switch sequence. Leaving
this configuration in enable state may cause different
issues for different state switch. Clock state switch
may see a vsync delay for solver disable. Command
state switch may not update the vsync source.

Force a disconnect if the simulation client disables simulation
before disconnecting from the simulated sink. This ensures that
the driver will not erroneously attempt AUX transactions in
subsequent interactions after simulation is disabled.

Report the HDR10+ sink capability and payload data when user-space
reads the "hdr" debugfs node. Also add support for reporting HDR
properties for MST sessions via the new "hdr_mst" debugfs node.
Write support for this node was removed since it updated the
connector state in an inconsistent way, therefore HDR updates must
come from the atomic commit.

Existing cwb implementation waits for WB done interrupt in
wait_for_commit_done API call. This serializes the cwb commit
and causes frame trigger delay on primary display. MDSS hw allows
to trigger the cwb frame when previous frame is in-progress. This
change updates driver to allow parallel frame trigger for cwb
enabled display. It releases frame N cwb output buffer in frame
N+1 wait_for_commit done call.

The open method for the debug fops are supposed to extract
the appropriate register base for the corresponding
hardware blocks, which are later used for the register
read and writes for the associated hardware block. But
the current open method being used points to some random
register base which can lead to fatal issues when performed
reads and writes to registers. Hence implemented a new
open method to extract the appropriate register base of the
various mdp hardware blocks. This patch also fixes
the valid sub range check against the corresponding
hardware blocks instead of checking across all the hardware
blocks.

Userspace is not supposed to request vblank until crtc is enabled,
because drm framework rejects the request if crtc is not enabled.
Any vblank request prior to that need to be cached in the userspace.
Hence removing the cache logic from the downstream driver.

The display driver uses ktime_to_us to timestamp the messages
in the sde event log. But the kernel logs use local_clock to
timestamp the messages. Using same timestamp routine in sde event
log helps to correlate the messages from both the logs
for debug purpose.

Current sde driver allows vblank enable and wait requests
even after crtc is disabled which would eventually lead to
enable of irq and timeouts in caller context. This change fixes
it by updating vblank callback status as 'on' during crtc enable
and shutdowns vblank callbacks before crtc disable is complete.
