Subject: [RFC PATCH v2 06/15] drivers: acpi: iort: enhance device identifiers mappings
Date: Tue, 7 Jun 2016 14:31:01 +0100 [thread overview]
Message-ID: <1465306270-27076-7-git-send-email-lorenzo.pieralisi@arm.com> (raw)
In-Reply-To: <1465306270-27076-1-git-send-email-lorenzo.pieralisi-5wv7dgnIgG8@public.gmane.org>
Current IORT code only allow to map device identifiers to the
corresponding ITS group device id. This is not sufficient, in that
current code does not allow device id mappings to components
that sit between devices and ITS interrupt controllers (eg IOMMUs).
This patch enhances the current IORT ids mapping API to cater for
all mappings allowed by the IORT specification.
