[PATCH 1/5] arm64: dts: freescale: Import optee node from u-boot device trees

flat view
STALE104d SUPERSEDED

From: Mathieu Dubois-Briand <mathieu.dubois-briand@bootlin.com>
Date: 2026-07-10 15:32:16
Also in: imx, linux-arm-kernel, lkml, openbmc
Subsystem: arm/freescale imx / mxc / layerscape arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

Revision v1 of 2 in this series.

  1. v1 current
  2. v2 [diff vs current] 
U-Boot is importing kernel device trees for these platforms, but adding
a firmware node to enable communication with OP-TEE. Importing
changes here will allow to remove these additions in U-Boot.
