Subject: [PATCH v5 1/8] clk: tegra: Add PLLP_UD and PLLMB_UD for Tegra210
Date: Tue, 10 Mar 2020 16:19:56 +0100	[thread overview]
Message-ID: <20200310152003.2945170-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200310152003.2945170-1-thierry.reding@gmail.com>

From: Joseph Lo <josephl@nvidia.com>
