Subject: [PATCH v8 09/22] dt-bindings: soc: tegra-pmc: Add id for Tegra PMC 32KHz blink clock
Date: Mon, 13 Jan 2020 23:24:14 -0800
Message-ID: <1578986667-16041-10-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1578986667-16041-1-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.
