Subject: [PATCH v9 1/4] iommu/arm-smmu: move TLB timeout and spin count macros
Date: Tue, 30 Jun 2020 16:57:49 -0700
Message-ID: <20200630235752.8737-2-vdumpa@nvidia.com> (raw)
In-Reply-To: <20200630235752.8737-1-vdumpa@nvidia.com>

Move TLB timeout and spin count macros to header file to
allow using the same values from vendor specific implementations.
