Tegra ADMA AST (ADAST) bindings
-------------------------------
The ADMA AST (ADAST) maps local ADMA addresses to physical
addresses. It can also control properties for those regions.
Required properties:
- None
Optional properties:
- nvidia,adast: should specify ADAST regions with a tuple of u64 values:
<region_number, region_control, slave_base, mask, master_base>.
ADMA can specify zero or more AST regions. As 2 out of 8 regions (0 & 1) of
AST are used by boot-loader, only 6 regions can be specified here.
Examples:
1) nvidia,adast = <0x0 0x3 0x0 0x00008008 0x0 0x40000000 0x0 0x20000000 0x0 0x40000000>;
2) nvidia,adast = <0x0 0x3 0x0 0x00008008 0x0 0x40000000 0x0 0x20000000 0x0 0x40000000>,
<0x0 0x4 0x0 0x00008008 0x0 0x60000000 0x0 0x10000000 0x0 0x60000000>;
