2014-05-30MIPS: Malta: Let PIIX4 respond to PCI special cyclesPaul Burton1-0/+6
This patch enables the PIIX4 to respond to special cycles on the PCI bus. One such special cycle must be used in order to enter a suspend state, and if response to it is not enabled then the suspend state will never be entered.

2014-03-31MIPS: Malta: Setup PM I/O region on bootPaul Burton1-0/+13
This patch ensures that the kernel sets a sane base address for the PIIX4 PM I/O register region during boot. Without this the kernel may not successfully claim the region as a resource if the bootloader didn't configure the region. With this patch the kernel will always succeed with: pci 0000:00:0a.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI The lack of the resource claiming is easily reproducible without this patch using current versions of QEMU.

2014-01-23MIPS: Malta: mux & enable SERIRQ interruptPaul Burton1-0/+11
This patch causes the kernel to mux the SERIRQ interrupt to the SERIRQ pin of the PIIX4 and to enable that interrupt. The kernel depends upon the interrupt when using the SuperIO UARTs (ttyS0 & ttyS1) but previously would not configure it, instead relying upon the bootloader having done so. If that is not the case then the typical result is that the system appears to hang once it reaches userland as no output is displayed on the UART.

2013-01-03MIPS: drivers: remove __dev* attributes.Greg Kroah-Hartman1-5/+5
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.

2012-07-19MIPS: PCI: Move fixups from __init to __devinit.Sebastian Andrzej Siewior1-3/+3
Fixups are executed once the pci-device is found which is during boot process so __init seems fine as long as the platform does not support hotplug. However it is possible to remove the PCI bus at run time and have it rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call the fixups again.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
