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 [email protected]. - Pick up Conor's Acked-by on the binding. - Link to v1: https://lore.kernel.org/all/[email protected] Junjie Cao (2): dt-bindings: display: panel: Add Novatek NT36532 drm/panel: Add Novatek NT36532 panel driver .../display/panel/novatek,nt36532.yaml | 83 ++++ MAINTAINERS | 7 + drivers/gpu/drm/panel/Kconfig | 10 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-novatek-nt36532.c | 430 ++++++++++++++++++ 5 files changed, 531 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/novatek,nt36532.yaml create mode 100644 drivers/gpu/drm/panel/panel-novatek-nt36532.c base-commit: 0d33d21e47d9dc66f91e44da3fc9220c74d93df7 -- 2.43.0
