Subject: [PATCH V7 0/6] dt: build overlays
Date: Fri, 29 Jan 2021 12:54:04 +0530 [thread overview]
Message-ID: <cover.1611904394.git.viresh.kumar@linaro.org> (raw)
Hi,
This patchset makes necessary changes to the kernel to add support for
building overlays (%.dtbo) and the required fdtoverlay tool. This also
builds static_test.dtb using most of the existing overlay tests present
in drivers/of/unittest-data/ for better test coverage.
Note that in order for anyone to test this stuff, you need to manually
run the ./update-dtc-source.sh script once to fetch the necessary
changes from the external DTC project (i.e. fdtoverlay.c and this[1]
patch).
I have tested this patchset for static and runtime testing (on Hikey
board) and no issues were reported.
V7:
- Add a comment in scripts/dtc/Makefile
- Add Ack from Masahiro for patch 4/6.
- Drop word "merge" from commit log of 2/6.
- Split apply_static_overlay, static_test.dtb, and static_base.dts into
two parts to handle overlay_base.dts and testcases.dts separately.
V6:
- Create separate rules for dtbo-s and separate entries in .gitignore in
4/6 (Masahiro).
- A new file layout for handling all overlays for existing and new tests
5/6 (Frank).
- Include overlay.dts as well now in 6/6 (Frank).
V5:
- Don't reuse DTC_SOURCE for fdtoverlay.c in patch 1/5 (Frank).
- Update .gitignore and scripts/Makefile.dtbinst, drop dtbo-y syntax and
DTC_FLAGS += -@ in patch 4/5 (Masahiro).
- Remove the intermediate dtb, rename output to static_test.dtb, don't
use overlay.dtb and overlay_base.dtb for static builds, improved
layout/comments in Makefile for patch 5/5 (Frank).
