Subject: [PATCH v3 2/6] dt-bindings: gpio: Add DW GPIO debounce clock property
Date: Mon, 23 Mar 2020 22:53:57 +0300 [thread overview]
Message-ID: <20200323195401.30338-3-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200323195401.30338-1-Sergey.Semin@baikalelectronics.ru>
From: Serge Semin <Sergey.Semin@baikalelectronics.ru>
Port A of the DW GPIO controller may optionally have a debounce
logic enabled if it was synthesized with that functionality enabled.
In this case a dedicated reference clock should be declared in the
node with corresponding "db" name presented in the clock-names
property.
