Subject: [PATCH v2 12/14] soc/tegra: pmc: Add Tegra234 support
Date: Thu, 17 Sep 2020 12:07:50 +0200	[thread overview]
Message-ID: <20200917100752.3516153-13-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200917100752.3516153-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

The PMC block is largely similar to that found on earlier chips, but
not completely compatible. Allow binding to the instantiation found on
Tegra234.
