Subject: [PATCH 14/17] clk: tegra: Add Tegra210B01 support
From: Aaron Kling <webgeek1234@...il.com>
This is based on the downstream Nvidia 5.10 kernel. That version was
semi-integrated into the Tegra210 clock driver. Looking at the existing
Tegra210 support, it made more sense to make this a fully independent
driver, so that is implemented here.
