This is the driver for the USB comparator built into the palmas chip. It
handles the various USB OTG events that can be generated by cable
insertion/removal.
I have following feedback on this driver to use this on Tegra platform:
1. Can we have very simple driver for detecting VBUS and ID and just
generate notification. No VBUS control logic or lots of USB related
configurations?
2. We will need the VBUS control as optional if it is require for TI
platform. Currently it is mandatory and hence it is not suite in our
context.
3. There is VBUS control (enabled/disable) in VBUS detection also. When
palma detect the VBUS then why actually it need to enable VBUS as VBUS
is already supplied by HOST? It may be only need when palma detect the
ID pin and maybe want to enable VBUS but again VBUS control
(enable/disable) should be part of USB driver, out of extcon driver.
