This patchset adds USB OTG HNP and SRP support on chipidea usb driver,
existing OTG port role swtich function by ID pin status kept unchanged,
based on that, if select CONFIG_USB_OTG_FSM, OTG HNP and SRP will be
supported.
Reference to:
"On-The-Go and Embedded Host Supplement to the USB Revision 2.0 Specification July 27, 2012
Revision 2.0 version 1.1a"
Changes since v1:
- Move out HNP polling patch from this series, which will be a seperated patchset
followed this one
- Change fsm timers global variables to be a structure embeded in ci_hdrc,
to make multiple OTG instances can exist in one system
- Change some otg fsm functions to be static
- Re-split timer init patch to avoid a later patch changing a previous one
in the same series
- Change timer structure memory allocation to be devm_kzalloc
- Update some format alignment and spelling errors
