Pull ARM SoC fixes from from Olof Johansson: "A collection of fixes for ARM platforms. A little large due to us missing to do one last week, but there's nothing in particular here that is in itself large and scary. Mostly a handful of smaller fixes all over the place. The majority is made up of fixes for OMAP, but there are a few for others as well. In particular, there was a decision to rename a binding for the Broadcom pinctrl block that we need to go in before the final release since we then treat it as ABI" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: omap3-gta04: Add ti,omap36xx to compatible property to avoid problems with booting ARM: tegra: add LED options back into tegra_defconfig ARM: dts: omap3-igep: fix boot fail due wrong compatible match ARM: OMAP3: Fix pinctrl interrupts for core2 pinctrl: Rename Broadcom Capri pinctrl binding pinctrl: refer to updated dt binding string.

pinctrl: sunxi: use chained_irq_{enter, exit} for GIC compatibility

2014-03-05T01:57:10Z

On tha Allwinner A20 SoC, the external interrupts on the pin controller device are connected to the GIC. Without chained_irq_{enter, exit}, external GPIO interrupts, such as used by mmc core card detect, cause the system to hang. This issue was first encountered during my attempt to get out-of-band interrupts for WiFi on the Cubietruck working. With David's new series of sunci-mci using mmc slot-gpio for (GPIO interrupt based) card detection, removing the SD card also causes my Cubietruck to hang. This problem should extend to all Allwinner A20 based boards. With this fix, the system no longer hangs when I remove or insert the SD card. /proc/interrupts show that the interrupt has correctly fired. However the system still does not detect card removal/insertion. I believe this is another unrelated issue.

pinctrl: do not init debugfs entries for unimplemented functionalities

2014-02-06T12:48:17Z

Commit c420619 "pinctrl: pinconf: remove checks on ops->pin_config_get" removed the check on (ops != NULL) when performing pinconf_pins_show() or pinconf_groups_show(). As these entries are always enabled, even if pinconf is not supported, reading will result in an oops due to NULL ops. Instead of checking for ops, remove the corresponding debugfs entries if pinconf and/or pinmux are not implemented. Tested on OMAP3 (pinctrl-single).
