USB: c67x00: add proper delays to HPI read/write

2014-01-08T00:15:39+00:00

According to CY7C67300 specification HPI read and write cycle duration
Tcyc must be at least 6T long, where T is 1/48MHz, which is 125ns.
Without this delay fast host processor cannot write to chip registers.
Add proper ndelay to hpi_{read,write}_reg.

USB: c67x00: remove CONFIG_USB_DEBUG dependancy

2013-12-20T19:46:19+00:00

This removes the usage of CONFIG_USB_DEBUG in the c67x00 driver.  There
was only one place, where the TD was dumped to the kernel log, and that
was using the dynamic debug infrastructure already, with the exception
of the call to print_hex_dump().  So move everything to the dynamic
debug infrastructure, including one odd printk(KERN_DEBUG...) line that
looks like it was forgotten about a long time ago.

usb: hcd: move controller wakeup setting initialization to individual driver

2013-12-09T02:06:46+00:00

Individual controller driver has different requirement for wakeup
setting, so move it from core to itself. In order to align with
current etting the default wakeup setting is enabled (except for
chipidea host).

Pass compile test with below commands:
	make O=outout/all allmodconfig
	make -j$CPU_NUM O=outout/all drivers/usb

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.
