      i2c: soft: Fix typo in CONFIG_SYS_I2C_SOFT_SPEED · 90f002a9
      Marek Vasut authored
      In case only the CONFIG_SYS_I2C_SPEED is set in configuration file,
      the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED.
      The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver.
      
      Unfortunatelly, due to a typo in the driver, instead of defining
      CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined
      and therefore the driver failed to compile. The same applies for
      CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well.
      
      This patch fixes the issue.

      ehci-hcd: fix memory leak in lowlevel init · 8bc36036
      Nikita Kiryanov authored
      usb_lowlevel_init() allocates a new periodic_list each time it is invoked,
      without freeing the original list. Since it is initialized later on in the code,
      just reuse the first-allocated list in future invocations of usb_lowlevel_init.

      usb_hub: fix power cycling logic · 0adc331b
      Nikita Kiryanov authored
      When power cycling the hub ports, a misbehaving port will prevent all ports
      from being powered on because we quit at the first sign of trouble.
      
      Skip problematic ports instead of failing the entire power on.

      usb: ehci-omap: Don't softreset USB High-speed Host (UHH) Module · bb1f327d
      Roger Quadros authored
      Fixes NFS root problems with Beagle (3530 ES1.0) when used with
      external USB-ethernet adapter and "USB start" command used within
      u-boot.
      
      Soft resetting the UHH module causes instability issues on
      all OMAPs so we just avoid it.
      
      See OMAP36xx Errata
        i571: USB host EHCI may stall when entering smart-standby mode
        i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock
      
      On OMAP4/5, soft-resetting the UHH module can put it into
      Smart-Idle mode and lead to a deadlock.
      
      On OMAP3 this doesn't seem to be the case but still instabilities
      are observed on beagle (3530 ES1.0) if soft-reset is used.
       e.g. NFS root failures with Linux kernel.

      dfu: Implementation of target reset after communication with dfu-util's -R switch · 6bed7ce5
      Lukasz Majewski authored
      This patch extends dfu code to support transmission with -R switch
      specified at dfu-util.
      
      When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
      successful data transmission. Then dfu resources are released and reset
      command is issued.

      The endpoint QH list has to be aligned to 10-bit boundary. We also have
      to make sure the list is aligned on a cacheline boundary. Make sure it
      is. Furthermore, check if the memory allocation for the QH list didn't
      fail. Moveover, improve the comment about the QH list structure.
      
      Finally, the qTD item list has to be aligned only to 5-bit boundary, not
      10-bit as it is now, fix this as well.

      usb: mv_udc: Make use of struct ehci_ctrl · be7ed253
      Marek Vasut authored
      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.
