usb-core: Add LINEAR_FRAME_INTR_BINTERVAL USB quirk

2017-03-14T09:07:31Z

Some USB 2.0 devices erroneously report millisecond values in bInterval. The generic config code manages to catch most of them, but in some cases it's not completely enough. The case at stake here is a USB 2.0 braille device, which wants to announce 10ms and thus sets bInterval to 10, but with the USB 2.0 computation that yields to 64ms. It happens that one can type fast enough to reach this interval and get the device buffers overflown, leading to problematic latencies. The generic config code does not catch this case because the 64ms is considered a sane enough value. This change thus adds a USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL quirk to mark devices which actually report milliseconds in bInterval, and marks Vario Ultra devices as needing it.

usb: chipidea: msm: Handle phy power states

2017-01-20T07:27:35Z

The ULPI phy on qcom platforms needs to be initialized and powered on after a USB reset and before we toggle the run/stop bit. Otherwise, the phy locks up and doesn't work properly. Hook the phy initialization into the RESET event and the phy power off into the STOPPED event. Acked-by: Peter Chen Cc: Greg Kroah-Hartman Signed-off-by: Stephen Boyd Signed-off-by: Peter Chen

usb: chipidea: Consolidate extcon notifiers

2017-01-20T07:13:49Z

The two extcon notifiers are almost the same except for the variable name for the cable structure and the id notifier inverts the cable->state logic. Make it the same and replace two functions with one to save some lines. This also makes it so that the id cable state is true when the id pin is pulled low, so we change the name of ->state to ->connected to properly reflect that we're interested in the cable being connected.

usb: chipidea: Add platform flag for wrapper phy management

2017-01-20T03:25:02Z

The ULPI phy on qcom platforms needs to be initialized and powered on after a USB reset and before we toggle the run/stop bit. Otherwise, the phy locks up and doesn't work properly. Therefore, add a flag to skip any phy power management in the core layer, leaving it up to the glue driver to manage.

usb: chipidea: Handle extcon events properly

2017-01-20T03:24:35Z

We're currently emulating the vbus and id interrupts in the OTGSC read API, but we also need to make sure that if we're handling the events with extcon that we don't enable the interrupts for those events in the hardware. Therefore, properly emulate this register if we're using extcon, but don't enable the interrupts. This allows me to get my cable connect/disconnect working properly without getting spurious interrupts on my device that uses an extcon for these two events.

Pull USB/PHY updates from Greg KH: "Here's the big set of USB/PHY patches for 4.10-rc1. A number of new drivers are here in this set of changes. We have a new USB controller type "mtu3", a new usb-serial driver, and the usual churn in the gadget subsystem and the xhci host controller driver, along with a few other new small drivers added. And lots of little other changes all over the USB and PHY driver tree.

NET: usb: cdc_mbim: add quirk for supporting Telit LE922A

2016-12-08T18:02:25Z

Telit LE922A MBIM based composition does not work properly with altsetting toggle done in cdc_ncm_bind_common. This patch adds CDC_MBIM_FLAG_AVOID_ALTSETTING_TOGGLE quirk to avoid this procedure that, instead, is mandatory for other modems.

usb: hcd.h: construct hub class request constants from simpler constants

2016-12-05T15:37:10Z

Currently, each hub class request constant is defined by a line like: #define ClearHubFeature (0x2000 | USB_REQ_CLEAR_FEATURE) The "magic" number for the high byte is one of 0x20, 0xa0, 0x23, 0xa3. The 0x80 bit that changes inditace USB_DIR_IN, and the 0x03 that pops up is the difference between USB_RECIP_DEVICE (0x00) and USB_RECIP_OTHER (0x03). The constant 0x20 bit is USB_TYPE_CLASS. This patch eliminates those magic numbers by defining a macro to help construct these hub class request from simpler constants. Note that USB_RT_HUB is defined as (USB_TYPE_CLASS | USB_RECIP_DEVICE) and that USB_RT_PORT is defined as (USB_TYPE_CLASS | USB_RECIP_OTHER).

usb: gadget: add a new quirk to avoid skb_reserve in u_ether.c

2016-08-31T07:06:03Z

Some platforms (e.g. USB-DMAC on R-Car SoCs) has memory alignment restriction. If memory alignment is not match, the usb peripheral driver decides not to use the DMA controller. Then, the performance is not good. In the case of u_ether.c, since it calls skb_reserve() in rx_submit(), it is possible to cause memory alignment mismatch. So, this patch adds a new quirk "quirk_avoids_skb_reserve" to avoid skb_reserve() calling in u_ether.c to improve performance. A peripheral driver will set this flag and network gadget drivers (e.g. f_ncm.c) will reference the flag via gadget_avoids_skb_reserve(). Signed-off-by: Yoshihiro Shimoda Signed-off-by: Felipe Balbi
