Subject: [PATCH v1 15/17] dt-bindings: tegra186-pmc: Add Tegra PMC clock bindings
Date: Mon, 18 Nov 2019 22:50:32 -0800 [thread overview]
Message-ID: <1574146234-3871-16-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1574146234-3871-1-git-send-email-skomatineni@nvidia.com>
Document clock bindings for pmc clocks clk_out_1, clk_out_2 and clk_out_3.
These clocks are part of Tegra PMC block and pmc node is the provider for
these clocks.

+== Clock Control ==
+
+Tegra PMC has 3 clocks clk_1, clk_2 and clk_3. Each of these clocks has
+source selection and enable/disable gate.
+Parent/source for these clocks can be either of clk_m, clk_m_div2, clk_m_div4,
+or extern clock from Tegra CAR module.
+
+Clock configuration example:
+ pmc: pmc@7000e400 {
+ compatible = "nvidia,tegra186-pmc";
+ reg = <0 0x0c360000 0 0x10000>,
