Subject: [PATCH v3 1/2] dt-bindings: power: reset: Unrequire regmap property in syscon-reboot node
Date: Tue, 26 May 2020 16:51:00 +0300 [thread overview]
Message-ID: <20200526135102.21236-2-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20200526135102.21236-1-Sergey.Semin@baikalelectronics.ru>
Since normally syscon-reboot block is supposed to be a part of a system
controller, lets mark the regmap property as deprecated and recommend the
syscon-reboot node to be a sub-node of SYSCON.
