2012-11-16gpio-timberdale: fix a potential wrapping issueDan Carpenter
commit d79550a7bc35c16476ebdc27c78378d8093390ec upstream. ->last_ier is an unsigned long but the high bits can't be used int the original code because the shift wraps.

2012-10-10gpio-lpc32xx: Fix value handling of gpio_direction_output()Roland Stigge
commit b1268d3737c6316016026245eef276eda6b0a621 upstream. For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument (initial value of output). This patch fixes this by setting the level accordingly.

2012-07-25gpiolib: wm8994: Pay attention to the value set when enabling as outputMark Brown
commit 8cd578b6e28693f357867a77598a88ef3deb6b39 upstream. Not paying attention to the value being set is a bad thing because it means that we'll not set the hardware up to reflect what was requested. Not setting the hardware up to reflect what was requested means that the caller won't get the results they wanted.

2012-05-31gpio: mpc8xxx: Prevent NULL pointer deref in demux handlerThomas Gleixner
commit d6de85e85edcc38c9edcde45a0a568818fcddc13 upstream. commit cfadd838(powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO driver) added an unconditional call of chip->irq_eoi() to the demux handler. This leads to a NULL pointer derefernce on MPC512x platforms which use this driver as well. Make it conditional.

2012-04-02gpio/davinci: fix enabling unbanked GPIO IRQsSekhar Nori
commit 81b279d80a63628e580c71a31d30a8c3b3047ad4 upstream. Unbanked GPIO IRQ handling code made a copy of just the irq_chip structure for GPIO IRQ lines which caused problems after the generic IRQ chip conversion because there was no valid irq_chip_type structure with the right "regs" populated. irq_gc_mask_set_bit() was therefore accessing random addresses. Fix it by making a copy of irq_chip_type structure instead. This will ensure sane register offsets.

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.

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. Really required or not in previously excluded cases, define this structure member unconditionally as a fix. Tested with a custom OMAP1510 only configuration.
