Subject: arm64: dts: imx8mp: Disable dsp reserved memory by default
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=010dc015b811a4e715a25273df2e357fa099de24;p=linux.git

arm64: dts: imx8mp: Disable dsp reserved memory by default

Even if the 'dsp' node is disabled the memory intended to be used by the
DSP is reserved. This limits the memory range suitable for CMA allocation.
Thus disable the dsp_reserved node. DSP users need to enable it in parallel
to the 'dsp' node.
