looking at mfd driver:

                 * BD71815 data-sheet does not list the power-button IRQ so we
                 * don't use it.
                 */
                button_irq = 0;
....

 if (button_irq) {
                ret = rohm_register_pwrbutton(&i2c->dev, button_irq,
                                              "bd71828-pwrkey", true, irq_domain);
                if (ret)
                        return ret;
        }
....
so you are right about the power button.
Sashiko wants some error-checking there, so I'll send a
v2 with a fixes-tag and error checking.
