Subject: [alsa-devel] [PATCH v3 01/15] dt-bindings: soc: tegra-pmc: Add Tegra PMC clock bindings
Date: Thu, 5 Dec 2019 18:48:41 -0800 [thread overview]
Message-ID: <1575600535-26877-2-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1575600535-26877-1-git-send-email-skomatineni@nvidia.com>
Tegra PMC has clk_out_1, clk_out_2, clk_out_3 clocks and each of
these clocks has mux and a gate as a part of PMC controller.
This patch documents PMC clock bindings and adds a header defining
Tegra PMC clock ids.

+Tegra PMC has 3 clocks clk_1, clk_2 and clk_3. Each of these clocks has
