2020-01-15usb: musb: omap2430: Get rid of musb .set_vbus for omap2430 glueTony Lindgren
We currently have musb_set_vbus() called from two different paths. Mostly it gets called from the USB PHY via omap_musb_set_mailbox(), but in some cases it can get also called from musb_stage0_irq() rather via .set_vbus: (musb_set_host [musb_hdrc]) (omap2430_musb_set_vbus [omap2430]) (musb_stage0_irq [musb_hdrc]) (musb_interrupt [musb_hdrc]) (omap2430_musb_interrupt [omap2430]) This is racy and will not work with introducing generic helper functions for musb_set_host() and musb_set_peripheral(). We want to get rid of the busy loops in favor of usleep_range(). Let's just get rid of .set_vbus for omap2430 glue layer and let the PHY code handle VBUS with musb_set_vbus(). Note that in the follow-up patch we can completely remove omap2430_musb_set_vbus(), but let's do it in a separate patch as this change may actually turn out to be needed as a fix.

2020-01-15usb: dwc2: Drop unlock/lock upon queueing a work itemLukas Wunner
The original dwc_otg driver used a DWC_WORKQ_SCHEDULE() wrapper to queue work items. Because that wrapper acquired the driver's global spinlock, an unlock/lock dance was necessary whenever a work item was queued up while the global spinlock was already held. The dwc2 driver dropped DWC_WORKQ_SCHEDULE() in favor of a direct call to queue_work(), but retained the (now gratuitous) unlock/lock dance in dwc2_handle_conn_id_status_change_intr(). Drop it.

2020-01-15usb: dwc3: gadget: Remove END_TRANSFER delayThinh Nguyen
We had a 100us delay to synchronize the END_TRANSFER command completion before giving back requests to the function drivers. Now, the controller driver can handle cancelled TRBs with the requests' cancelled_list and it can also wait until the END_TRANSFER completion before starting new transfers. Synchronization can simply base on the controller's command completion interrupt. The 100us delay is no longer needed. Remove this arbitrary delay.

While the END_TRANSFER command is sent but not completed, any request dequeue during this time will cause the driver to issue the END_TRANSFER command.

2020-01-15usb: gadget: f_fs: set req->num_sgs as 0 for non-sg transferPeter Chen
The UDC core uses req->num_sgs to judge if scatter buffer list is used. Eg: usb_gadget_map_request_by_dev. For f_fs sync io mode, the request is re-used for each request, so if the 1st request->length > PAGE_SIZE, and the 2nd request->length is <= PAGE_SIZE, the f_fs uses the 1st req->num_sgs for the 2nd request, it causes the UDC core get the wrong req->num_sgs value (The 2nd request doesn't use sg). For f_fs async io mode, it is not harm to initialize req->num_sgs as 0 either, in case, the UDC driver doesn't zeroed request structure.

So get rid of the platform data, which rids us of another consumer of the legacy GPIO API at the same time. Make sure we only inlcude <linux/gpio/consumer.h> which is all we use. Alter the usb_phy_gen_create_phy() function prototype to not pass any platform data as this is just hardcoded to NULL at all locations calling it in the kernel. Move the devm_gpiod_get* calls out of the if (of_node) parenthesis, as these calls are generic and do not depend on device tree, they are used by any hardware description.

2020-01-10nvmet: fix per feat data len for get_featureAmit Engel
The existing implementation for the get_feature admin-cmd does not use per-feature data len. This patch introduces a new helper function nvmet_feat_data_len(), which is used to calculate per feature data len. Right now we only set data len for fid 0x81 (NVME_FEAT_HOST_ID).
