Subject: arm64: dts: renesas: r8a77970: Update IPMMU DS1 bit number
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d2b860cb303fdeffa886c20bfbdbfd88cc52c85f;p=openwrt%2Fstaging%2Fblogic.git

arm64: dts: renesas: r8a77970: Update IPMMU DS1 bit number

Judging by "R-Car-Gen3-rev0.80" IPMMU IMSSTR register documentation
for [R-Car V3M] the DS1 bit field should be bit 0.

Update the ipmmu-main property to make it match the data sheet.
