  • 9841f37a1   usb: ehci: Add support for SINGLE_STEP_SET_FEATURE test of EHSET ... Browse Code »

    The USB Embedded High-speed Host Electrical Test (EHSET) defines the
    SINGLE_STEP_SET_FEATURE test as follows:

    1) The host enumerates the test device with VID:0x1A0A, PID:0x0108
    2) The host sends the SETUP stage of a GetDescriptor(Device)
    3) The device ACKs the request
    4) The host issues SOFs for 15 seconds allowing the test operator to
    raise the scope trigger just above the SOF voltage level
    5) The host sends the IN packet
    6) The device sends data in response, triggering the scope
    7) The host sends an ACK in response to the data

    This patch adds additional handling to the EHCI hub driver and allows
    the EHSET driver to initiate this test mode by issuing a a SetFeature
    request to the root hub with a Test Selector value of 0x06. From there
    it mimics ehci_urb_enqueue() but separately submits QTDs for the
    SETUP and DATA/STATUS stages in order to insert a delay in between.

  • 3f0d1c67f   usb: misc: usb3503: Support operation with no I2C control ... Browse Code »

    Refactor so that register writes for configuration are only performed if
    the device has a regmap provided and also register as a platform driver.
    This allows the driver to be used to manage GPIO based control of the
    device.

  • 1353aa538   usb: misc: EHSET Test Fixture device driver for host compliance ... Browse Code »

    An Embedded Host High-Speed Electrical Test (EHSET) test fixture is
    used to initiate test modes on a host controller in order to perform
    the high speed electrical testing procedure for USB-IF compliance.
    When this test fixture is connected to a host, it can enumerate as
    one of several selectable VID/PID pairs, each corresponding to one
    of the following test modes:

    * TEST_SE0_NAK
    * TEST_J
    * TEST_K
    * TEST_PACKET
    * HS_HOST_PORT_SUSPEND_RESUME
    * SINGLE_STEP_GET_DEV_DESC
    * SINGLE_STEP_SET_FEATURE

    The USB EHSET procedure can be found here:

  • d1e183c8d   console/font: Refactor font support code selection logic ... Browse Code »

    The current Makefile rules to build font support are messy and buggy.
    Replace them by Kconfig rules:
    - Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
    code,
    - Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
    - Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
    font,
    - Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
    - Always process drivers/video/console/Makefile, as some drivers need
    fonts even if CONFIG_VT is not set.

    This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
    drivers):

    drivers/built-in.o: In function `solo_osd_print':
    drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font'

    This fixes (if CONFIG_VT=n):

    drivers/built-in.o: In function `vivi_init':
    vivi.c:(.init.text+0x1a3da): undefined reference to `find_font'

  • 06a962fa7   usb: misc: usb3503: Remove 100ms sleep on reset, conform to data sheet ... Browse Code »

    The usb3503 driver sleeps a flat 100ms when resetting the chip, with a
    comment about waiting for the reference clock. This seems to be a
    board-specific detail that should not hold up boot across all platforms.
    This patch reduces the sleep to the 4ms initialization delay that the
    chip itself actually requires (as per its data sheet). If certain boards
    require more time to set up the reference clock, they should change this
    through local patches or add a proper, configurable synchronization
    mechanism.
