Subject: arm64: dts: ti: k3-j721e: Enable C6x DSP nodes at the board level
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=00ae4c39cd16ef8b1662c5915dda08eb28eed762;p=linux.git

arm64: dts: ti: k3-j721e: Enable C6x DSP nodes at the board level

C6x DSP nodes defined in the top-level J721e SoC dtsi files are incomplete
and will not be functional unless they are extended with both mboxes and
memory-region information.

As theses only known about at the board integration level, these nodes
should only be enabled when provided with this information.

Disable the C6x DSP nodes in the dtsi files and only enable the ones that
are given the required mboxes and memory-region on a given board.
