* MIPS: Octeon: Use device tree to register serial ports.David Daney2012-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | Switch to using the device tree to register serial ports. Add all the ports with compatible = "cavium,octeon-3860-uart". Octeon serial ports have their own device type, required port flags, and I/O functions, so using of_serial.c is not indicated. We need to do this as late_initcall, as the 8250 driver must be initialized before we add any ports. 8250 initialization is done at device_initcall time. The OCTEON_IRQ_UART{0,1,2} symbols are removed as they are now unused and interfere with irq_domain used by the device tree code.

* netdev: octeon_mgmt: Convert to use device tree.David Daney2012-07-23
| | | | | | | | | | | | | | | | | | | | The device tree will supply the register bank base addresses, make register addressing relative to those. PHY connection is now described by the device tree. The OCTEON_IRQ_MII{0,1} symbols are also removed as they are now unused and interfere with the irq_domain used for device tree irq mapping.

* i2c: Convert i2c-octeon.c to use device tree.David Daney2012-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | There are three parts to this: 1) Remove the definitions of OCTEON_IRQ_TWSI and OCTEON_IRQ_TWSI2. The interrupts are specified by the device tree and these hard coded irq numbers block the used of the irq lines by the irq_domain code. 2) Remove platform device setup code from octeon-platform.c, it is now unused. 3) Convert i2c-octeon.c to use device tree. Part of this includes using the devm_* functions instead of the raw counterparts, thus simplifying error handling. No functionality is changed.

* MIPS: Octeon: Add device tree source files.David Daney2012-07-23
| | | | | | | | | | | | | | | | | | | | | | | | The two device tree files octeon_3xxx.dts and octeon_68xx.dts are trimmed by code in a subsequent patch to reflect the hardware actually present on the board. To this end several properties that are not part of the declared bindings are added to aid in trimming off unwanted nodes. Since the device tree and the code that trims it are bound into the kernel binary, these 'marker' properties never escape into the wild, and are purely an implementation detail of the kernel early boot process. This is done for backwards compatibility with existing boards (identified by a board type enumeration value by their bootloaders). New boards will always pass a device tree from the bootloader, the built-in trees are ignored in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * MIPS: Netlogic: MSI enable fix for XLSGanesan Ramalingam2012-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSI interrupts do not work on XLS after commit a776c49 ( "PCI: msi: Disable msi interrupts when we initialize a pci device" ) because the change disables MSI interrupts on the XLS PCIe bridges during the PCI enumeration. Fix this by enabling MSI interrupts on the bridge in the arch_setup_msi_irq() function. A new function xls_get_pcie_link() has been introduced to get the PCI device corresponding to the top level PCIe bridge on which MSI has to be enabled. Also, update get_irq_vector() to use the new xls_get_pcie_link() function and PCI_SLOT() macro for determining the IRQ of PCI devices.
