2012-11-16Staging: ipack: move out of stagingGreg Kroah-Hartman1-481/+0
The ipack subsystem is cleaned up enough to now move out of the staging tree, and into drivers/ipack. Cc: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Cc: Jens Taprogge <jens.taprogge@taprogge.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-11-13Staging: ipack: ipack: fix coding style issuesJohan Meiring1-2/+3
This uses linux/io.h instead of asm/io.h and cleans up an 80+ character issue. Signed-off-by: Johan Meiring <johanmeiring@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-10-19Staging: ipack: fix wrong return value.Samuel Iglesias Gonsalvez1-1/+1
In case it is not possible to remap the memory, it returns 0 and the driver thinks that everything went fine. Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-10-19Staging: ipack: Make ipack_device_register() analogous to device_register().Jens Taprogge1-21/+9
ipack_device_register() is no longer creating the struct ipack_device but only registering it. Instead of releasing memory directly the new ipack_device->release callback is called. This is preparational work for later patches.

2012-09-13staging: ipack: remove irq field in struct ipack_device.Jens Taprogge1-2/+1
The field irq currently is identical to the slot number. It does not seem to have any real use. The number is written to hardware in ipoctal but it seems the value that is written does not matter.

2012-09-11Staging: ipack: check the device ID space CRC.Jens Taprogge1-1/+58
We check the CRC and store the result of the check in struct ipac_device. A warning is emitted if the check fails. However we leave it to the IPack module device to refuse to initialize due to a bad CRC. I have seen otherwise good modules with bad CRCs.

2012-09-11Staging: ipack: reset previous timeouts during device registration.Jens Taprogge1-0/+2
Resetting the previous timeout we avoid to read the timeout status register and see timeout errors that don't correspond to the present state of the device.

2012-09-11Staging: ipack: Switch to 8MHz operation before reading ID.Jens Taprogge1-3/+8
Reading the ID space at 8 MHz is always supported. Most carriers will boot up in 8MHz mode. Still, play it safe and ensure we are operating at 8Mhz.

2012-09-04Staging: ipack: Implement device matching on the bus level.Jens Taprogge1-10/+33
Devices are match based upon their vendor and device ids. Since the individual drivers provide a list of supported ids they do not need to implement the matching themselves.

2012-06-07Staging: ipack: delete the call to remove() in ipack_driver_registerSamuel Iglesias Gonsalvez1-2/+0
When a bus driver calls ipack_driver_register(), it should manages the returning NULL value to undo all the operations it did before this call, and print the corresponding trace. It is not a task for the ipack driver to call the remove() function here.

2012-06-07Staging: ipack: use idr interface for numbering busesSamuel Iglesias Gonsalvez1-34/+6
Use idr interface to give the bus number. That way, we remove the limitation of 64 buses. The mutex is removed because the ida interface uses spinlocks inside, so it is not needed an extra lock.

2012-06-07Staging: ipack: return proper value in match() functionSamuel Iglesias Gonsalvez1-1/+1
It should return the same value given by the match function of the ipack_driver that has been called. Returning 0 here, means that the match has failed and it could be succeed.
