[PATCH 0/6] arm64: dts: qcom: Get rid of some warnings

[Vinod Koul]

This attempts to make W=1 free from warnings for all SM* dts files.

Bunch of these are releated to node not having valid unit address and being
present under soc node. So moving it out fixed that. Interconnect node was
simple rename to remove unit address which was not really valid for these
nodes.

[PATCH 1/6] arm64: dts: qcom: sm8450: rename interconnect nodes

[Vinod Koul]

clk-virt and mc-virt interconnect nodes were named interconnect@0 and
interconnect@1. That is incorrect as we don't have unit addresses 0/1
for these node.

This causes warning:
arch/arm64/boot/dts/qcom/sm8450.dtsi:255.27-259.4:
	Warning (unit_address_vs_reg): /interconnect@0:
	node has a unit name, but no reg or ranges property
arch/arm64/boot/dts/qcom/sm8450.dtsi:261.26-265.4:
	Warning (unit_address_vs_reg): /interconnect@1:
	node has a unit name, but no reg or ranges property
arch/arm64/boot/dts/qcom/sm8450.dtsi:255.27-259.4:
	Warning (unique_unit_address_if_enabled): /interconnect@0:
	duplicate unit-address (also used in node /soc@0)

Rename the nodes to interconnect-0 and interconnect-1 to fix the
warning.

I don't know the SM8250, but usually the sound node (e.g. containing
audio-codec) is not part of SoC. I propose to remove it entirely from
DTSI and define in same place in each DTS. It makes more sense logically
in such case - one clearly see which board defines the sounds, which
does not.

This probably should be under "sound" node. Anyway having it under soc
seemed incorrect.

I actually wonder where this wcd9380 sits? What type of bus?

I think this needs different fix and my review was not correct. MIPI DSI
is a bus, so it can have children with unit addresses.

This DTSI (and several others) should have address/size cells, so
downstream could add easily children (e.g. panel nodes).

However I don't know how to combine it with "ports" not having unit address.

Maybe Rob has some ideas?

yeah it might make sense to be under sound. I think this is a slimbus

Most of our boards have sound, should we duplicate it in all the

wcd938x can be moved out of soc node but not under sound as it is.

If we plan to move external codecs under sound node then sound node has 
to be converted in to a simple-bus I guess. If we do that we have to 
make sure that we are consistent across all the qcom dts. This does 
sound correct either.

Currently sound node is only used for sound-card, sound card uses LPASS 
IP which is part of SoC along with external or internal codecs.

I am not 100% sure moving aggregate devices like sound card which uses 
SoC components along with external components out of soc node is the 
right choice.

Moving sound out of soc node might also add some regressions as sound 
device is sometimes used to allocate dma memory, so we have to be 
careful with this move.

The reason why sound node is empty in SoC is because the wiring of dais 
are board specific. We could add compatible string to soc sound node if 
that helps clear some confusion.

WCD938x codec has two parts wcd938x-tx and wcd938x-rx which are under 
there respective SoundWire bus.

We can not move wcd938x-tx and wcd938x-rx out of there bus nodes which 
result with no device enumeration.

But is the sndcard platform or device specific? E.g. all the SDM845
boards seems to use either qcom,sdm845-sndcard or qcom,db845c-sndcard.

Are there room for some common properties in this node?


Otherwise it seems reasonable to skip it in the platform dtsi.
