mei: ME hardware reset needs to be synchronized

2013-03-15T18:18:08+00:00

This fixes failure during initialization on Lynx Point LP devices.

ME driver needs to release the device from the reset
only after the FW has completed its flow and indicated
it by delivering an interrupt to the host.

This is the correct behavior for all the ME devices yet the
the previous versions are less susceptive to the implementation
that ignored FW reset completion indication.

We add mei_me_hw_reset_release function which is called
after reset from the interrupt thread or directly
from mei_reset during power down.

mei: add mei_stop function to stop mei device

2013-03-15T18:18:07+00:00

mei_stop calls mei_reset with disabling the interrupts.
It will have the same effect as the open code it replaces in the mei_remove.

The reset sequence on remove is required for the Lynx Point LP devices
to clean the reset state.

mei_stop is called from mei_pci_suspend and mei_remove functions

mei: fix undefined wd symbols when MEI_ME is not set

2013-02-07T22:00:25+00:00

Currently watchdog client is compiled with MEI and not
with MEI_ME

Fixes error:
When CONFIG_WATCHDOG is not enabled:

ERROR: "watchdog_unregister_device" [drivers/misc/mei/mei.ko] undefined!
ERROR: "watchdog_register_device" [drivers/misc/mei/mei.ko] undefined

mei: move clients cleanup code from init.c to client.c

2013-02-06T19:24:33+00:00

during reset we clean up client data structures
we move that code into wrappers in client
and call the wrappers

mei: rename to mei_host_buffer_is_empty to hbuf_is_ready

2013-02-06T19:24:33+00:00

we rename the mei_host_buffer_is_empty to keep naming
convention of hbuf and also make the query more generic
to be correct also for other under laying hardware

mei: move interrupt handlers to be me hw specific

2013-02-06T19:24:33+00:00

interrupt handler are  platform specifics so we move
them to hw-mei.c. For sake of that we need to export
write, read, and complete handlers from the interrupt.c

mei: separate compilation of the ME hardware specifics

2013-02-06T19:23:47+00:00

We add struct mei_hw_ops to virtualize access to hw specific
configurations. This allows us to separate the compilation
of the ME interface from the ME hardware specifics

mei: initial extract of ME hw specifics from mei_device

2013-02-06T19:23:14+00:00

This is initial step of move the ME hw specifics
out of mei_device structure into mei_me_hw
