Subject: [PATCH 2/2] dt-bindings: leds: Document mmc trigger
Date: Sun, 24 Oct 2021 02:23:58 +0200	[thread overview]
Message-ID: <20211024002358.225750-2-marex@denx.de> (raw)
In-Reply-To: <20211024002358.225750-1-marex@denx.de>

The mmc subsystem supports triggering leds on card activity, document
the trigger value here. The value is a pattern in this case.
