* sunxi: musb: Support checking VBUS using AXP221 PMICChen-Yu Tsai2015-03-10-14/+38
| | | | | | | | | | | | | | | | This enables the musb glue layer to use the AXP221's VBUS detection function to check for VBUS. This fixes otg support on the A23 q8h tablets. Note that u-boot never calls musb_shutdown(), so once VBUS is enabled, it is never disabled until the system is powered off, or the OS does so. This can be used to our advantage to keep VBUS powered into the OS, where support for AXP221 is not available yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OUT transactions must be aligned to wMaxPacketSize for each transfer, or else transfer will not complete successfully. This patch modifies rx_bytes_expected to return a transfer length that is aligned to wMaxPacketSize. Note that the value of wMaxPacketSize and ep->maxpacket may not be the same value, and it is the value of wMaxPacketSize that should be used for alignment. wMaxPacketSize is passed depending on the speed of connection.

| * usb: musb-new: omap2430: Reset the MUSB controller earlyPaul Kocialkowski2015-02-24-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting from USB peripheral boot, the bootrom will not properly deinit the MUSB controller, which doesn't clearly indicate an USB disconnection to the host and leaves U-Boot to deal with the state of the previous USB session. On some host controller drivers (e.g. xhci_hcd), this ends up in a failure during set address, caused by the lack of proper disconnection notification. Resetting the controller early in U-Boot notifies the host of the disconnection and doesn't hurt other use cases.

* musb-new: Fix reset sequence when in host modeHans de Goede2015-01-18-11/+20
| | | | | | | | | | | | | | | | | | | | | | This commit fixes a number of issues with the reset sequence of musb-new in host mode: 1) Our usb device probe relies on a second device reset being done after the first descriptors read. Factor the musb reset code into a usb_reset_root_port function (and add this as an empty define for other controllers), and call this when a device has no parent. 2) Just like with normal usb controllers there needs to be a delay after reset, for normal usb controllers, this is handled in hub_port_reset, add a delay to usb_reset_root_port. 3) Sync the musb reset sequence with the upstream kernel, clear all bits of power except bits 4-7, and increase the time reset is asserted to 50 ms. With these fixes an usb keyboard I have now always enumerates properly, where as earlier it would only enumerare properly once every 5 tries. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* musb-new: Fix interrupt transfers not workingHans de Goede2015-01-18-1/+1
| | | | | | | | | | | | | | For bulk and ctrl transfers common/usb.c sets udev->status = USB_ST_NOT_PROC, but it does not do so for interrupt transfers. musb_uboot.c: submit_urb() however was waiting for USB_ST_NOT_PROC to become 0, and thus without anyone setting USB_ST_NOT_PROC would exit immediately for interrupt urbs, returning the urb status of EINPROGRESS as error. This commit fixes this, thereby also making usb_kbd.c work together with musb_new and CONFIG_SYS_USB_EVENT_POLL. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* musb-new: Use time based timeouts rather then cpu-cycles based timeoutsHans de Goede2015-01-18-8/+8
| | | | | | | | | | | | CPU cycle based timeouts are no good, because how long they use depends on CPU speed. Instead use time based timeouts, and wait one second for a device connection to show up (per the USB spec), and wait USB_TIMEOUT_MS for various urbs to complete.
