Subject: ARM: dts: renesas: Add Renesas R8A779H0 V4M DT extras
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=903f98e88cce3971d1df1c85e29379cc875ee35f;p=u-boot.git

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.
