+Subject: [PATCH 2/2] meson: allow building from shallow clones
+
+When building from shallow clone, tag is not available
+and version defaults to git hash.
+Problem is that some builds check DTC version and fail the comparison.
+Example is https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+Which fails to build with following error:
+dtc version too old (039a994), you need at least version 1.4.4
+
+Drop --always from git describe command, see
+https://github.com/mesonbuild/meson/blob/1.3.0/mesonbuild/utils/universal.py#L773
+This will make it more closer to build via Makefile.
+
+Upstream-Status: Submitted [https://github.com/dgibson/dtc/pull/122]
