Subject: [PATCH 0/2] Preserve the flags portion on 1:1 dma-ranges mapping
Date: Fri, 8 Nov 2024 11:39:19 +0100 [thread overview]
Message-ID: <cover.1731060031.git.andrea.porta@suse.com> (raw)
Empty dma-ranges in DT nodes using 3-cell address spcifier cause the
flag portion to be dropped by of_translate_one(), failing the translation
chain. This patch aims at fixing this issue.
Part of this patchset was originally preparatory for a bigger patchset
(see [1]). It has been split in a standalone one for better management
and because it contains a bugfix which is probably of interest to stable
branch.
I've also added new tests to unittest to prove it.
Many thanks,
Andrea
