Subject: [PATCH v5 0/4] usb: ehci/ohci-exynos: Move to generic phy framework

Based and tested on 'usb-next' branch of Greg's usb tree, with relevant
device tree patches[1]

Hi Alan,
 I have included your Acked-by in all the four patches, but there has been
 some amount of restructuring as suggested by Tomasz Figa.
 Please let me know if you have some comments on this patch-series.

Changes from v4:
 - Addressed review comments for restructuring exynos_ohci_get_phy()
   and exynos_ehci_get_phy(); and thereby adding proper checks in
   exynos_ohci_phy_enable()/disable() as well as exynos_ehci_phy_enable()/
   disable().

Changes from v3:
 - Calling usb_phy_shutdown() when exynos_o/ehci_phy_enable() is failing.
 - Made exynos_o/ehci_phy_disable() return void, since its return value
   did not serve any purpose.
 - Calling clk_disable_unprepare() in exynos_o/ehci_resume() when
   exynos_o/ehci_phy_enable() is failed.

Changes from v2:
 - Added two patches in the series for some cleanup.
   usb: ohci-exynos: Use struct device instead of platform_device
   usb: ehci-exynos: Use struct device instead of platform_device
 - Addressed review comments.
   -- Moved exynos_ohci_phyg_on()/off routines inside
      exynos_ohci_phy_enable()/disable.
   -- Added functions exynos_ehci_phy_enable() and exynos_ehci_phy_disable()
      and moved exynos_ehci_phyg_on()/off routines respectively in them.
   -- Added necessary checks.
