Subject: [PATCH v2 0/4] PCI: dwc: Clean up iatu index mess
Date: Thu, 22 Jan 2026 23:29:14 +0100 [thread overview]
Message-ID: <20260122222914.523238-6-cassel@kernel.org> (raw)
This series tries to clean up the iatu index mess, by treating
iatu indexing for outbound and inbound address translation in
a consistent way (increment the index after assignment, and only
if the function call succeeded).
Changes since v1:
-Added patch 4/4 from Krishna which fixes iatu indexing when using ECAM.
I've adapted the patch to my clean up series and fixed some bugs.
Link to v1:
