Axel Lin bd4abc2f96 phy: samsung-usb2: Remove NULL terminating entry from phys array
Current code uses num_phys settings to tell the number of entries in phys.
Thus remove the NULL terminating entry from phys array which is not necessary.

Marek Szyprowski 016e0d3cb7 drivers: phy: exynos-usb2: add support for Exynos 3250
This patch adds support for Exynos3250 SoC to Exynos2USB PHY driver.
Although Exynos3250 has only one device phy interface, the register
layout and all operations that are required to get it enabled are almost
same as on Exynos4x12. The only different is one more register
(REFCLKSEL) which need to be set and lack of MODE SWITCH register.

Kamil Debski 57416c23e3 phy: phy-samsung-usb2: Change phy power on/power off sequence
The Exynos4412 USB 2.0 PHY hardware differs from the description provided
in the documentation. Some register bits have different function. This
patch fixes the defines of register bits and changes the way how phys are
powered on and off.
