The final value in this interrupts property means IRQ_TYPE_NONE.

A WARN_ON() was added early this year to complain about use of
IRQ_TYPE_NONE: 83a86fbb5b56 "irqchip/gic: Loudly complain about
the use of IRQ_TYPE_NONE", resulting in many warnings spewing
forth when I boot an APQ8074 Dragonboard.  I am trying to
determine whether the warning is overly aggressive, or whether
the IRQ TYPE is incorrectly specified for the spmi node.

The interrupt-parent for the spmi node is intc: interrupt-controller@f9000000,
which has compatible = "qcom,msm-qgic2".  I do not know the architecture
or implementation of this interrupt controller.  Is an IRQ_TYPE_NONE
valid in this case, or should a specific type be provided?

Thanks!

-Frank

Hi All,

The email for Ivan is no longer valid.  Can anyone else help me with
my question?

No, IRQ_TYPE_NONE isn't valid and the WARN_ON() is reasonable.

Please change it to IRQ_TYPE_LEVEL_HIGH. And while you're at it, replace
the first 0 with GIC_SPI.


If you have more of these warnings you can most likely look at e.g.
msm8916 (arm64) to find the right flags.

Bjorn

PMA8084 have 2 SPMI devices per physical package. Add their
configuration nodes and include them in boards which are using
AQP8084 based chipset.

Looks fine.

Can you please put the specific compatible strings for the pmic model
into the nodes in addition to the generic "qcom,spmi-pmic"? We may want
to have regmap config tables in the future that describe the
cache/read/write abilities of the regsiters. If all we have is the
generic binding then we don't have a way to populate these tables.
Unless the plan there is to use the revid registers?

Hi Stephan, 

Sorry for delayed answer.

I would really like that we can use "revid" registers, but I don't know... 

>From what I can see usually in one physical PMIC chip they
are 2 USID devices.

I can successfully discover following USID's on APQ8074 boards:

pmic-spmi 0-00: qcom,pm8941-v1.0 detected
pmic-spmi 0-01: qcom,pm8941-v1.0 detected
pmic-spmi 0-04: qcom,pm8841-v0.0 detected
pmic-spmi 0-05: qcom,pm8841-v0.0 detected

Unfortunately on PM8916 only one device is detected, with USID 0.
But they should be two, judging by downstream DTS files, right?

pmic-spmi 0-00: qcom,pm8916-v0.0 detected 
pmic-spmi 0-01: unknown device

For communication with PM8916 I am using recent patches from Gilad [1].
Maybe there are still some issues with these patches, which can cause
this behavior or PM8916 just didn't have these registers for USID 1?

Regards,
Ivan

Hmm... do you have 4 total rev-id nodes on apq8074? I only see
one rev-id node per pmic (2 total), so I'm a little lost how the
correct pmic version is detected on the 0-01 and 0-05 devices in
your example above. Maybe I've missed something though, I'll have
to check in a few hours when I'm in the office.

Same confusion here. I am using this[1] patch to read revision info.

Address at offset 0x105 for USID 0,1 on PM8914 and USID 4,5 on PM8841
contains 0x51, which denotes them as PMIC's, so patch assumes that rest
of the registers have to contain valid version values.

Ivan
