From c464cc610f51f6eb5f27bf905d4c1ab1896b2725 Mon Sep 17 00:00:00 2001 From: Olivier Moysan Date: Tue, 30 Jul 2024 10:46:33 +0200 Subject: iio: add child nodes support in iio backend framework Add an API to support IIO generic channels binding: http://devicetree.org/schemas/iio/adc/adc.yaml# This new API is needed, as generic channel DT node isn't populated as a device. Add devm_iio_backend_fwnode_get() to allow an IIO device backend consumer to reference backend phandles in its child nodes.
