Subject: [PATCH v3 01/14] mmc: sdhci: do not enable card detect interrupt for gpio cd type
Date: Mon, 10 Feb 2020 16:56:16 +0800	[thread overview]
Message-ID: <1581324979-31084-2-git-send-email-haibo.chen@nxp.com> (raw)
In-Reply-To: <1581324979-31084-1-git-send-email-haibo.chen@nxp.com>

From: Haibo Chen <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.
