Subject: [PATCH v5 4/6] PCI: uniphier: Add iATU register support
Date: Thu, 18 Jun 2020 17:38:11 +0900 [thread overview]
Message-ID: <1592469493-1549-5-git-send-email-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <1592469493-1549-1-git-send-email-hayashi.kunihiko@socionext.com>
This gets iATU register area from reg property. In Synopsys DWC version
4.80 or later, since iATU register area is separated from core register
area, this area is necessary to get from DT independently.
