Grab IPA IMEM slice through DT, part 2

[PATCH 06/10] arm64: dts: qcom: sdm845: Explicitly describe the IPA IMEM slice

Posted by Konrad Dybcio 6 months, 3 weeks ago

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

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