The watchdog IP block on Meson8 and Meson8m2 is already supported by the existing meson-wdt driver. Meson8 uses the same register bits as Meson6, while the newer Meson8m2 SoC uses the same register bits as Meson8b. Currently watchdog support on Meson8 SoC already works because meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a separate compatible for Meson8 makes this more explicit though.

Meson SoCs Watchdog timer
|
|
|
|
Required properties:
|
|
|
|
- compatible : depending on the SoC this should be one of:
|
|
"amlogic,meson6-wdt" on Meson6 SoCs
|
|
"amlogic,meson8-wdt" and "amlogic,meson6-wdt" on Meson8 SoCs
|
|
"amlogic,meson8b-wdt" on Meson8b SoCs
|
|
"amlogic,meson8m2-wdt" and "amlogic,meson8b-wdt" on Meson8m2 SoCs
|
|
- reg : Specifies base physical address and size of the registers.
|
|
|
|
Example:
|
|
|
|
wdt: watchdog@c1109900 {
|
|
compatible = "amlogic,meson6-wdt";
|
|
reg = <0xc1109900 0x8>;
|
|
};
