2015-06-24MLK-11137 usb: chipidea: host: add own hc_driver for each hcdPeter Chen
There are several benefits for doing like this: - hc_driver can be customized for each hcd - Other hcd hc_driver's initialization will not affect current one. We run out NULL pointer dereference problem when one hcd is started by module_init, and the other is started by otg thread at SMP platform. The reason for this problem is ehci_init_driver will do memory copy for current uniform hc_driver, and this memory copy will do memset (as 0) first, so when the first hcd is running usb_add_hcd, and the second hcd may clear the uniform hc_driver's space (at ehci_init_driver), then the first hcd will meet NULL pointer at the same time.

The current condition may not true even we have driven vbus on already. The vbus drive operation may be async, eg through i2c gpio expendor, so the vbus may not be valid when we unload usb module.

While A device as peripheral ends session by a_bus_drop, it will go back to host role by transition to a_wait_vfall state, then ehci host driver may access portsc status after controller enters suspend , this will result in system hang since its clock is gated off. This patch use existing autosuspend to delay the controller suspend if it comes to a_wait_vfall state.

With commit "95b62fe MLK-10750 usb: chipidea: otg: remove otg fsm before destory gdaget and host", the otg fsm will be removed first, but when the host is removing, it will trigger pcd interrupt, and otg work is still queued to ci_otg workqueue(otg state is OTG_STATE_A_HOST), but at that time, ci_otg workqueue has been destroyed. In this commit, we make sure the otg work is not queued if ci->wq is NULL, and keep otg state is OTG_STATE_UNDEFINED after otg fsm has been removed.

Current code just do not do reusme signaling for clear suspend feature if it's a OTG port with b_hnp_enable set, this result in OTG host cannot clear suspend and resume OTG device after system resume from sleep, then host will disconnect the OTG B-device and enumerate it again.

This patch is to clear the flag b_conn when turns off vbus to end a session. when otg fsm is a_host -> a_suspend -> a_wait_vfall -> a_idle, current otg fsm implementation does not handle disconnect event since the disconnection does not happen while a_host state, so the b_conn is still set when in a_idle, this patch clear b_conn flag after turn off vbus.
