7 title: Shared Peripherals Bus Interface
10 - Shawn Guo <shawnguo@kernel.org>
13 A simple bus enabling access to shared peripherals.
15 The "spba-bus" follows the "simple-bus" set of properties, as
16 specified in the Devicetree Specification. It is an extension of
17 "simple-bus" because the SDMA controller uses this compatible flag to
18 determine which peripherals are available to it and the range over which
19 the SDMA can access. There are no special clocks for the bus, because
20 the SDMA controller itself has its interrupt and clock assignments.
32 pattern: "^spba-bus(@[0-9a-f]+)?$"
63 compatible = "fsl,spba-bus", "simple-bus";
66 reg = <0x30000000 0x100000>;
