From 73981390dfea84b2861d285b2d1b2fd33a84b665 Mon Sep 17 00:00:00 2001 From: Sughosh Ganu Date: Fri, 21 Oct 2022 18:15:54 +0530 Subject: dt/bindings: Add bindings for GPT based FWU Metadata storage device Add bindings needed for accessing the FWU metadata partitions. These include the compatible string which point to the access method and the actual device which stores the FWU metadata. The current patch adds basic bindings needed for accessing the metadata structure on GPT partitioned block devices.
