The Motorola Signature uses a 1264x2780 BOE AMOLED panel driven by an
Ilitek ILI97680A. It is a MIPI DSI command mode panel with DSC 1.2
compression on four lanes. This series adds the devicetree binding and a
driver for it.

Two things are specific to this panel. The DSC picture parameter set is
written to a vendor register on command page 7 instead of being sent as a
standard PPS packet, and the brightness range is 0 to 16180 over DCS.

Tested on a Motorola Signature with the msm DRM driver: the panel lights
up at its native resolution and Phosh renders on it.

I used an LLM (Claude) to help write these patches and their commit
messages. I reviewed all of them and tested the result on the device.

[Severity: Medium]
Should compatible require a specific panel compatible string (such as
boe,<panel-model> or motorola,signature-panel) followed by ilitek,ili97680a
as a fallback?

ILI97680A is the display controller IC driving a specific 1264x2780 BOE
AMOLED panel.  Other panels built around the same controller can have
different resolutions, dimensions, DSC settings, and initialization
sequences, so using the bare controller compatible alone prevents
distinguishing them in future Devicetrees without breaking ABI compatibility.

From: Venkat Yadlapati <venkat.yadlapati@yahoo.com>

Add a driver for the 1264x2780 BOE AMOLED panel driven by an Ilitek
ILI97680A, found in the Motorola Signature. The panel runs in DSI
command mode on four lanes with DSC 1.2 at 10 bits per component and
8 bits per pixel, two 632x20 slices per line.

The picture parameter set is not taken from the standard DSC PPS packet
but written to a vendor register on command page 7. Brightness is
controlled through DCS with a range of 0 to 16180.
