4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kishon Vijay Abraham I <kishon@xxxxxx> [ Upstream commit 2c949ce38f4e81d7487f165fa3b8f77d74a2a6c4 ] The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC mode. However in EP mode, the host system is not able to access the MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.
