Date: Mon, 6 Jul 2015 15:16:20 +0300 From: "Ivan T. Ivanov" <ivan.ivanov@...aro.org> To: Ulf Hansson <ulf.hansson@...aro.org> Cc: Adrian Hunter <adrian.hunter@...el.com>, Tim Kryger <tim.kryger@...il.com>, Aisheng Dong <b29396@...escale.com>, linux-mmc@...r.kernel.org, linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org Subject: [PATCH v2 2/3] mmc: sdhci: don't use card state polling when CD GPIO is defined There is no reason to use polling for card detection state change when drivers are using dedicated GPIO for this. Don't poll in this case. Signed-off-by: Ivan T.
