Subject: [PATCH v5 7/8] arm64: tegra: Add external memory controller node for Tegra210
Date: Tue, 10 Mar 2020 16:20:02 +0100	[thread overview]
Message-ID: <20200310152003.2945170-8-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200310152003.2945170-1-thierry.reding@gmail.com>

From: Joseph Lo <josephl@nvidia.com>

Add external memory controller (EMC) node for Tegra210

Signed-off-by: Joseph Lo <josephl@nvidia.com>
Signed-off-by: Thierry Reding <treding@nvidia.com>
---
Changes in v5:
- drop list of clocks because we need very strict ordering that DT can't
  guarantee
- drop hard-coded EMC table, bootloaders should add it dynamically
