[PATCH v2 1/7] arm64: dts: qcom: sc7180: Explicitly describe the IPA IMEM slice

From: Konrad Dybcio

Date: Thu Mar 05 2026 - 06:01:23 EST


From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

As part of stepping away from crazy hardcoding in the driver, move
define the slice explicitly and pass it to the IPA node.
