Required properties:
|
|
- compatible: should be "amlogic,meson-gxbb-efuse"
|
|
- clocks: phandle to the efuse peripheral clock provided by the
|
|
clock controller.
|
|
- secure-monitor: phandle to the secure-monitor node
|
|
|
|
= Data cells =
|
|
Are child nodes of eFuse, bindings of which as described in
|
|
bindings/nvmem/nvmem.txt
|
|
|
|
Example:
|
|
|
|
efuse: efuse {
|
|
compatible = "amlogic,meson-gxbb-efuse";
|
|
clocks = <&clkc CLKID_EFUSE>;

reg = <0x14 0x10>;
|
|
};

eth_mac: eth_mac@34 {
|
|
reg = <0x34 0x10>;
|
|
};

bid: bid@46 {

reg = <0x46 0x30>;

};

sm: secure-monitor {

compatible = "amlogic,meson-gxbb-sm";

= Data consumers =
|
|
Are device nodes which consume nvmem data cells.
|
|
|
|
For example:
|
|
|
|
eth_mac {
|
|
...
|
|
nvmem-cells = <ð_mac>;
|
|
nvmem-cell-names = "eth_mac";
|
|
};
