Subject: [PATCH 2/3] PCI: rcar: Allow 64bit MSI addresses
Date: Sun, 17 Mar 2019 01:06:07 +0100 [thread overview]
Message-ID: <20190317000608.24881-2-marek.vasut@gmail.com> (raw)
In-Reply-To: <20190317000608.24881-1-marek.vasut@gmail.com>
From: Marek Vasut <marek.vasut+renesas@gmail.com>
The MSI address can be 64bit. Switch the data type used to hold the
result of virt_to_phys() to phys_addr_t to reflect it's properties
correctly and program the top 32bits of PA into PCIEMSIAUR.
