[PATCH 1/3] dt-bindings: pfuze100.yaml: Add an entry for interrupts

[PATCH 1/3] dt-bindings: pfuze100.yaml: Add an entry for interrupts

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

The PFUZE100 PMIC has an interrupt pin that can be connected to
the host SoC. Describe it in the dt-bindings to avoid warnings like:

imx6q-zii-rdu2.dtb: pmic@8: 'interrupt-parent', 'interrupts' do not match any of the regexes: 'pinctrl-[0-9]+'
From schema: Documentation/devicetree/bindings/regulator/pfuze100.yaml

[PATCH 2/3] ARM: dts: imx: Use 'pmic' as node name

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Devicetree node names should be generic. Use 'pmic' as node name
to avoid devicetree check warning from pfuze100.yaml.

[PATCH 3/3] ARM: dts: imx6ul-ccimx6ulsom: Remove unexisting PMIC supply

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

There is no "vcoin" supply output provided by the PFUZE100 PMIC.

Remove it to fix the following DT check warning:

imx6ul-ccimx6ulsbcexpress.dtb: pmic@8: regulators: 'vcoin' does not match any of the regexes:

Dumb question, did you spot this only because of dtbs_check, or is this
something you know to be true?
I had the datasheet open to check the interrupt thing, so I figured I
may as well look for coin cell chargers too.
Seemly there is a "licell" pin that is an input/output. Is this what the
vcoin_chg was referring to, or is that something else entirely?

I know nothing about the hardware at all, so was just something that
piqued my curiosity.

Thanks,
Conor.

Thanks for your review.

I have double-checked it and the correct fix is to change it from
"vcoin" to "coin".

I will send a v2 soon.

Thanks
