Hi,
I am working on Davinci EVM and using davinci git 2.6.23. Can I
dynamically enable/disable USB ports on Davinci? (Disable at HW level,
use PSC to disable the clock). Does current Davinci USB stack for the
MUSB controller support loading/unloading of the HCD controller
dynamically? If I need to disable the ports,
I am planing to follow these steps:
1. Stop any data transfers to USB accessories
2. Unload any accessory drivers
3. Unload USB HCD driver
4. Disable clock to USB port and also power down PHY
To reenable:
1. ENable clock to USb module, Power ON PHY
2. Insmod USB HCD driver
3. Let udev takecare of insmoding drivers for any accessories attached.
Will this work?
