Date: Tue, 4 Feb 2014 16:58:56 +0100 From: Ulf Hansson <ulf.hansson@...aro.org> To: Russell King <linux@....linux.org.uk>, linux-arm-kernel@...ts.infradead.org Cc: Alessandro Rubini <rubini@...pv.it>, Linus Walleij <linus.walleij@...aro.org>, Wolfram Sang <wsa@...-dreams.de>, Chris Ball <chris@...ntf.net>, Mark Brown <broonie@...nel.org>, linux-kernel@...r.kernel.org, linux-i2c@...r.kernel.org, linux-spi@...r.kernel.org, linux-mmc@...r.kernel.org, Ulf Hansson <ulf.hansson@...aro.org> Subject: [PATCH 15/17] i2c: nomadik: Convert to late and early system PM callbacks At system suspend_late, runtime PM has been disabled by the PM core which means we can safely operate on these resources. Consequentially we no longer have to wait until the noirq phase of the system suspend.
