Subject: [PATCH v2 1/2] acpica: iort: Update SMMUv3 header for proximity domain mapping
Date: Tue,  6 Jun 2017 16:17:44 +0530	[thread overview]
Message-ID: <1496746065-11082-2-git-send-email-ganapatrao.kulkarni@cavium.com> (raw)
In-Reply-To: <1496746065-11082-1-git-send-email-ganapatrao.kulkarni@cavium.com>

ARM IORT specification (rev. C) has added two new fields to define
proximity domain for the SMMUv3 node in the IORT table.

Proximity Domain Valid:
	Set to 1 if the value provided in the Proximity Domain field is
	valid. Set to 0 otherwise.

Proximity domain:
	If the Proximity Domain Valid flag is set to 1, this entry
	provides the proximity domain to which this SMMU
	instance belongs.

Update header file to reflect this.
