[PATCH v2 0/6] panel: visionox-rm69299: modernize & support the variant found in the SHIFT6mq

[Neil Armstrong]

Modernize the driver with panel_desc, _multi, const supplies and new panel
init with refcounting.

Re-spin of [1] and [2] to finally document and support this panel
variant.

Changes in v2:
- Add panel_desc to support the variant
- Switch to _multi calls
- Switch to const supplies
- Switch to new panel alloc
- Fix shift panel init seq name
- Link to v1: https://lore.kernel.org/r/20250507-topic-misc-shift6-panel-v1-0-64e8e98ff285@linaro.org
