Subject: [PATCH v8 07/22] dt-bindings: soc: tegra-pmc: Add Tegra PMC clock bindings
Date: Mon, 13 Jan 2020 23:24:12 -0800
Message-ID: <1578986667-16041-8-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1578986667-16041-1-git-send-email-skomatineni@nvidia.com>

Tegra PMC has 3 clocks clk_out_1, clk_out_2, and clk_out_3.

This patch documents PMC clock bindings and adds a header defining
Tegra PMC clock ids.
