38 Tegra PMC has clk_out_1, clk_out_2, and clk_out_3. PMC also has blink
39 control which allows 32Khz clock output to Tegra blink pad.
41 Consumer of PMC clock should specify the desired clock by having the
42 clock ID in its "clocks" phandle cell with PMC clock provider. See

185 domain on the Tegra SoC that can be power-gated by the Tegra PMC.
187 Hardware blocks belonging to a power domain should contain "power-domains"
191 every powergate is applicable to all Tegra devices and the following list
