Message-ID: <1455098283-14500-1-git-send-email-ludovic.desroches@atmel.com> Date: Wed, 10 Feb 2016 10:58:03 +0100 From: Ludovic Desroches <ludovic.desroches@...el.com> To: <ulf.hansson@...aro.org> CC: <linux-mmc@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <nicolas.ferre@...el.com>, Ludovic Desroches <ludovic.desroches@...el.com> Subject: [RFC PATCH] mmc: sdhci-of-at91: don't put device in suspend after probe By putting the device in suspend at the end of the probe, it is impossible to wake up on non software event such as card insertion/removal. Signed-off-by: Ludovic Desroches <ludovic.desroches@...el.com> --- Hi, Since I had no feedback on this topic: http://permalink.gmane.org/gmane.linux.kernel.mmc/35160 I would like to no more put the device in suspend at the end of the probe. If my device is suspended at the end of the probe, I have no issue to resume on a software event such as mounting my sdcard but hardware event such as card insertion and removal do not trigger a resume. It seems there are only two sdhci drivers using runtime pm so maybe nobody has noticed this issue.
