Allow userspace not beeing root to update the SIM voltage level through sysfs. Modem needs to go via userspace to update the voltage level and that program is currently not root. Also change sysfs return value when a faulty input is given.

2012-06-05shrm-net : remove netif_carrier_off/on callsHemant Ramdasi
This patch removes netif_carrier_off() call from machine suspend sequence. Also removes netif_carrier_on() call from resume sequence. This error is introduced because of the below behaviour. Important control message PNS_PEP_STATUS_IND message from phonet stack is getting dropped sometimes in the APE sleep-wakeup transition. It happens because, the Qdisc (between Phonet and SHRM) changes to "noop" when APE goes to sleep. The normal Qdisc in operation in pfifo_fast. When APE wakes up, the transition to pfast_fifo is not fast enough as it is done in a workqueue. So before the switch happens, APE receives 3 packets very quickly and must grant credits in any of the 3 packets. This does not happen. Hence modem cannot send any new packet as it has exhausted all its credits and APE cannot send credit-grant message as it will not receive any new packet. This leads to a deadlock situation for IP data transfer.

2012-06-05u8500-shrm: add timer to check if modem has stuck or hangArun Murthy
On APE sending msg_pend notification, the only way when APE gets to know that modem is not responsive, is when it ends up with a FIFO full. In order to get this FIFO full on common channel it might take 30min. Hence add a timer and start the timer on msg_pend_notification and cancel the timer at read_noti. If timer expires within this time then its for sure that modem is not responsive. Initiate MSR in that case. The current timer value is 6sec. Since there are two timers and on expiry of either of the timer, modem_reset is called, have added flag so as to ensure that modem_rest is not called simultaneously on exit of both the timer in short span of time.

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.

2012-06-05u8500-shrm: Stop network queue on modem resetArun Murthy
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.
