* phy: samsung-usb2: Remove NULL terminating entry from phys arrayAxel Lin2015-03-121-1/+0
| | | | | | | | 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. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
* drivers: phy: exynos-usb2: add support for Exynos 3250Marek Szyprowski2014-07-221-2/+15
| | | | | | | | | | | | 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.
