Changes for v3:
- For simple, add one more otg descriptor structure: usb_otg20_descriptor for OTG 2.0
and later release as Alan suggested.
- Use disable flags for OTG features property.
- Move out memory allocation from usb_otg_descriptor_init() to its caller.
Changes for v2:
- Use zero-length array as Peter Chen suggested to support usb_otg_descriptors
with different size.
- Add a new property otg-rev to specify the OTG release number with which the
device is compliant.
- Add a new interfate usb_otg_descriptor_add() to allocate and init usb_otg_descriptor
according to gadget otg options, for those do not use new otg options, keep
the usb_otg_descriptor setting unchanged.
- Remove static usb_otg_descriptor definitions in all legacy gadget driver, but
use usb_otg_descriptor_add to handle it while build usb configurations.
- Handle usb_otg_descriptor through usb_otg_descriptor_add and add it in each usb
configurations for configfs driver.
This is a follow-up of Macpaul Lin's previous patchset to resolve usb gadget driver
working with OTG 2.0, and set otg features by not only usb driver config but also usb
hardware property in DT, main changes:
1. keep one usb_otg_descriptor definition, add bcdOTG by zero-length array, which
can be passed via device tree.
2. OTG features(SRP/HNP/ADP) can be decided by combination of usb HW properties and
USB driver config.
3. Change the chipidea usb driver to use the updated mechanism.
4. Init usb_otg_descriptor according to otg options in each gadget driver.
