[PATCH v4 0/2 RESEND] Fix pm8941-misc extcon interrupt dependency assumptions

[Bryan O'Donoghue]

V4:
- Added suggested extra log text from Marjin to extcon patch

V3:
- Adds a cover-letter since we are now doing two patches a dt-bindings fix and
  platform_get_irq_byname_optional fix.
- Add Review-by -> Rob Herring, Marijn Suijten
- Add additional patch to negate warning when one of usb_id or usb_vbus
  is not declared in the platform DTS.

[PATCH v4 1/2 RESEND] dt-bindings: pm8941-misc: Fix usb_id and usb_vbus definitions

[Bryan O'Donoghue]

dts validation is throwing an error for me on 8916 and 8939 with
extcon@1300. In that case we have usb_vbus but not usb_id.

It wasn't immediately obvious if there was a valid use-case for the
existing code for usb_id in isolation, however discussing further, we
concluded that usb_id, usb_vbus or (usb_id | usb_vbus) are valid
combinations as an external IC may be responsible for usb_id or usb_vbus.

Expand the definition with anyOf to capture the three different valid
modes.

[PATCH v4 2/2 RESEND] extcon: qcom-spmi: Switch to platform_get_irq_byname_optional

[Bryan O'Donoghue]

Valid configurations for the extcon interrupt declarations are

- usb_id
- usb_vbus
- (usb_id | usb_vbus)

In the case of a standalone usb_id or usb_vbus failure to find one of the
interrupts shouldn't generate a warning message. A warning is already in
place if both IRQs are missing.

Switch to using platform_get_irq_byname_optional() in order to facilitate
this behaviour.

(Whoops, I didn't get CC'd in the cover letter - downloaded it from the

It seems it made it to the lists successfully - there's a v4 RESEND from
the 8th: https://lore.kernel.org/linux-arm-msm/20220908112556.860343-1-bryan.odonoghue@linaro.org/

Thanks for bumping this Luca.

I was about to do just that.

Chanwoo - would appreciate merging this, its an annoying and very old 
dts splat for us.
