* MIPS: Whitespace cleanup.Ralf Baechle2013-02-0110-64/+64
| | | | | | | | Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: PMC-Sierra Yosemite: Remove support.Ralf Baechle2012-12-131-1/+0
| | | | | | | Nobody seems to be interested anymore and upstream also never had an ethernet driver. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: Hardwire detection of DSP ASE Rev 2 for systems, as required.Ralf Baechle2012-10-111-0/+1
| | | | | | | | Most supported systems currently hardwire cpu_has_dsp to 0, so we also can disable support for cpu_has_dsp2 resulting in a slightly smaller kernel. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* Input: add driver for S1 button of rb532Phil Sutter2009-03-091-0/+3
| | | | | | | | | | | | | | | | | | | Mikrotik's Routerboard 532 has two builtin buttons, from which one triggers a hardware reset. The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* MIPS: RB532: Export rb532_gpio_set_func()Phil Sutter2009-01-301-0/+1
| | | | | | | | | | This kernel symbol provides a way for drivers to switch on alternate function for a certain GPIO pin. Turning it off is done implicitly when changing the GPIO direction, as that would be fixed when using the given pin als alternate function.

* MIPS: RB532: Update headersPhil Sutter2009-01-302-4/+3
| | | | | | | | | Remove the {set,get}_434_reg() prototypes, as the functions have been removed. Also move the prototypes for {get,set}_latch_u5() to the correct place. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: RB532: Add set_type() function to IRQ struct.Phil Sutter2009-01-301-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Interrupt Group 4 mapps the GPIO pins enabled as interrupt sources; add defines to make this clear when addressing them later in code. The mapped GPIOs support triggering on either level high or low. To achieve this, the set_type() function calls rb532_gpio_set_ilevel() for interrupts of the above mentioned group. As there is no way to alter the triggering characteristics of the other interrupts, accept level triggering on status high only. (This is just a guess; but as the system boots fine and interrupt-driven devices (e.g. serial console) work with no implications, it seems to be right.) To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the interrupt status bit of the corresponding GPIO pin). This is done inside rb532_disable_irq(). After applying these changes I could undo most of my former "fixes" to pata-rb532-cf. Particularly all interrupt handling can be done generically via set_irq_type() as it was before.

* MIPS: RB532: Provide functions for gpio configurationPhil Sutter2008-11-201-0/+2
| | | | | | | | | | As gpiolib doesn't support pin multiplexing, it provides no way to access the GPIOFUNC register. Also there is no support for setting interrupt status and level. These functions provide access to them and are needed by the CompactFlash driver. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: RB532: GPIO register offsets are relative to GPIOBASEFlorian Fainelli2008-11-201-6/+8
| | | | | | | | | | | | | This patch fixes the wrong use of GPIO register offsets in devices.c. To avoid further problems, use gpio_get_value to return the NAND status instead of our own expanded code. Also define the zero offset of the alternate function register to allow consistent access.

* MIPS: RB532: provide GPIO_BUILTIN_NR and irq_to_gpio/gpio_to_irqFlorian Fainelli2008-10-111-7/+7
| | | | | | | | | | | This patchs defines the number of built-in the GPIOs present on the SoC as Documentation/gpio.txt recommends to do. Define irq_to_gpio/gpio_to_irq to return the right values so that it fixes a compilation error on drivers/gpio/gpiolib.c when enabling debugfs.
