Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2012-05-30T01:27:19Z

Pull MIPS updates from Ralf Baechle: "The whole series has been sitting in -next for quite a while with no complaints. The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code." Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where printk spelling fixes clashed with file move and eventual removal of the printk. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (81 commits) MIPS: lantiq: remove orphaned code MIPS: Remove all -Wall and almost all -Werror usage from arch/mips.

Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6

2012-05-24T21:01:46Z

Pull GPIO driver changes from Grant Likely: "Lots of gpio changes, both to core code and drivers. Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

GPIO: MIPS: lantiq: convert gpio-stp-xway to OF

2012-05-21T13:31:53Z

Implements OF support and add code to load custom properties from the DT. The Serial To Parallel (STP) is found on MIPS based Lantiq socs. It is a peripheral controller used to drive external shift register cascades. At most 3 groups of 8 bits can be driven. The hardware is able to allow the DSL modem to drive the 2 LSBs of the cascade automatically. Newer socs are also able to automatically drive some pins via the internal PHYs. The driver currently only supports output functionality. Patches for the input feature found on newer generations of the soc will be provided in a later series.

GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpio

2012-05-21T13:31:53Z

Implements OF support and convert to of_mm_gpio. By attaching hardware latches to the External Bus Unit (EBU) on Lantiq SoC, it is possible to create output only gpios. This driver configures a special memory address, which when written to, outputs 16 bit to the latches.

gpio/lpc32xx: Add device tree support

2012-05-18T22:48:36Z

This patch adds device tree support for gpio-lpc32xx.c. To register the various GPIO banks as (struct) gpio_chips via the same DT gpio-controller, we utilize the adjusted of_xlate API to manipulate the actually used struct gpio_chip.
