2013-03-12ARM: w1-gpio: fix erroneous gpio requestsJohan Hovold
Fix regression introduced by commit d2323cf773 ("onewire: w1-gpio: add ext_pullup_enable pin in platform data") which added a gpio entry to the platform data, but did not add the required initialisers to the board files using it. Consequently, the driver would request gpio 0 at probe, which could break other uses of the corresponding pin. On AT91 requesting gpio 0 changes the pin muxing for PIOA0, which, for instance, breaks SPI0 on at91sam9g20.

Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup.

2013-01-23ARM: palmtreo: fix #ifdefs for leds-gpio deviceMike Dunn
The #ifdefs around the leds-gpio device platform data are erroneous. Currently the device is not instantiated on the centro unless CONFIG_MACH_TREO680 is defined. This patch eliminates the #ifdefs, and uses the machine_is_* macros to initialize the data based on which machine the code is running on and the build-time configuration. Unused data is optimized out by the build tools if build configuration does not enable support for both machines. Tested on my palm treo 680, and compile-tested for all three combinations of treo680/centro build configurations.

2013-01-23ARM: palmtreo: fix lcd initilialization on treo680Mike Dunn
This patch gets the LCD working on my Palm Treo680 by adding some code that manages the three gpios interfaced to the lcd on the Treo 680. The precise role of each gpio in the hardware architecture is not entirely clear to me; this patch is the result of trial-and-error and observing how the PalmOS code initializes the lcd. The need for this patch is not evident when Linux is loaded from PalmOS, because at that point the lcd-related gpios have already been configured. But when booting the kernel by other means, this patch is required unless the bootloader has performed the necessary initialializations.

2013-01-08ALSA: pxa27x: fix ac97 warm resetMike Dunn
This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.

2013-01-03ARM: drivers: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
