[PATCH v2 0/2] ARM: dts: qcom: sdx65: support IPA

[PATCH v2 0/2] ARM: dts: qcom: sdx65: support IPA

[Alex Elder]

The upstream IPA driver now supports IPA v5.0 for SDX65.  Add
IPA-related nodes and definitions to "sdx65.dtsi", and enable IPA
in "sdx65-mtp.dts".

Having touched these files, Konrad advised I should update them to
move the "status" property to the end of nodes where it is used.

Version 2 of this series addresses comments made by Krzysztof and
Konrad, and adds their reviewed-by tags.

[PATCH v2 1/2] ARM: dts: qcom: sdx65: add IPA information

[Alex Elder]

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.

[PATCH v2 2/2] ARM: dts: qcom-sdx65: move status properties to end of nodes

[Alex Elder]

Move a few device tree "status" properties so that they are the last
specified property, in "qcom-sdx65-mtp.dts" and "qcom-sdx65.dtsi".
Note that properties must always be specified before sub-nodes.

I'm sorry but building "dtbs" with this change adds a warning
I had not noticed before.
   simple-bus unit address format error

I'll be sending v3 shortly.  Sorry for the noise.
