2ppc476gtr High Speed Serial Assist (HSTA) node
3==============================================

5The 476gtr SoC contains a high speed serial assist module attached
6between the plb4 and plb6 system buses to provide high speed data
7transfer between memory and system peripherals as well as support for
8PCI message signalled interrupts.

10Currently only the MSI support is used by Linux using the following
11device tree entries:
12
13Require 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.
