Hi everyone, This series enables USB host support for the Allwinner A83T SoC. The A83T's USB OTG PHY uses different controls. The USB 2.0 host PHYs are the same as previous chips. And the HSIC part is actually used on some boards. The external bits needed for proper USB OTG support is not there yet, namely the regulators and power supplies for VBUS sensing and control. This will be enabled later on. However the OTG controller is the same as the one found in previous chips. This has been tested under U-boot. Patch 1 adds some properties that were missing for the H3. The H3 has 4 USB host controllers, so there are also 4 USB host PHYs. The properies for the last one were missing. Patch 2 adds a compatible string for the A83T USB PHY block. Patch 3 adds support for a secondary clock for the HSIC PHY. The HSIC block takes a 480MHz clock and a 12MHz clock. All known chips only have at most 1 HSIC capable host/PHY. Patch 4 adds support for the A83T's USB PHYs. The difference is mainly how the OTG PHY (PHY0) is configured. Patch 5 adds the device nodes for the USB PHY and hosts. Patch 6 adds the device node for the USB OTG controller. Patch 7 enables the USB hosts and peripherals on the Cubietruck Plus. Patch 8 enables the USB hosts and peripherals on the H8Homlet v2. The first four patches would go through linux-phy, while I will take the other four through the sunxi tree. For those who want to test this, the series is based on my previous "ARM: sun8i: a83t: Add support for MMC controllers v3" and "mfd: axp20x: Add basic support for AXP813 v2" series.
