From 903f98e88cce3971d1df1c85e29379cc875ee35f Mon Sep 17 00:00:00 2001 From: Hai Pham Date: Sun, 28 Jan 2024 16:52:07 +0100 Subject: [PATCH] ARM: dts: renesas: Add Renesas R8A779H0 V4M DT extras Add Renesas R8A779H0 V4M DT extras for U-Boot. Until the RPC node becomes part of main DT, keep it here as an extension so that board code can enable and use the RPC to access SPI NOR.
