This series includes four updates to DTS files for Qualcomm SoCs
that include IPA.
Most of this series was posted once before, and accepted into the
net-next/master branch by David Miller:
https://lore.kernel.org/netdev/[email protected]/
That series got reverted yesterday, meaning these patches can be
taken in through the Qualcomm tree as intended:
https://lore.kernel.org/netdev/[email protected]/
The first patch defines IPA information for the SC7280 SoC. The
second enables IPA for the SC7280 IDP platform, indicating the
modem should perform early IPA initialization.
The third patch adds the definition of a reserved memory area to
hold IPA firmware for the SC7180 SoC; this is used if the modem does
*not* do early IPA initialization.
And the last patch fixes the definitions used for interconnects for
the SM8350 SoC. A corresponding update to the configuration data
(IPA code) was posted earlier today:
