powerpc/fsl_msi: enable msi allocation in all banks

2010-05-25T02:26:32+00:00

Put all fsl_msi banks in a linked list. The list of banks then can be
traversed when allocating new msi interrupts.  Also fix failing path
of fsl_setup_msi_irqs().

powerpc: Convert the FSL MSI code to use msi_bitmap

2008-08-20T06:34:58+00:00

This is 90% straight forward, although we have to change a few
printk format strings as well because of the change in type of hwirq.

powerpc: fsl_msi doesn't need it's own of_node

2008-08-20T06:34:57+00:00

The FSL MSI code keeps a pointer to the of_node from the device
it represents.  However it also has an irq_host, which contains
a pointer to the of_node, so use that one instead.

[POWERPC] fsl: PCIe MSI support for 83xx/85xx/86xx processors.

2008-06-02T19:44:24+00:00

This MSI driver can be used on 83xx/85xx/86xx board.
In this driver, virtual interrupt host and chip were
setup. There are 256 MSI interrupts in this host, Every 32
MSI interrupts cascaded to one IPIC/MPIC interrupt.
The chip was treated as edge sensitive and some necessary
functions were setup for this chip.

Before using the MSI interrupt, PCI/PCIE device need to
ask for a MSI interrupt in the 256 MSI interrupts. A 256bit
bitmap show which MSI interrupt was used, reserve bit in
the bitmap can be used to force the device use some designate
MSI interrupt in the 256 MSI interrupts. Sometimes this is useful
for testing the all the MSI interrupts. The msi-available-ranges
property in the dts file was used for this purpose.
