[PATCH 1/2] ARM: dts: qcom: ipq4019-ap.dk01.1: use existing labels for nodes

[Robert Marko]

All of the nodes under soc already have existing labels so use those
instead.

[PATCH 2/2] ARM: dts: qcom: ipq4019-ap.dk01.1: align flash node with bindings

[Robert Marko]

Rename the SPI-NOR node to flash@0, remove #address-cells and #size-cells
as they should be under the partitions subnode and use the generic
jedec,spi-nor compatible.

You can also do "nandmanufacturer,mx25l25635e", "jedec,spi-nor"

Hi,
I grepped the vendor U-Boot to make sure it's not being triggered off
the mx25l25635e
compatible but the only hit is the IC support itself.
MX25L25635 was just the original NOR IC Qualcomm used on the board so
to me it made
most sense to just use the JEDEC compatible as NOR itself is JEDEC NOR
compatible.

Regards,
Robert

OK if dynamic identification works fine

It should work fine, datasheet is clear that its JEDEC compatible.
That being said, I dont actually have the board, just figured it was
time for a cleanup as
OpenWrt has been patching DK01 and DK04 for ages.

Hm. Do we know whether there are still users of this boards?

I honestly doubt it as they have been broken in OpenWrt for years and
nobody complained.
So we are currently removing support for them, but I still wanted to
at least fixup the DTS state
upstream.
These boards are not obtainable anymore.

I also noticed they were detached from the other snapdragons in u-boot
for no good reason (at first glance anyway).

If we don't get any hands up from users, I think deprecation is in order.

If you are talking about the mainline U-Boot then yeah, my basic port was done
years ago and I knew way less about the SoC then now.
Currently its on my TODO to merge them with Snapdragon and add some proper
GPIO and pinctrl drivers as well as using the Linux DTS.

Take a look at this branch of mine [1], I already did some of that.

If you wish to upstream that, please coordinate with Caleb (+CC) who
may be interested in the same in parallel.

That is great, though this is very low hanging fruit for me, I have
plenty more of IPQ807x
stuff that needs to make its way upstream.

dtx_diff returns an empty diff, nice

Couple further suggestions:

- wdog can probably enabled unconditionally
- same for blsp dma since there's only one host so it must be
  used by something
- same for crypto engine as it's a common piece of hw
- you can drop mux{}, pinmux{}, pinconf{} from pin nodes, just add
  the properties directly under the pin nodes
- this devicetree could use some schema warnings cleanup (make dtbs_check
  plus things like no underscores in node names)

Hi,
Yeah, I am planning a follow-up to clean up the pinctrl and most of
the stuff you mentioned
for the SoC DTSI itself.
I wanted to keep the diff clean here and just use the labels.
