[PATCH 0/3] drm/panel: Add Anapass ANA38407 DDIC

From: Nizat Mikayilli via B4 Relay

Date: Sat Nov 07 2026 - 14:48:06 EST


This series adds a driver for the Samsung AMSA10FA01, the 2560x1600
AMOLED panel of the Samsung Galaxy Tab S9 Wi-Fi (SM8550). It is a
command mode DSI panel with DSC, driven by an Anapass ANA38407 DDIC.
The binding and driver are named after the DDIC.

Only the 120 Hz mode of panel revision D is supported. The init
sequence comes from the vendor panel data, without the
brightness-dependent gamma, HBM and ELVSS writes. A fixed delay
replaces the vendor's wait on the TCON_RDY pin.

Tested on the tablet: cold and warm boot, hand-off from the bootloader
splash, brightness and blank/unblank. The board DT follows separately.
