usb: chipidea: otg: remove mutex unlock and lock while stop and start role

2015-04-28T10:51:30+00:00

Wrongly release mutex lock during otg_statemachine may result in re-enter
otg_statemachine, which is not allowed, we should do next state transtition
after previous one completed.

usb: chipidea: use hrtimer for otg fsm timers

2015-03-26T09:54:39+00:00

Current otg fsm timers are using controller 1ms irq and count it, this patch
is to replace it with hrtimer solution, use one hrtimer for all otg timers.

usb: otg-fsm: move 2 otg fsm timers definition to otg_fsm_timer

2015-03-26T09:54:39+00:00

B_DATA_PLS(data-line pulse time) and B_SSEND_SRP(session end to SRP init) are
also from OTG&EH 2.0 Specification and they are not chipidea specific.

usb: chipidea: otg: remove unnecessary B_SESS_VLD timer

2015-03-26T09:54:01+00:00

Since BSV irq is enabled for B-device all the time, so B_SESS_VLD timer
is not required, and also no need to check BSV status when B_ASE0_BRST
timer timeout.

usb: chipidea: support runtime power management for otg fsm mode

2015-03-18T15:19:12+00:00

This patch adds runtime power management support for otg fsm mode, since
A-device in a_idle state cannot detect data pulse irq after suspended, here
enable wakeup by connection before suspend to make it can be resumed by DP;
and handle wakeup from that state like SRP.

usb: chipidea: parameter 'mode' isn't needed for hw_device_reset

2014-11-26T17:28:12+00:00

The hw_device_reset is dedicated to be used at device mode initializaiton,
so delete the parameter 'mode'. For host driver, the ehci driver will
handle all things.

Merge tag 'usb-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

usb: patches for v3.19 merge window

This time, a very pull request with 216 non-merge
commits. Most of the commits contained here are
sparse or coccinelle fixes ranging from missing
'static' to returning 0 in case of errors.

More importantly, we have the removal the now
unnecessary 'driver' argument to ->udc_stop().

DWC2 learned about Dual-Role builds. Users of
this IP can now have a single driver built for
host and device roles.

DWC3 got support for two new HW platforms: Exynos7
and AMD.

The Broadcom USB 3.0 Device Controller IP is now
supported and so is PLX USB338x, which means DWC3
has lost is badge as the only USB 3.0 peripheral
IP supported on Linux.

Thanks for Tony Lindgren's work, we can now have
a distro-like kernel where all MUSB glue layers
can be built into the same kernel (statically
or dynamically linked) and it'll work in PIO (DMA
will come probably on v3.20).

Other than these, the usual set of cleanups and
non-critical fixes.
