[PATCH v2 0/2] drm/panel: Add support for Novatek NT36532 panel

[Junjie Cao <junjie.cao@linux.dev>]

This series adds support for panels using the Novatek NT36532 Display
Driver IC, a dual-DSI, dual-DSC controller that requires DPU support
for MIPI_DSI_MODE_DSC_ALL_SLICES_IN_PKT.

The first user is the CSOT PPC100HB1-1 panel found in the OnePlus Pad 2
(OnePlus Pad Pro in China) tablet: 3000x2120, dual-DSI in bonded mode,
DSC 1.2 with two slices per line.

This has been tested on the OnePlus Pad 2: the panel comes up in its
native 3000x2120 mode at 120Hz over dual-DSI in bonded mode with DSC,
and displays a stable image.

Changes in v2:
- Rebase onto next-20260727.
- Update to the new DRM APIs: devm_drm_panel_alloc(), devm_drm_panel_add().
- Drop the driver-private 'dsc_slice_per_pkt' plumbing and rely on
  MIPI_DSI_MODE_DSC_ALL_SLICES_IN_PKT instead.
- Send DCS commands through the second DSI link in dual-DSI mode.
- Change the refresh rate control register 0xb3 value from 0x41 to 0x40.
- Drop the of_node assignment when registering the secondary DSI device,
  matching panel-novatek-nt36523.
- Update author email to junjie.cao@linux.dev.
- Pick up Conor's Acked-by on the binding.
- Link to v1: https://lore.kernel.org/all/20251001135914.13754-1-caojunjie650@gmail.com
