[PATCH 1/2] ARM: dts: qcom: sdx65: add IPA information

Alex Elder
2023-03-24T20:16:45Z

Add IPA-related nodes and definitions to "sdx65.dtsi". The SMP2P
nodes (ipa_smp2p_out and ipa_smp2p_in) are already present.

Enable IPA in "sdx65-mtp.dts"; this GSI firmware is loaded by Trust
Zone on this platform.
