From bde5e7a632ef06b16ea77af037c1442e10949666 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 11 Jan 2018 11:59:39 +0100 Subject: kernel: backport mtd implementation for "compatible" in "partitions" subnode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This backports upstream support for "compatible" DT property set for the "partitions" subnode of flash node. It allows specifying how partitions should be created/parsed. Right now only "fixed-partitions" is supported. It should eventually replace our downstream "linux,part-probe" solution.
