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.

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.
