From 60ea6f00c57dae5e7ba2c52ed407cb24fdb11ebe Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 6 Jan 2023 07:25:01 -0600 Subject: [PATCH] net: ipa: correct IPA v4.7 IMEM offset Commit b310de784bacd ("net: ipa: add IPA v4.7 support") was merged despite an unresolved comment made by Konrad Dybcio. Konrad observed that the IMEM region specified for IPA v4.7 did not match that used downstream for the SM7225 SoC. In "lagoon.dtsi" present in a Sony Xperia source tree, a ipa_smmu_ap node was defined with a "qcom,additional-mapping" property that defined the IPA IMEM area starting at offset 0x146a8000 (not 0x146a9000 that was committed). The IPA v4.7 target system used for testing uses the SM7225 SoC, so we'll adhere what the downstream code specifies is the address of the IMEM region used for IPA.
