usb: chipidea: otg: add A idle to B disconnect timer

2016-03-04T13:14:38+00:00

B-device detects that bus is idle for more than TB_AIDL_BDIS min and
begins HNP by turning off pullup on DP, this allows the bus to discharge
to the SE0 state. This timer was missed and failed with PET test:
6.8.5 B-UUT HNP of USB OTG and EH automated compliance plan v1.2,
this patch is to fix this timing issue.

kbuild: Allow to specify composite modules with modname-m

2015-11-25T10:23:25+00:00

This allows to write

  drm-$(CONFIG_AGP) += drm_agpsupport.o

without having to handle CONFIG_AGP=y vs. CONFIG_AGP=m. Only support
this syntax for modules, since built-in code depending on something
modular cannot work and init/Makefile actually relies on the current
semantics. There are a few drivers which adapted to the current
semantics out of necessity; these are fixed to also work when the
respective subsystem is modular.

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.
