Changes for v5:
- By default otg feature are enabled if usb controller can support it.
use of_usb_set_otg_caps to set otg_rev and disable features by DT.
- Update legacy drivers, allocate and init otg descriptor in bind
function, free it in unbind, to make alloation and free are symmetric.
- Add Roger's reviewed-by.
Changes for v4:
- Add usb_otg_caps structure for all otg related capability attributes.
- Use one interface: of_usb_get_otg_caps to get all otg capabilities
from DT, including otg_rev, hnp/srp/adp support.
- Add usb_otg_descriptor_alloc interface to allocate otg descriptor
for better code sharing.
- Improve description of dt-binding doc.
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. Add usb_otg20_descriptor definition for OTG 2.0 which introduces bcdOTG
field for otg revision, bcdOTG 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. Remove static usb otg descriptor definition, but allocate and init it
according to otg capabilities in each gadget driver, if otg capabilities
is not defined for legacy platforms, the usb otg descriptor content is
kept the same as current static definition.
