Introduces the OMAP SSI driver in the kernel. The Synchronous Serial Interface (SSI) is a legacy version of HSI. As in the case of HSI, it is mainly used to connect Application engines (APE) with cellular modem engines (CMT) in cellular handsets. It provides a multichannel, full-duplex, multi-core communication with no reference clock. The OMAP SSI block is capable of reaching speeds of 110 Mbit/s.

2012-03-19u8500-shrm: maintain sleep statemachine in real timeArun Murthy
ac_sleep_disable_count is flag used t control the power management state machine this counter is increased in 3 places ca_wake_req ac_msg_pend_notify_0 ac-msg_pend_notify_1 and decremented in 3 places ac_read_notify_0 ac_read_notify_1 ca_sleep_req ac_msg_pend_notify is called from 2 places, shm_write_msg ac_read_notify it gets called from "shm_write_msg" when there is only one message in the shared memory and otherwise from "ac_read_notify" LOGS <6>[ 72.793395] send_ac_msg_pend_notify_1_work I:2 <6>[ 72.793609] shm_ac_read_notif_1_tasklet D:1 <6>[ 72.793731] send_ac_msg_pend_notify_1_work I:2 <6>[ 72.793853] send_ac_msg_pend_notify_1_work I:3 <6>[ 72.793914] shm_ac_read_notif_1_tasklet D:2 <6>[ 72.804840] send_ac_msg_pend_notify_1_work I:3 <6>[ 72.805053] shm_ac_read_notif_1_tasklet D:2 From the above logs send_ac_msg_pend_notify_1_work is called twice. No problem if this is called twice, but for state machine counter ac_sleep_disable_count this causes problem which doesnt allow the system to enter sleep. This function is called twice in a real time seq, first time from the ac_read_notify, here assume that there is only one message, and hence after notifying modem will call ac_msg_pend_notify. Modem on receiving this interrupt will update the shared read pointer and send the ack. After updating the shared read pointer and before APE receiving the ACK, there is some msg write req coming to shrm. shm driver shm_write_msg is called. Here it finds that this is the only message in shared memory, because the shared read and write pointer are same. Hence send_ac_msg_pend_notify_1_work is called again. Even though msg_pend is notified twice we receive read_notification only onece. Counter ac_sleep_disable_count is incremented in ca_wake_req to 1. Then in ac_msg_pend_notify to 2, then decremented in ac_read_notify. Hence it doesnt increase beyond 2 Fix would be to check if ac_msg_pend is called twice before ac_read_notify is received, then in that case dont increment the ac_sleep_disable_count in ac_msg_pend_notify.

On shrm receiving modem reset interrupt, it will disable interrupts and schedule a tasklet for initiating MSR if enabled. The tasklet function includes stopping the network queue. But as soon as ISR is served, if phonet starts ending message, shrm will return with a -ve value. Hence phonet retries sending the same message again. This will lead to a dedlock and finally ends up with a watchdog timeout. Hence stop the network queue on receiving modem reset interrupt in the interrupt handler.

2012-03-19shrm: use kthread_worker instead of workqueueThierry STRUDEL
Workqueue updates no longer guarantee fixed workqueue to worker kthread association, so giving RT priority to the irq worker won't work. Use kthread_worker which guarantees specific kthread association instead. This also makes setting the priority cleaner.
