Subject: [PATCH v1 1/3] dt-bindings: mmc: add cap-sdio-async-int flag
Date: Mon, 27 Dec 2021 16:36:39 +0800 [thread overview]
Message-ID: <20211227083641.12538-2-axe.yang@mediatek.com> (raw)
In-Reply-To: <20211227083641.12538-1-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.
