Is this some kind of difference between the DW PCIe core revisions? This patch does not alter the LTSSM masks that are used currently and they match the ones stated in the SoC manuals. For keystone: http://www.ti.com/lit/ug/sprugs6d/sprugs6d.pdf Section "48.9.11 Debug Register 0 (PCIE_PL_DEBUG0)" shows that LTSSM current state has 6 bits. For i.MX6: Section "3.9.11 Debug 0 Register (DEBUG0)" shows that LTSSM_STATE field has 5 bits.
