Subject: [PATCH net-next 0/5] net: ipa: change GSI firmware load specification

Currently, GSI firmware must be loaded for IPA before it can be
used--either by the modem, or by the AP.  New hardware supports a
third option, with the bootloader taking responsibility for loading
GSI firmware.  In that case, neither the AP nor the modem needs to
do that.

The first patch in this series deprecates the "modem-init" Device
Tree property in the IPA binding, using a new "qcom,gsi-loader"
property instead.  The second and third implement logic in the code
to support either the "old" or the "new" way of specifying how GSI
firmware is loaded.

The last two patches implement a new value for the "qcom,gsi-loader"
property.  If the value is "skip", neither the AP nor modem needs to
load the GSI firmware.  The first of these patches implements the
change in the IPA binding; the second implements it in the code.
