ppc476gtr High Speed Serial Assist (HSTA) node
|
|
==============================================
|
|
|
|
The 476gtr SoC contains a high speed serial assist module attached
|
|
between the plb4 and plb6 system buses to provide high speed data
|
|
transfer between memory and system peripherals as well as support for
|
|
PCI message signalled interrupts.
|
|
|
|
Currently only the MSI support is used by Linux using the following
|
|
device tree entries:
|
|
|
|
Require properties:
|
|
- compatible : "ibm,476gtr-hsta-msi", "ibm,hsta-msi"
|
|
- reg : register mapping for the HSTA MSI space
|
|
- interrupts : ordered interrupt mapping for each MSI in the register
|
|
space. The first interrupt should be associated with a
|
|
register offset of 0x00, the second to 0x10, etc.
