- 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
- - interrupt-parent : parent controller for mapping interrupts
- - 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.
