Piyush Mehta e144fc9ccc phy: xilinx: phy-zynqmp: Fix SGMII linkup failure on resume ... [ Upstream commit 5af9b304bc ] On a few Kria KR260 Robotics Starter Kit the PS-GEM SGMII linkup is not happening after the resume. This is because serdes registers are reset when FPD is off (in suspend state) and needs to be reprogrammed in the resume path with the same default initialization as done in the first stage bootloader psu_init routine. To address the failure introduce a set of serdes registers to be saved in the suspend path and then restore it on resume.
