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. - -Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> -Acked-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> -Signed-off-by: David S.
