USB: fsl_udc_core: fix build breakage when building for ARM arch

2011-07-01T21:20:39+00:00

Commit 09ba0def (USB: fsl_udc_core: prepare for SoCs with
BE registers and descriptors) introduced build breakage
on ARM arch. Fix it by setting accessors using a static
inline function which is a nop when compiling the driver
for ARM arch.

Commit 2ea6698 (USB: fsl_udc_core: support device mode of
MPC5121E DR USB Controller) caused another breakage on ARM
by using flush_dcache_range(). Don't use it, convert to the
DMA API usage instead. USB2.0CV Halt Endpoint Test succeeds
on PPC. Tested both on ARM i.MX31 and mpc5121 PPC, also with
CONFIG_DMA_API_DEBUG enabled.

USB: CONFIG_USB_GADGET_DUALSPEED is not user-configurable

2011-06-07T16:05:44+00:00

This patch (as1468) changes the Kconfig definition for
USB_GADGET_DUALSPEED.  This option is determined entirely by which
device controller drivers are to be built, through Select statements;
it does not need to be (and should not be) configurable by the user.

Also, the "default n" line is superfluous -- everything defaults to N.

USB: dummy-hcd needs the has_tt flag

2011-06-07T16:05:43+00:00

Like with other host controllers capable of operating at both high
speed and full speed, we need to indicate that the emulated controller
presented by dummy-hcd has this ability.  Otherwise usbcore will not
accept full-speed gadgets under dummy-hcd.  This patch (as1469) sets
the appropriate has_tt flag.

usb/s3c-hsudc: fix error path

2011-06-06T23:28:03+00:00

I doubt the clock is optional. In case it is it should not return with
an error code because we leak everything.

usb/mv_udc_core: fix compile

|drivers/usb/gadget/mv_udc_core.c:2108: error: label `error' used but not defined

This seems to be broken since the initial commit. I changed this to a
simple return. The other user is the probe code which lets ->probe()
fail on error here.

USB: s3c-hsotg: Tone down debugging

2011-06-06T23:26:59+00:00

Currently the s3c-hsotg driver is extremely chatty, producing voluminous
with large register dumps even in default operation. Tone this down so
we're not chatty unless DEBUG is defined.

usb-gadget: unlock data->lock mutex on error path in ep_write()

2011-06-06T22:59:40+00:00

ep_write() acquires data->lock mutex in get_ready_ep() and releases it
on all paths except for one: when usb_endpoint_xfer_isoc() failed. The
patch adds mutex_unlock(&data->lock) at that path.

It is similar to commit 00cc7a5 ("usb-gadget: unlock data->lock mutex on error path in ep_read()"),
it was not fixed at that time by accident.
