Subject: [PATCH net-next] net: ipa: fix IPA v4.11 interconnect data
Date: Mon, 19 Jul 2021 15:23:33 -0500 [thread overview]
Message-ID: <20210719202333.3067361-1-elder@linaro.org> (raw)
Currently three interconnects are defined for the Qualcomm SC7280
SoC, but this was based on a misunderstanding. There should only be
two interconnects defined: one between the IPA and system memory;
and another between the AP and IPA config space. The bandwidths
defined for the memory and config interconnects do not match what I
understand to be proper values, so update these.
