  Cc: devicetree, robh+dt, Daniel Mack, linux-arm-kernel

This patch adds a set of DTS files that support all PXA3xx based Raumfeld
audio hardware devices.

Common nodes are factored out into 'common' and 'tuneable-clock' include
files to keep the top-level DTS files smaller.

* [PATCH] ARM: dts: pxa3xx: Add Raumfeld DTS files
@ 2018-11-05 19:40 ` Daniel Mack
  0 siblings, 0 replies; 12+ messages in thread
From: Daniel Mack @ 2018-11-05 19:40 UTC (permalink / raw)
  To: linux-arm-kernel

This patch adds a set of DTS files that support all PXA3xx based Raumfeld
audio hardware devices.

Common nodes are factored out into 'common' and 'tuneable-clock' include
files to keep the top-level DTS files smaller.

Hi Daniel,

I will need someone from the devicetree to ack this one, Rob or anybody
maintaining the devicetree.

Rob, Mark, would you be so kind as to have a look at this patch, I have no
concerns taking it into the pxa/dt tree, but I'd rather be safe with someone
from the devicetree maintainers reviewing it first.

You can drop console since you have stdout-path.

Don't need this.

Why do we have this when we can just get the length of cs-gpios?

Drop the unit-address as there is no reg property. Build your DT with
W=12 and fix any new warnings these new files add (probably some are
from the SoC dtsi).

You can drop console since you have stdout-path.

Don't need this.

Why do we have this when we can just get the length of cs-gpios?

I happened to see this, but generally I don't have the bandwidth to
review all the dts files. The subsystem maintainers have to do this.
For starters, just make sure new dts files aren't adding new warnings
when built with W=1 or W=12. This will be easier if the base SoC dtsi
files build cleanly.

That's a good question, but for now, the driver requires the node to be 
there. It can probably be cleaned up by a separate series.

This hint helped a lot. I've fixed numerous smaller problems in the SoC 
dtsi and will submit them together with a v2 of this patch.
