NVIDIA Tegra18x Bridge MCA driver
|
||
|
|
==================================
|
||
|
|
|
||
|
|
This document defines the device-specific binding for the Tegra18x bridge MCA driver.
|
||
|
|
The Bridge MCA driver adds support for AXI/APB bridge machine check hardware in T18x.
|
||
|
|
The driver reports relevant information like CPU, bus address, error status, type of bridge, etc in case of a Bridge MCA.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible: Should be "nvidia,tegra186-AXI2APB-bridgei"
|
||
|
|
- reg: Physical base address and length of registers
|
||
|
|
- clocks: Specifies the needed clocks
|
||
|
|
- clock-names: Specifies the names of the needed clocks
|
||
|
|
- timeout: specify the bridge timeout in micro seconds (us)
|
||
|
|
|
||
|
|
Below is a sample bridge DT entry for configuring bridge timeout=500 usec
|
||
|
|
for axi2apb@2390000 bridge.
|
||
|
|
|
||
|
|
axi2apb@2390000 {
|
||
|
|
compatible = "nvidia,tegra186-AXI2APB-bridge";
|
||
|
|
reg = <0x0 0x02390000 0x0 0x1000>;
|
||
|
|
clocks = <&tegra_car TEGRA186_CLK_AXI_CBB>;
|
||
|
|
clock-names = "axi_cbb";
|
||
|
|
timeout = <500>;
|
||
|
|
status = "disabled";
|
||
|
|
};
