Subject: [PATCH v2 01/14] mmc: sdhci: do not enable card detect interrupt for gpio cd type
Date: Tue, 3 Dec 2019 12:54:17 +0000 [thread overview]
Message-ID: <20191203130120.11511-2-haibo.chen@nxp.com> (raw)
In-Reply-To: <20191203130120.11511-1-haibo.chen@nxp.com>
Except SDHCI_QUIRK_BROKEN_CARD_DETECTION and MMC_CAP_NONREMOVABLE,
we also do not need to handle controller native card detect interrupt
for gpio cd type.
If we wrong enabled the card detect interrupt for gpio case, it will
cause a lot of unexpected card detect interrupts during data transfer
which should not happen.
