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-lengt
After introduce usb otg properties, update ci_otg_is_fsm_mode conditions
to be depending on both usb hardware properties and usb driver config,
also resolve a compile issue in debug.c after the API change.

Hi Alan and community,
I am using mass storage kernel module of v4.0.1 for Freescale i.MX6SL
for a commercial product. As this is commercial product, thus USB host
compatibility is important.
1) It seems that Windows 7 host can *not* auto-mount if I pass
parameters as below:
modprobe g_mass
Actually as of the current kernel, uas support/driver is a
prerequisite of TRIM, because skip_vdp_page in scsiglue.c prevent
sd_read_block_limits(), which configure various values necessary for
blkdev_issue_discard() (and other filesystem-specific discard
functions/ioctls) through sd_config_discard
