Subject: [PATCH v4 0/4] PCI: dwc: Clean up iATU index mess
Date: Fri, 23 Jan 2026 19:28:35 +0100 [thread overview]
Message-ID: <20260123182835.831710-6-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 v3:
-The ECAM config space accessors do not support cfg0_io_shared, thus if
running in ECAM mode, and we are out of outbound iATUs, return an error
instead of enabling the cfg0_io_shared feature.
Link to v3:
