[v2] Rework Nomadik GPIO to add Mobileye EyeQ5 support

[PATCH v2 02/30] dt-bindings: gpio: nomadik: add optional ngpios property

Posted by Théo Lebrun 1 year, 11 months ago

This GPIO controller can support a lesser number of GPIOs than 32.
Express that in devicetree using an optional, generic property.
