Subject: [PATCH] drm/panel-edp: Add BOE NE140WUM-N41 (0x0d9b) panel
Date: Wed, 14 Oct 2026 17:50:35 -0600	[thread overview]
Message-ID: <20261014235035.1731419-1-luke@phorex.org> (raw)

The Lenovo ThinkPad T14s Gen 7 (Snapdragon X2 Elite) uses this 14"
1920x1200 panel. Without an entry panel-edp warns at every boot ("Unknown
panel BOE 0x0d9b, using conservative timings").

The panel's timing requirements are not published, so use the same delays
as the other BOE NE140WUM entries (delay_200_500_e80). With them the panel
trains and lights up reliably on this machine.
