This problem was hidden by power domain driver, which call run time resume before it. But the below commit remove it and make this issue happen. commit c1df456d0f06e ("PM: domains: Don't runtime resume devices at genpd_prepare()") This patch call run time resume before suspend to make sure clock is on before access register.

Este problema fue ocultado por el controlador de dominio de energía, que solicita la reanudación del tiempo de ejecución antes. Pero el siguiente compromiso lo elimina y hace que este problema suceda. commit c1df456d0f06e ("PM: dominios: no reanudar el tiempo de ejecución de los dispositivos en genpd_prepare()") Este parche llama al tiempo de ejecución para reanudar antes de la suspensión para asegurarse de que el reloj esté encendido antes del registro de acceso.
