From 93d2e4322aa74c1ad1e8c2160608eb9a960d69ff Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Thu, 14 May 2020 22:35:00 -0700 Subject: of: platform: Batch fwnode parsing when adding all top level devices The fw_devlink_pause() and fw_devlink_resume() APIs allow batching the parsing of the device tree nodes when a lot of devices are added. This will significantly cut down parsing time (as much a 1 second on some systems). So, use them when adding devices for all the top level device tree nodes in a system.
