[PATCH v2 0/6] usb: s3c-hsotg: fixes for proper functioning

[Robert Baldyga]

Hello,

This is a second version of set of patches fixing s3c-hsotg USB driver
functioning. I've fixed issuses pointed by Felipe Balbi. For more information,
please check the change log at the end of the mail.

These patches add few fixes:
- Fix "protocol stall" handling, by enqueue new ep0 request when stalled
- Fix s3c_hsotg_write_fifo function to be usable in dedicated-fifo mode.
  Actually PTxFEmp/NPTxFEmp interrupts are enabled only in shared-fifo mode.
- Fix endpoint interrput handling, by disabling interrupts for endpoints which
  has no requests enqueued.
- Fixed DAINT register usage. Now only masked ep interrupts are handled.
- Fix "halt" property updating.
- Fix endpoint halt clearing, when it is not currently halted.

Best regards
