* usb: phy: make PHY driver selection possible by controller driversRoger Quadros2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert PHY Drivers from menuconfig to menu so that the PHY drivers can be explicitely selected by the controller drivers. USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

* USB: EHCI: add delay during suspend to prevent erroneous wakeupsAlan Stern2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | High-speed USB connections revert back to full-speed signalling when the device goes into suspend. This takes several milliseconds, and during that time it's not possible to tell reliably whether the device has been disconnected. On some platforms, the Wake-On-Disconnect circuitry gets confused during this intermediate state. It generates a false wakeup signal, which can prevent the controller from going to sleep. To avoid this problem, this patch adds a 5-ms delay to the ehci_bus_suspend() routine if any ports have to switch over to full-speed signalling. (Actually, the delay was already present for devices using a particular kind of PHY power management; the patch merely causes the delay to be used more widely.)

* usb: chipidea: udc: using MultO at TD as real mult value for ISO-TXPeter Chen2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have met a bug that the high bandwidth ISO-TX transfer has failed at the last packet if it is less than 1024, the TD status shows it is "Transaction Error". The root cause of this problem is: the mult value at qh is not correct for current TD's transfer length. We use TD list to queue un-transfer TDs, and change mult for new adding TDs. If new adding TDs transfer length less than 1024, but the queued un-transfer TDs transfer length is larger than 1024, the transfer error will occur, and vice versa. Usually, this problem occurs at the last packet, and the first packet for new frame. We fixed this problem by setting Mult at QH as the largest value (3), and set MultO (Multiplier Override) at TD according to every transfer length. It can cover both hardware version less than 2.3 (the real mult is MultO if it is not 0) and 2.3+ (the real mult is min(qh.mult, td.multo)). Since the MultO bits are only existed at TX TD, we keep the ISO-RX behavior unchanged. For stable tree: 3.11+.
