Subject: [PATCH v3 01/10] dt-bindings: iio: dac: adi-axi-adc: fix ad7606
 pwm-names

From: Angelo Dureghello <adureghello@...libre.com>

Fix make dt_binding_check warning:

DTC [C] Documentation/devicetree/bindings/iio/adc/adi,axi-adc.example.dtb
.../adc/adi,axi-adc.example.dtb: adc@0: pwm-names: ['convst1'] is too short
    from schema $id: http://devicetree.org/schemas/iio/adc/adi,ad7606.yaml#

Add "minItems" to pwm-names, it allows to use one single pwm when
connected to both adc conversion inputs.

Fixes: 7c2357b10490 ("dt-bindings: iio: adc: ad7606: Add iio backend bindings")
