I will use the 'ep' as name, exynos_pcie is a little bit long. When 'exynos_pcie' is used, some code is need to change lines because of 80 char. I think it's the meaningless line changing. I will resend the PATCH v2..also patches relevant to using PHY framework. After applying everything, i will upstream TM2(Exynos5433) PCIe patches. Thanks for reviewing.
