[PATCH v2 0/2] arm64: dts: qcom: sm6350: enable IPA

[Alex Elder]

Enable IPA for the SM6350 SoC, which implements IPA v4.7.  Enable it
on the Fairphone 4, which incorporates IPA definitions used for the
SM6350.

Version 2 of this series uses the new "qcom,gsi-loader" property to
specify that the AP should load firmware on this platform.
