Subject: [PATCH AUTOSEL 5.4 13/35] ARM: dts: dra7: Add "dma-ranges" property to PCIe RC DT nodes
Date: Sun, 15 Mar 2020 22:33:49 -0400 [thread overview]
Message-ID: <20200316023411.1263-13-sashal@kernel.org> (raw)
In-Reply-To: <20200316023411.1263-1-sashal@kernel.org>
From: Kishon Vijay Abraham I <kishon@ti.com>
[ Upstream commit 27f13774654ea6bd0b6fc9b97cce8d19e5735661 ]
'dma-ranges' in a PCI bridge node does correctly set dma masks for PCI
devices not described in the DT. Certain DRA7 platforms (e.g., DRA76)
has RAM above 32-bit boundary (accessible with LPAE config) though the
PCIe bridge will be able to access only 32-bits. Add 'dma-ranges'
property in PCIe RC DT nodes to indicate the host bridge can access
only 32 bits.
