1 2 ppc476gtr High Speed Serial Assist (HSTA) node 3 ============================================== 4 5 The 476gtr SoC contains a high speed serial assist module attached 6 between the plb4 and plb6 system buses to provide high speed data 7 transfer between memory and system peripherals as well as support for 8 PCI message signalled interrupts. 9 10 Currently only the MSI support is used by Linux using the following 11 device tree entries: 12 13 Require properties: 14 - compatible : "ibm,476gtr-hsta-msi", "ibm,hsta-msi" 15 - reg : register mapping for the HSTA MSI space 16 - interrupts : ordered interrupt mapping for each MSI in the register 17 space. The first interrupt should be associated with a 18 register offset of 0x00, the second to 0x10, etc.
