Subject: [PATCH v2 09/12] memory: tegra: Only initialize reset controller if available
Date: Tue,  1 Jun 2021 19:59:39 +0200	[thread overview]
Message-ID: <20210601175942.1920588-10-thierry.reding@gmail.com> (raw)
In-Reply-To: <20210601175942.1920588-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

The memory controller hot resets are implemented in the BPMP on Tegra186
and later, so there's no need to provide an implementation via the
memory controller driver. Conditionally register the reset controller
only if needed.
