* MIPS: Sibyte: Fix locking in set_irq_affinityThomas Bogendoerfer2009-05-142-10/+4
| | | | | | | | Locking of irq_desc is now done in irq_set_affinity; don't lock it again in chip specific set_affinity function. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: Use force_sig when handling address errors.David Daney2009-05-141-3/+3
| | | | | | | | | | | | | | When init is started it is SIGNAL_UNKILLABLE. If it were to get an address error, we would try to send it SIGBUS, but it would be ignored and the faulting instruction restarted. This results in an endless loop. We need to use force_sig() instead so it will actually die and give us some useful information.

| * Input: add driver for S1 button of rb532Phil Sutter2009-03-092-18/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 This procedure works fine and has been tested as part of another, unpublished driver for this device.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>
