* ARM: pxa: Initialize PWM backlight enable_gpio fieldThierry Reding2013-10-161-0/+1
| | | | | | | | | | | The GPIO API defines 0 as being a valid GPIO number, so this field needs to be initialized explicitly. A special case is the Palm Tungsten|C board. Since it doesn't use any quirks that would require the existing .init() or .exit() hooks it can simply use the new enable_gpio field. Signed-off-by: Thierry Reding <treding@nvidia.com>
* ARM: w1-gpio: fix erroneous gpio requestsJohan Hovold2013-03-121-0/+1
| | | | | | | | | | | | | | | | 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.

* ARM: delete struct sys_timerStephen Warren2012-12-241-3/+3
| | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* Input: eeti_ts: pass gpio value instead of IRQArnd Bergmann2012-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EETI touchscreen asserts its IRQ line as soon as it has data in its internal buffers. The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ. Without this patch, building raumfeld_defconfig results in: drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active': drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org (v3.2+) Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Sven Neumann <s.neumann@raumfeld.com> Cc: linux-input@vger.kernel.org Cc: Haojian Zhuang <haojian.zhuang@gmail.com>
