From f262d4ca4b2bf8a99acb37c6151c54cd80251566 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 27 Jan 2020 08:49:47 -0700 Subject: dm: core: Add a way to read platdata for all child devices When generating ACPI tables we need to make sure that all devices have read their platform data, so that they can generate the tables correctly. Rather than adding this code in ACPI, create a core function to handle it.
