Version 3 just adds reviewed-by tags for Krzysztof Kozlowski. Version 2 of this series modifies the first patch only. One section in the description is reworded, and the example now consistenly describes the SC7180 SoC, both as suggested by Krzysztof. 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. -Alex Alex Elder (5): dt-bindings: net: qcom,ipa: deprecate modem-init net: ipa: encapsulate decision about firmware load net: ipa: introduce "qcom,gsi-loader" property dt-bindings: net: qcom,ipa: support skipping GSI firmware load net: ipa: permit GSI firmware loading to be skipped .../devicetree/bindings/net/qcom,ipa.yaml | 78 +++++++++++---- drivers/net/ipa/ipa_main.c | 95 +++++++++++++++---- 2 files changed, 135 insertions(+), 38 deletions(-) -- 2.34.1
