kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05+00:00

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

USB: core: Add input prompt and help text for USB_OTG config

2010-12-16T23:45:44+00:00

bd6882 commit (usb: gadget: fix Kconfig warning) removes
the duplicate USB_OTG config from gadget/Kconfig.  But
does not copy the input prompt and help text to the original
config defined in core/Kconfig. Add them now.

USB: update Kconfig help text for CONFIG_USB_SUSPEND

2010-09-24T18:05:01+00:00

This patch (as1429) updates the Kconfig help text for
CONFIG_USB_SUSPEND.  The power/level file is now deprecated; we should
tell people to use power/control instead.

USB: fix build on OMAPs if CONFIG_PM_RUNTIME is not set

2010-04-30T16:25:11+00:00

With patch as1329 (USB: convert to the runtime PM framework),
we make USB_SUSPEND depend on PM_RUNTIME instead of CONFIG_PM.

Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND.

If PM_RUNTIME is not enabled, and we try to enable USB_OTG,
we will end up with CONFIG_USB_SUSPEND selected. This is
due to a known bug with the select statement.

This makes the build break on various OMAP configs (which
have CONFIG_USB_OTG set by default, but do not yet have
CONFIG_PM_RUNTIME enabled).

Avoid this by changing the logic for CONFIG_USB_OTG from
"select USB_SUSPEND" to "depends on USB_SUSPEND"

USB: convert to the runtime PM framework

2010-03-02T22:54:12+00:00

This patch (as1329) converts the USB stack over to the PM core's
runtime PM framework.  This involves numerous changes throughout
usbcore, especially to hub.c and driver.c.  Perhaps the most notable
change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME
instead of CONFIG_PM.

Several fields in the usb_device and usb_interface structures are no
longer needed.  Some code which used to depend on CONFIG_USB_PM now
depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header
files).

The only visible change in behavior should be that following a system
sleep (resume from RAM or resume from hibernation), autosuspended USB
devices will be resumed just like everything else.  They won't remain
suspended.  But if they aren't in use then they will naturally
autosuspend again in a few seconds.

Revert USB: usbfs: deprecate and hide option for !embedded

2009-07-12T22:16:39+00:00

This reverts commit cc71329b3b89b4a5be849b617f2c4f151f0b9213, so that
Red Hat machines can boot properly.  It seems that the Red Hat initrd
code tries to watch the /proc/bus/usb/devices file to monitor usb
devices showing up.  While this task is prone to lots of races and does
not show the true state of the system, they seem to like it.

So for now, don't move this option under the EMBEDDED config option.

USB: usbfs: deprecate and hide option for !embedded

2009-06-16T04:44:41+00:00

Modern systems do not use usbfs; the entries within it are files,
not device nodes, and do not support ACLs which are the default way to
provide access to USB devices to untrusted users.

It is replaced by device-nodes maintained by udev in /dev/bus/usb,
libusb uses this device nodes.

Mark the option as deprecated, and hide entirely for non-embedded builds
(which may not be using udev but require raw USB device access).

USB: partial USB embedded host support

2008-04-25T04:16:40+00:00

This provides better support for USB "Embedded Host" functionality, which
is a subset of the USB OTG options:

 * External hub support can be disabled;

 * USB peripherals not whitelisted in "otg_whitelist.h" will be rejected
   during enumeration.

These options can allow some savings in software and support.
