Subject: [PATCH v2 2/2] sdhci: tegra: Enable MMC_CAP_WAIT_WHILE_BUSY host capability
Date: Wed, 11 Mar 2020 08:47:55 -0700 [thread overview]
Message-ID: <1583941675-9884-2-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1583941675-9884-1-git-send-email-skomatineni@nvidia.com>
Tegra sdhci host supports HW busy detection of the device busy
signaling over data0 lane.
