2014-11-14usb:ehci-mx6 add phy mode query functionPeng Fan
usb_phy_enable should return status bit, but not phy mode bit, thus add a new function usb_phy_mode to query the PHY for it's mode and make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'. Include a new board weak function board_usb_phy_mode. If board code does not reimplement this function, it just call usb_phy_mode and return usb_phy_mode's return value. The reason to include such a weak function is: " SOC OTG core <--connect--> board HOST port, but no pin id for the board host port, so board can not use usb_phy_mode to return the phy mode, but define it's own rule."

2014-02-06usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driverLukasz Majewski
The Samsung's UDC driver is not anymore copying data from USB requests to aligned internal buffers. Now it works directly in data allocated in the upper layers like UMS, DFU, THOR. This change is possible since those gadgets now must take care to allocate buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE). This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer aligned to cache line in both starting address and its size. Sometimes it is enough to just use memalign() with size being a multiplication of cache line size.

2013-07-29usb: mv_udc: Make use of struct ehci_ctrlMarek Vasut
The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

This patch adds support to both Faraday FUSBH200 and FOTG210, the differences between Faraday EHCI and standard EHCI are listed bellow: 1. The PORTSC starts at 0x30 instead of 0x44. 2. The CONFIGFLAG(0x40) is not only un-implemented, and also has its address space removed. 3. Faraday EHCI is a TDI design, but it doesn't compatible with the general TDI implementation found at both U-Boot and Linux. 4. The ISOC descriptors differ from standard EHCI in several ways. But since U-boot doesn't support ISOC, we don't have to worry about that. Signed-off-by: Kuo-Jung Su <dantesu@faraday-tech.com> CC: Marek Vasut <marex@denx.de>
