From d392d32fd8d5fb28cd5c5888cd303e57a507dda9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 3 Feb 2021 06:01:21 -0700 Subject: [PATCH] dtoc: Generate device instances Add support for generating a file containing udevice instances. This avoids the need to create these at run time. Update a test uclass to include a 'per_device_plat_auto' member, to increase test coverage. Add another tab to the driver_info output so it lines up nicely like the device-instance output.
