From: Tony Lindgren <tony@atomide.com> To: linus.walleij@linaro.org Cc: linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org Subject: [PATCH 0/4] pinctrl single support for SoC specific features Date: Fri, 07 Jun 2013 13:50:32 -0700 [thread overview] Message-ID: <20130607203936.16513.57494.stgit@localhost> (raw) Hi all, Here are few patches to add support for SoC specific features to pinctrl-single. This is needed at least for omaps to support IO chain wake-up events from deeper idle states. With this patch series, device drivers can request named pinctrl states like active and idle from the PM runtime suspend and resume calls to set the wake enable bits for selected pins. Further the device driver can toggle the wake-up feature as needed based on the device_may_wakeup() state set by the standard sysfs power/wakeup entry. This is implemented in a separate pinctrl-single-omap driver that works together with pinctrl-single. This way the SoC specific are separated from the common pinctrl-single, and allows a relatively easy way to implement SoC specific things like wake-up events, pin interrupts, and GPIO.
