Subject: [PATCH 3/4] PCI: tegra: Set DesignWare IP version
Date: Mon, 26 Oct 2020 12:24:58 +0530
Message-ID: <20201026065459.28509-4-vidyas@nvidia.com> (raw)
In-Reply-To: <20201026065459.28509-1-vidyas@nvidia.com>

Set the DesignWare IP version for Tegra194 to 0x490A. This would be used
by the DesigWare sub-system to do any version specific configuration
(Ex:- TD bit programming for ECRC).
