Marek Vasut	a754aea25e	ARM: pxa: fix pxa3xx-u2d crash when ULPI not used ... In case the pxa3xx-u2d driver isn't used, probing of ohci-pxa27x will cause an ugly kernel crash (NULL pointer dereference in pxa3xx_u2d_start_hc(), because struct u2d is NULL and clk_enable() call will crash the kernel, trying to access it).

Igor Grinberg	69f22be7b1	ARM: pxa: add U2D controller and ULPI driver for pxa3xx ... USB2.0 Device Controller (U2DC) which is found in Marvell PXA3xx. U2DC supports both High and Full speed modes. PXA320 and PXA300 U2DC supports only UTMI interface. PXA310 U2DC supports only ULPI interface and has the OTG capability. U2D Controller ULPI driver introduced in this patch supports only the PXA310 USB Host via the ULPI.
