* mei: move clients cleanup code from init.c to client.cTomas Winkler2013-02-061-0/+51
| | | | | | | | | during reset we clean up client data structures we move that code into wrappers in client and call the wrappers Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: rename to mei_host_buffer_is_empty to hbuf_is_readyTomas Winkler2013-02-061-7/+6
| | | | | | | | | 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 Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: drop the warning when cl is not initialized during unlinkingTomas Winkler2013-01-141-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems where wd and amthif is not initialized we will hit cl->dev == NULL. This condition is okay so we don't need to be laud about it.

* mei: normalize me host client linking routinesTomas Winkler2013-01-081-23/+30
| | | | | | | | | | | | | In order we can use the same code pattern for in-kernel and user space host clients we replace mei_cl_link_to_me with mei_cl_link function. We then have to keep me client lookupout of the new link function. The unlinking cannot be yet symetric due to amthif connection handling Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* mei: rename interface to hw-meTomas Winkler2013-01-081-1/+0
| | | | | | | | | | Rename hw-me.h to hw-me-regs.h as this file contains only register definitions. Files hw-me.[ch] now contains ME hw dependant functionality Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: implement mei_cl_connect functionTomas Winkler2013-01-081-154/+65
| | | | | | | | | | | Implement mei_cl_connect that warps host client parts of the connection and leave the ioctl specifics in the mei_ioctl_connect_client function. Move mei_ioctl_connect_client to main.c where it belongs Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: fix client functions namesTomas Winkler2013-01-081-85/+136
| | | | | | | | | | | | | | | | | Use common prefix for function names: mei_cl_ - for host clients mei_me_ - for me clients mei_io_ - for io callback functions Because mei_cl holds mei_device back pointer we can also drop the dev argument from the client functions add client.h header to export the clients API Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: move client functions to client.cTomas Winkler2013-01-081-0/+710
