[PATCH v2 0/6] Samsung USB PHY SoC support cleanup

[Tomasz Figa]

This patch series intends to improve handling of SoC-specific differences
in Samsung USB PHY drivers, by reducing the need to explicitly check
SoC type using if and switch statements.

In addition, last patch adds support for Exynos 4x12, as this is simply
a matter of adding appropriate driver data and additional case in two switches.

Tested on Exynos4210-based Trats board and Exynos4412-based internal
Samsung board.

Changes since v1:
 - rebased to latest usb-next

  usb: phy: samsung: Consolidate reference clock rate handling
  usb: phy: samsung: Pass set_isolation callback through driver data
  usb: phy: samsung: Pass enable/disable callbacks through driver data
  usb: phy: samsung: Add support for USB 2.0 PHY on Exynos 4x12
