mei: cancel stall timers in mei_reset

2013-10-05T14:13:10+00:00

commit 4a704575cc1afb3b848f096778fa9b8d7b3d5813 upstream.

in mei_reset in order to cancel timer ticking and hence
avoid recursive reset calls.

mei: bus: stop wait for read during cl state transition

2013-10-05T14:13:10+00:00

commit e2b31644e999e8bfe3efce880fb32840299abf41 upstream.

Bus layer omitted check for client state transition while waiting
for read completion
The client state transition may occur for example as result
of firmware initiated reset

Add mei_cl_is_transitioning wrapper to reduce the code
repetition.:

mei: make me client counters less error prone

2013-10-05T14:13:10+00:00

commit 1aee351a739153529fbb98ee461777b2abd5e1c9 upstream.

1. u8 counters are prone to hard to detect overflow:
 make them unsigned long to match bit_ functions argument type

2. don't check me_clients_num for negativity, it is unsigned.

3. init all the me client counters from one place

drivers/misc/hpilo: Correct panic when an AUX iLO is detected

2013-09-08T05:09:59+00:00

commit eefbc594abbb1b7e6e7eeadb65ae7c7538474210 upstream.

 Using an uninitialized variable 'devnum' after 'goto out;' was causing
 panic.  Just go ahead and return, we need to ignore AUX iLO devs.

mei: me: fix hardware reset flow

2013-09-08T05:09:59+00:00

commit ff96066e3171acdea356b331163495957cb833d0 upstream.

Both H_IS and H_IE needs to be set to receive H_RDY
interrupt

1. Assert H_IS to clear the interrupts during hw reset
and use mei_me_reg_write instead of mei_hcsr_set as the later
strips down the H_IS

2. fix interrupt disablement embarrassing typo
  hcsr |= ~H_IE -> hcsr &= ~H_IE;
this will remove the unwanted interrupt on power down

3. remove useless debug print outs

mei: me: fix waiting for hw ready

2013-08-29T16:47:40+00:00

commit dab9bf41b23fe700c4a74133e41eb6a21706031e upstream.

1. MEI_INTEROP_TIMEOUT is in seconds not in jiffies
so we use mei_secs_to_jiffies macro
While cold boot is fast this is relevant in resume
2. wait_event_interruptible_timeout can return with
-ERESTARTSYS so do not override it with -ETIMEDOUT
3.Adjust error message

commit 315a383ad7dbd484fafb93ef08038e3dbafbb7a8 upstream.

ME HW ready bit is down after hw reset was asserted or on error.
Only on error we need to enter the reset flow, additional reset
need to be prevented when reset was triggered during
initialization , power up/down or a reset is already in progress

 "Here are some small mei driver fixes for 3.10-rc6 that fix some
  reported problems"

mei: me: clear interrupts on the resume path

2013-06-14T05:31:07+00:00

We need to clear pending interrupts on the resume
path. This brings the device into defined state
before starting the reset flow

This should solve suspend/resume issues:

mei_me : wait hw ready failed. status = 0x0
mei_me : version message write failed
