The driver PM resume assumes that the IP is still powered up and the all the register contents are not disturbed when it comes out of low power suspend case. This assumption is wrong, basically the driver should not consider any state of registers after it comes out of low power. However driver can keep the part of the IP powered up if its a wake up source. But it can not assume the register state of the IP. Also its possible that SOC glue layer can take the power off the IP if its not wake-up source to reduce the power consumption. This patch re initializes hardware by calling stmmac_hw_setup function in resume case.
