[PATCH] PCI: qcom: Ensure that PERST is asserted for at least 100 ms

2019-05-23 Thread Niklas Cassel
Currently, there is only a 1 ms sleep after asserting PERST. Reading the datasheets for different endpoints, some require PERST to be asserted for 10 ms in order for the endpoint to perform a reset, others require it to be asserted for 50 ms. Several SoCs using this driver uses PCIe Mini Card,
