  arm64: dts: qcom: qrb5165-rb5: switch into using GPIO for SPI0 CS (2021-03-18 09:35:42 -0500)

----------------------------------------------------------------
Qualcomm ARM64 DT updates for 5.13

This extends the initial SM8350 description merged in v5.12 with
CPUfreq, SMMU, UFS, RPMHPD, SPMI, USB and remoteproc support. It adds
initial PMIC definitions for the 6 PMICs found on the MTP and it
introduces the new SM8350 Hardware Development Kit (HDK).

SC7180 is further polished, the DisplayPort portion of the QMP phy is
defined and several new SKUs of the Trogdor devices are introduced.

The new SC7280 platform is introduced, with RPMH, RPMHPD, RPMCC, SPMI,
CPU idle, SMMU and watchdog defined.

SDM845 gains the camera related nodes and some cleanups.

For SM8250 it brings some cleanups and migrates SPI0 to use GPIO for
chip select.

I noticed a couple of new warnings from 'make dtbs_check W=1':

Maybe see if you can address these in a follow-up, to avoid regressions.

Merged into arm/dt, thanks!

I saw your other email regarding these and per Rob's request we've
ramped up our effort on cleaning these out. I've however still not
figured out a good way to incorporate the dtbs_check in my patch
handling workflow.

I'm about to send you a another set of pull requests with some more
goodies that was lingering on the list. I will take a look to see if I
can follow up on that with some fixes for above warnings - and take
another look at incorporating dtbs_check in my workflow.

Ok, sounds good. As I mentioned, I'm also just learning how to use
dtbs_check properly. Unfortunately, it takes ages to run on a
non-parallel build,
and using 'make -j32' as I normally do means the output gets reordered
with every run.

It's probably ok if you figure out how to only run it for the files you
actually change in the Qualcomm tree.

Disabling all non-Qualcomm arches makes `make dtbs_check` a little bit
less painful.

Yes, this is a trick I'm applying as well.

It would however be nice if one didn't have to disable CONFIG_ARCH_* to
achieve this, or even better if one could run dtbs_check on a single
.dtb. In particular since many of the warnings are resolved by fixing
the bindings, which causes dtbs_check to recheck all files.

As a quick hack: add the following rule to the top-level Makefile:

%.dt.yaml: include/config/kernel.release scripts_dtc
        $(Q)$(MAKE) $(build)=Documentation/devicetree/bindings
Documentation/devicetree/bindings/processed-schema.json
        $(Q)$(MAKE) $(build)=$(dtstree) $(dtstree)/$@ CHECK_DTBS=y

Now you can run checks for a single device tree by running 'make
ARCH=arm64 ...... sdm845-db845.dy.yaml'

I don't know if it's worth including this into the upstream source tree.
