Subject: [PATCH v6 07/19] dt-bindings: soc: tegra-pmc: Add id for Tegra PMC 32KHz blink clock
Date: Mon, 6 Jan 2020 20:14:06 -0800 [thread overview]
Message-ID: <1578370458-3686-8-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1578370458-3686-1-git-send-email-skomatineni@nvidia.com>
Tegra PMC has blink functionality that allows 32KHz clock out to
blink pin of the Tegra.
This patch adds id for this blink clock to use for enabling or
disabling blink output through device tree.

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