Subject: [PATCH v3 1/3] dt-bindings: mmc: add cap-sdio-async-irq flag
Date: Mon, 17 Jan 2022 15:12:18 +0800	[thread overview]
Message-ID: <20220117071220.17330-2-axe.yang@mediatek.com> (raw)
In-Reply-To: <20220117071220.17330-1-axe.yang@mediatek.com>

Asynchronous interrupt is a mechanism that allow SDIO devices alarm
interrupt when host stop providing clock to card. Add a DT flag to
enable this feature if it is supported by SDIO card.
