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:

It's not all that big, nothing major changed in the tty api, which is a
nice change, just a number of serial driver fixes and updates and new

All of these have been in the linux-next releases for a while, with the

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'

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.

The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test. It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them). This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.
Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it. But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.
Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting. Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody. In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.
The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.
