| 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. |
