Subject: [PATCH V4 2/8] clk: tegra: Add PLLP_UD and PLLMB_UD for Tegra210
Date: Wed, 29 May 2019 16:21:33 +0800	[thread overview]
Message-ID: <20190529082139.5581-3-josephl@nvidia.com> (raw)
In-Reply-To: <20190529082139.5581-1-josephl@nvidia.com>

Introduce the low jitter path of PLLP and PLLMB which can be used as EMC
clock source.
