Subject: [PATCH 1/5] dt-bindings: gpio: Binding for MStar MSC313 GPIO controller
Date: Sun, 11 Oct 2020 11:48:27 +0900	[thread overview]
Message-ID: <20201011024831.3868571-2-daniel@0x0f.com> (raw)
In-Reply-To: <20201011024831.3868571-1-daniel@0x0f.com>

Add a binding description for the MStar/SigmaStar GPIO controller
found in the MSC313 and later ARMv7 SoCs.
