The timeout values were 1000 and timeout issue occured many times on my s3c6410 Soc based board (mostly when booting whith USB cable not connected). This patch increase the values to 10000 to guarantee the success of reset. Having set timeout to 10000, I printed the remained timeout values which could cause timeout issue before this change (tested several times). the first timeout value remained: timeout = 8079 timeout = 8079 timeout = 8078 timeout = 8081 the second timeout value remained: timeout = 7940 timeout = 7945 timeout = 7940 timeout = 7938 Seeing from above values, I think the value 10000 is big enough.

This commit adds pullup method implementation for UDC s3c-hsotg driver. It is needed for e.g. CCG - Configurable Composite Gadget, when user space configuration change request device disconnection from USB bus (done via calling usb_gadget_connect/disconnect, which calls UDC's pullup method). Implementation of pullup method has caused removal of phy_enable and core_init methods from udc_start to pullup.

For SMP processors the spin_lock_irqsave is _only_ able to disable interrupt on a core on which it is executed. Therefore there may be a situation when other cores raise s3c-hsotg IRQ. Then there are several places where critical sections can be overwritten. To protect the above thread, a spin_lock in the interrupt handler has been added. Due to coherent memory view (especially L1 cache) the spin lock variable control access to IRQ handler only for one CPU core. In this way serialization to access this driver is provided and hence several spin_lock_* routines could be removed from IRQ handler's related functions. The complete_request_lock function has been removed since all its calls are performed from interrupt (spin lock protected) context.

This code allows Samsung SoC's to recover its state when device is disconnected and connected during transfer. It is necessary, in such a scenario, to reinitialize the USB core to assure correct initial state of the driver. This operation is needed since the disconnect interrupt is only available at HOST mode, which is not supported by this driver. A simple mechanism with jiffies has been used to perform core reset only once.

This commit targets following scenarios for IN requests: 1. HOST requests e.g. 256B (which is a multiple of MPS = 64B). Then NO ZLP shall be sent, since host expects exact number of bytes. 2. HOST requested 4096B, but our data for sending is 256B. In this situation ZLP shall be send to tell HOST that no more data is available and it shall not wait for more data. This prevents HOST from hanging.
