There are a total of 6 patches on top of v3.10-rc3. 3 of them (a, b, d) are queued for 3.10-rc4 and another patch (c) is just a defconfig hack to get Arndale booting. Remaining 2 patches (e, f) are required to reset the hub during EHCI initialization. a. ARM: exynos: defconfig update b. ARM: EXYNOS: Update defconfig for Arndale and Origen board c. [TEMP] ARM: EXYNOS: Set low-level UART port to 2 d. ARM: dts: Enabling samsung-usb2phy driver for exynos5250 e. usb: ehci-s5p: add the HSIC port initialization f. ARM: dts: Add USB gpio entries for Arndale board I am not sure whether such kind of board-specific patches (e, f) are appreciated in the drivers. But that is all we need to get USB and Ethernet to work on v3.10-rc3 kernel.
