2014-11-14usb: dwc2: Update the gadget driver to use common dwc2_hsotg structureDinh Nguyen2-148/+153
Adds the gadget data structure and appropriate data structure pointers to the common dwc2_hsotg data structure. To keep the driver data dereference code looking clean, the gadget variable declares are only available for peripheral and dual-role mode. This is needed so that the dwc2_hsotg data structure can be used by the hcd and gadget drivers. Updates gadget.c to use the dwc2_hsotg data structure and gadget pointers that have been moved into the common dwc2_hsotg structure.

2014-11-12usb: dwc2: add bus suspend/resume for dwc2Kever Yang1-11/+77
Hcd controller needs bus_suspend/resume, dwc2 controller make root hub generate suspend/resume signal with hprt0 register when work in host mode. After the root hub enter suspend, we can make controller enter low power state with PCGCTL register. We also update the lx_state for hsotg state. This patch has tested on rk3288 with suspend/resume.

commit e47d925 (usb: move the OTG state from the USB PHY to the OTG structure) moved the OTG state from struct usb_phy to struct usb_otg. Unfortunately, even though I fixed quite a few build regressions with that patch already, this one was still missing. Note that this driver still has other randconfig build problems which I'll leave for driver author to fix, as that's less trivial.

2014-11-12scsi: don't set tagging state from scsi_adjust_queue_depthChristoph Hellwig1-1/+1
Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

2014-11-12scsi: always assign block layer tags if enabledChristoph Hellwig1-2/+2
Allow a driver to ask for block layer tags by setting .use_blk_tags in the host template, in which case it will always see a valid value in request->tag, similar to the behavior when using blk-mq. This means even SCSI "untagged" commands will now have a tag, which is especially useful when using a host-wide tag map.

2014-11-12scsi: add new scsi-command flag for tagged commandsChristoph Hellwig1-1/+1
Currently scsi piggy backs on the block layer to define the concept of a tagged command. But we want to be able to have block-level host-wide tags assigned even for untagged commands like the initial INQUIRY, so add a new SCSI-level flag for commands that are tagged at the scsi level, so that even commands without that set can have tags assigned to them. Note that this alredy is the case for the blk-mq code path, and this just lets the old path catch up with it. We also set this flag based upon sdev->simple_tags instead of the block queue flag, so that it is entirely independent of the block layer tagging, and thus always correct even if a driver doesn't use block level tagging yet. Also remove the old blk_rq_tagged; it was only used by SCSI drivers, and removing it forces them to look for the proper replacement.

SET_FEATURE request with DEBUG_MODE only worked the first time after module initialisation. Per the USB 2.0 debug device specification, said request is to be treated as if it were a SET_CONFIGURATION request, i.e. endpoint must be re-configured. As configure_endpoints() may now get called multiple times, move it outside __init and move serial_alloc_tty() call into __init. Code has assumption that endpoint mapping remains unchanged with consecutive calls of configure_endpoints().

2014-11-07fotg210: Make Xen notification consistent with EHCIChris Rorvick1-0/+5
If CONFIG_XEN_DOM0 is enabled, the ehci-dbgp driver notifies Xen of controller reset events via xen_dbgp_reset_prep() and xen_dbgp_external_startup() (via calls to xen_dbgp_op().) Otherwise <linux/usb/ehci_def.h> defines them as no-ops to disable this logic. The fotg210 driver copies much of the dbgp code from ehci_def.h, but it unconditionally defines the Xen hooks as no-ops, effectively disabling these notifications when CONFIG_EARLY_PRINTK_DBGP is disabled. When enabled, though, notifying Xen is dependent on CONFIG_XEN_DOM0 due to fotg210 leveraging the ehci-dbgp driver. The following table compares the implementations of xen_dbgp_reset_prep() and xen_dbgp_external_startup() in the ehci-dbgp and fotg210 drivers under the relevant configurations: EARLY_PRINTK_DBGP?
