Subject: [PATCH v3 2/2] DT: leds: Add an optional property named 'shutdown-gpios'
Date: Tue, 25 Aug 2020 16:22:06 +0800 [thread overview]
Message-ID: <20200825082206.26575-2-von81@163.com> (raw)
In-Reply-To: <20200825082206.26575-1-von81@163.com>
The chip enters hardware shutdown when the SDB pin is pulled low.
The chip releases hardware shutdown when the SDB pin is pulled high.
