[PATCH v2 3/3] riscv: dts: mpfs: migrate to OF_UPSTREAM
Conor Dooley
conor at kernel.org
Wed Oct 23 12:17:54 CEST 2024
From: Conor Dooley <conor.dooley at microchip.com>
The U-Boot copy of the mpfs devicetree has, in general, been neglected
somewhat in comparison to the one in Linux. Moving to OF_UPSTREAM to
keep both in sync should serve to eliminate that discrepancy.
Additionally, moving to OF_UPSTREAM will let U-Boot automatically pick
up the devicetree rework that is in progress at [1].
