Actualmente, la funci\u00f3n de desinfecci\u00f3n de endpoints dw_pcie_ep_cleanup() y la funci\u00f3n de notificaci\u00f3n deinit de EPF pci_epc_deinit_notify() se llaman durante la ejecuci\u00f3n de pex_ep_event_pex_rst_assert(), es decir , cuando el anfitri\u00f3n tiene afirm\u00f3 PREST#. Pero poco despu\u00e9s de este paso, el host tambi\u00e9n desactivar\u00e1 refclk. Todos los SoC de endpoint tegra194 admitidos a partir de ahora dependen de la refclk del host para mantener el controlador operativo. Debido a esta limitaci\u00f3n, cualquier acceso a los registros de hardware en ausencia de refclk resultar\u00e1 en una falla completa del endpoint. Desafortunadamente, la mayor\u00eda de las desinfecciones del controlador requieren acceder a los registros de hardware (como la desinfecci\u00f3n eDMA realizada en dw_pcie_ep_cleanup(), etc...). Por lo tanto, estas funciones de desinfecci\u00f3n pueden provocar el bloqueo del SoC del endpoint una vez que el host afirma el n\u00famero PREST. Una forma de abordar este problema es generando el refclk en el propio endpoint y sin depender del host. Pero eso no siempre es posible ya que algunos de los dise\u00f1os de terminales requieren que el terminal consuma refclk del host. Por lo tanto, solucione este bloqueo moviendo las desinfecciones del controlador al inicio de la funci\u00f3n pex_ep_event_pex_rst_deassert(). Esta funci\u00f3n se llama siempre que el host ha anulado PERST# y se garantiza que refclk estar\u00e1 activo en este punto.
