Subject: [PATCH v2 1/9] mmc: core: Add DT bindings for eMMC hardware reset support
Date: Tue, 20 Oct 2015 17:13:03 +0800 [thread overview]
Message-ID: <1445332391-30530-2-git-send-email-chaotian.jing@mediatek.com> (raw)
In-Reply-To: <1445332391-30530-1-git-send-email-chaotian.jing@mediatek.com>
Sometime only need set MMC_CAP_HW_RESET for one of MMC hosts,
So set it in device tree is better.
