Subject: [PATCH 8/8] drm/panel: Add Samsung S6E3FC2X01 DDIC with AMS641RW
 panel

From: David Heidelberg <david@...t.cz>

Add panel driver used in the OnePlus 6T.

No datasheet, based mostly on EDK2 init sequence and the downstream driver.

Based on work of:
  Casey Connolly <casey@...nolly.tech>
  Joel Selvaraj <foss@...lselvaraj.com>
  Nia Espera <a5b6@...eup.net>
