From 903e83ee84649c1a70bfd8b9ec84dacb8c24e7cb Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 27 Jan 2020 08:49:48 -0700 Subject: dm: core: Add a way to iterate through children, probing each It is sometimes useful to process all children, making sure they are probed first. Add functions to help with this and a macro to make it more convenient.
