994ea402c7 drm/panel: Rename Sony ACX424 to Novatek NT35560 
A code drop from Sony Mobile reveals that the ACX424 panels are
built around the Novatek NT35560 panel controllers so just bite
the bullet and rename the driver and all basic symbols so that
we can modify this driver to cover any other panels also using
the Novatek NT35560 display controller.

6ed19359d6 drm/panel-edp: Allow querying the detected panel via debugfs 
Recently we added generic "edp-panel"s probed by EDID. To support
panels in this way we look at the panel ID in the EDID and look up the
panel in a table that has power sequence timings. If we find a panel
that's not in the table we will still attempt to use it but we'll use
conservative timings. While it's likely that these conservative
timings will work for most nearly all panels, the performance of
turning the panel off and on suffers.

We'd like to be able to reliably detect the case that we're using the
hardcoded timings without relying on parsing dmesg. This allows us to
implement tests that ensure that no devices get shipped that are
relying on the conservative timings.

Let's add a new debugfs entry to panel devices. It will have one of:
* UNKNOWN - We tried to detect a panel but it wasn't in our table.
* HARDCODED - We're not using generic "edp-panel" probed by EDID.
* A panel name - This is the name of the panel from our table.

In the function panel_simple_probe() the pointer panel->desc is
assigned to the passed pointer desc. If function panel_dpi_probe()
is called panel->desc will be updated, but further on only desc
will be evaluated. So update the desc pointer to be able to use
the data from the function panel_dpi_probe().

9bf7123bb0 drm/panel: Delete panel on mipi_dsi_attach() failure 
Many DSI panel drivers fail to clean up their panel references on
mipi_dsi_attach() failure, so we're leaving a dangling drm_panel
reference to freed memory. Clean that up on failure.

Noticed by inspection, after seeing similar problems on other drivers.
Therefore, I'm not marking Fixes/stable.
