Subject: [RFC 06/25] dt-bindings: leds: Add Titan Micro Electronics TM1628
Date: Thu, 12 Dec 2019 04:39:33 +0100	[thread overview]
Message-ID: <20191212033952.5967-7-afaerber@suse.de> (raw)
In-Reply-To: <20191212033952.5967-1-afaerber@suse.de>

Add a YAML schema binding for TM1628 LED controller.

Cc: zypeng@titanmec.com
Signed-off-by: Andreas Färber <afaerber@suse.de>

 @Rob: How could we express constraints on two-cell reg value ranges here?
       Should we also model constraints on reg range by #grids property?
