2011-11-03powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO driverFelix Radensky
Interrupt handler in MPC8xxx GPIO driver is missing the call to PIC EOI (end of interrupt) handler. As a result, at least on 85XX systems, GPIO interrupt is delivered only once. This patch adds the missing EOI call. Tested on custom P1022 board. Signed-off-by: Felix Radensky <felix@embedded-sol.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-11-03powerpc/85xx: Add 'fsl,pq3-gpio' compatiable for GPIO driverKumar Gala
Support MPC85xx platforms outside of MPC8572/MPC8536. The MPC8572/MPC8536 have an erratum that is worked around based on having "fsl,mpc8572-gpio" in the compatiable list. All other MPC85xx SoCs don't require this workaround and thus utilize the 'fsl,pq3-gpio' compatiable. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2011-10-26gpio: pl061: add DT binding supportRob Herring
This adds devicetree binding support to the ARM pl061 driver removing the platform_data dependency. When DT binding is used, the gpio numbering is assigned dynamically. For now, interrupts are not supported with DT until irqdomains learn dynamic irq assignment. Rather than add another case of -1, updating the driver to use NO_IRQ.

2011-10-24mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann
We currently have two symbols to control compilation the MFD subsystem, MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.

This resulted in the driver compilation broken for certain OMAP1, i.e., non-OMAP16xx, configurations.

2011-10-04gpio/samsung: correct pin configuration for S5PC100/S5PC110/EXYNOS4Marek Szyprowski
Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver use wrong configuration setup for all gpio pins on S5PC100 and S5PV210 SoCs and external interrupt lines on Exynos4 SoCs. This patch fixes this issue.

2011-10-04gpio/samsung: fix GPIO interrupt registration for EXYNOS4 SoCsMarek Szyprowski
Commit 1b39d5f2cc introduced new common gpio driver for all Samsung GPIO SoCs. The new driver doesn't correctly register GPIO interrupts on Samsung Exynos4 SoCs. This is caused by a typo in define name. This patch fixes this issue.
