Subject: [PATCH v2 01/10] dt-bindings: gpio: dwapb: Add ngpios property support
Date: Thu, 30 Jul 2020 16:55:27 +0300
Message-ID: <20200730135536.19747-2-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200730135536.19747-1-Sergey.Semin@baikalelectronics.ru>

It's redundant to have a vendor-specific property describing a number of
GPIOS while there is a generic one. Let's mark the former one as
deprecated and define the "ngpios" property supported with constraints
of being within [1; 32] range.
