TPS6521905: TPS6521901: simulate any fault in PMIC to trigger the interrupt on nINT pin

Hi,

May i know the reason for simulating PMIC fault?

Register 0x2B shows the interrupt source and the corresponding registers show what kind of faults generates interrupt.

i think, the easy one should be if EN/PB is configured as PB, pushing down PB would generate an interrupt.

PMIC fault generation is part of our manufacturing test sequence.

i think, the easy one should be if EN/PB is configured as PB, pushing down PB would generate an interrupt.

Can you please provide the procedure, and which fault will be logged in this case?

Thanks, Sathish, I have one more question.

We are referring to the BeaglePlay DTS file as a reference for our design, which uses the AM62xx SoC. I have a question regarding the TPS65219 PMIC interrupt configuration.

As per the TPS65219 datasheet, the IRQ line is an open-drain output that is pulled low to indicate a fault or interrupt. However, in the BeaglePlay DTS, the PMIC interrupt is configured as IRQ_TYPE_LEVEL_HIGH instead of IRQ_TYPE_LEVEL_LOW?

tps65219: pmic@30 {    compatible = "ti,tps65219";    reg = <0x30>;    buck1-supply = <&vsys_5v0>;    buck2-supply = <&vsys_5v0>;    buck3-supply = <&vsys_5v0>;    ldo1-supply = <&vdd_3v3>;    ldo2-supply = <&buck2_reg>;    ldo3-supply = <&vdd_3v3>;    ldo4-supply = <&vdd_3v3>;     pinctrl-names = "default";    pinctrl-0 = <&pmic_irq_pins_default>;    interrupt-parent = <&gic500>;    interrupts = <GIC_SPI 224 IRQ_TYPE_LEVEL_HIGH>;    interrupt-controller;    #interrupt-cells = <1>;};

Given the open-drain nature of the IRQ line (active low), why is the DTS configuration using IRQ_TYPE_LEVEL_HIGH instead of IRQ_TYPE_LEVEL_LOW?
