Subject: Re: [PATCH v2 2/5] ARM: dts: add Protonic PRTI6Q board
Hi Oleksij,
thanks for your patche. In general you should use generic node names,
sort the properties, nodes, phandles correctly except the iomux node.
Finally, pls don't mix dts and dtsi files. If the dts needs the iomux
than pls mux it within the dts file :) Pls see my comments below.

Does npd mean no-power-down?

The "compatible" property should be the 1st property.

Please sort all nodes and phandles alphabetical, this applies to all
your .dts(i) files except the iomux node. I saw some dt files moving
that node to the end. @Shawn is this a unwritten rule?

Where is this phandle used? Please name the node more generic e.g. like
the phandle and drop the phandle if not used.

The "reg" property should be listed after the "compatible" property.

Here we are mixing dtsi and dts files and the dtsi is not self-contained
anymore. This isn't a good idea.

Most of the node is already defined in your dtsi file and again
mixing dtsi and dts file. Pls check that for all your files. I
would mux the common things like miso,mosi,clk within the dtsi and the
cs signals here. Also we can use the phandle to extend the node.

Why is this node needed? We only add the IRQ line. You only need to use
the phandle to extend the node or add a new wl1271grp. I would prefer
the 2nd.
