Hi Tim: After I changed the wait clocks stabilize delay after pcie_ref_en is set in this patch-set. Can you help to make a double check whether it's ok or not at your side? Thanks in advanced. Main changes since the v1: 1. Regarding to Lucas' comments, seperated the enalbe pcie on imx6qdl sabreauto patch. 2. Add the description why the wait clock stabilize delay should be run after pcie_ref_en is set. 3. Return 0 directly in suspend call back. Main changes since the RFC: Thanks for quick review from Lucas. 1. seperate the smashed patch-set. 2. remove the "power-on-gpio". 3. add/update the pcie-supply of the dts and binding. 4.
