[PATCH V3 0/4] PCI: exynos: use the PHY generic framework

From: Jaehoon Chung
Date: Mon Feb 13 2017 - 03:27:28 EST

This patcheset is for using PHY generic framework.
Current pci-exyns doesn't use the phy framework since there haven't been on
PHY subsystem when Exynos5440 had bean upstreamed.
It's making a difficult to upstream the other Exynos variants because of different
PHY registers.

This patcheset has the below modifications:
1) Introduces the phy-exynos-pcie
2) Handles PHY register from PHY framework for pci-exynos
3) Modifies the dt-binding of pci-exynos
4) Maintains the backward compatibility

Changelog on V3:
- Drops "ARM: dts: exynos5440: support the phy-pcie node of pcie"
: Will send this patch after applying this patchset.
- Fixes typo
- Based on latest PCI git repository (host-exynos branch)
- Changes commit message
- Removes the dependency

Changelog on V2:
- Keep current codes for backward compatibility
- Fixes some typos
- Split the patches for removing the dependency
- Removes the unnecessary codes
- Change the patch's sequence
- Based on latest PCI git repository.(next branch)
