Subject: arm64: dts: sdm845: add IPA iommus property
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e9e89c45bfeb0d6196cd318d5e9231a211684d33;p=linux.git

arm64: dts: sdm845: add IPA iommus property

Add an "iommus" property to the IPA node in "sdm845.dtsi".  It is
required because there are two regions of memory the IPA accesses
through an SMMU.  The next few patches define and map those regions.
