* staging: comedi: vmk80xx: remove digital output (*insn_read)H Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | The comedi core can use the (*insn_bits) function to emulate the (*insn_read) function. The digital output (*insn_bits) function properly handles the VMK8061_MODEL to read the digital output states before returning. Remove the unnecessary (*insn_read) function. It's also not necessary to set the SDF_READABLE flag so remove the entire conditional in the attach.

* staging: comedi: vmk80xx: cleanup pwm subdevice initH Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | | | Change the 'pwm_bits' in the boardinfo to 'pwm_maxdata' so that the calculation of s->maxdata can be removed. Also, change the type to match the comedi_subdevice type. For aesthetic reasons, rename the 'pwm_chans' boardinfo and change its type also. Remove the '0' values in the boardinfo. Rename the (*insn_read) and (*insn_write) functions for the pwm subdevice to make grepping easier. For aesthetic reasons, add some whitespace to the subdevice init.

* staging: comedi: vmk80xx: push usb (*probe) into comedi (*auto_attach)H Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | | | | | | | | Make the usb_driver (*probe) simply call comedi_usb_auto_config() and move all the (*probe) code into the (*auto_attach) function. This allows getting rid of the static private data array since we no longer do part of the initialization in the (*probe) and then finish it in the (*auto_attach). We can simply kzalloc the private data instead. The comedi core will then handle the kfree of the data when the driver is detached. We can also get rid of the static 'glb_mutex' since this mutex was only used to protect the static private data array. Change the parameters for a couple of the helper functions used during the auto attach. Now that the comedi_device is available we can simply pass that pointer and get the specific pointers needed by the helper functions from it.

* staging: comedi: vmk80xx: remove private data 'attached'H Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | | | | | | The 'attached' flag in the private data is set after the comedi_driver (*auto_attach) function has completed successfully. The only places it's checked are in rudimentary_check(), which does some basic sanity checks before doing any of the subdevice operations, and vmk80xx_auto_attach(), which is the comedi_driver (*auto_attach) function. The (*auto_attach) function can only be called as the result of a successfull usb_driver (*probe). Part of the probe is to locate a free slot in the static private data array. All free slots are initialized to '0' so the 'attached' flag will always be cleared. Remove the unneccessary 'attached' flag in the private data.

* staging: comedi: vmk80xx: remove private data 'probed'H Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | | | | | | | The 'probed' variable is used in the usb driver (*probe) to detect an unused element in the static private data arry. This variable is then set after the usb driver has completed its (*probe) before calling comedi_usb_auto_config(). When the comedi core does the auto config it will call the (*auto_attach) function, vmk80xx_auto_attach(), which then locates the correct private data in the static array by checking to see if it has been 'probed' and that the 'intf' variable matches the usb_interface pointer for the usb device. Now that the private data is clean after failed usb probes and disconnects we don't have to worry about have a garbage 'intf' value in the private data that might match. Remove the 'probed' flag from the private data and just use the 'intf' pointer to detect the match.

* staging: comedi: vmk80xx: make sure private data is clean when detachedH Hartley Sweeten2013-02-05
| | | | | | | | | | | | | | | | | | | | | Currently the private data used in this driver is stored in a static array. During the usb (*probe) and empty location is found in this array for use by the usb device. Some initialization of the private data is then done before comedi_usb_auto_config() is called to allow the comedi core to attach its comedi_device to the usb device. The (*probe) can fail for various reasons. If it does, make sure that the private data is clean before returning an error. The usb (*disconnect) simply calls comedi_usb_auto_unconfig() to allow the comedi core to disconnect its comedi_device from the usb device. Since the private data points to the static array it cannot be kfree'ed during the detach. Instead make sure it clean before leaving the detach.

This driver already covers a large set of new parts (20 gyros, accelerometer and magnetometers) not currently covered by the existing drivers. The intent moving forward is to merge this with the other drivers for similar parts already in tree. The lis3l02dq driver currently in staging/iio will be trivial, the lis3 driver in misc more complex as it has a number of additional interfaces. Any merging in of the lis3 driver will rely on the not currently merged iio_input bridge driver and handling of freefall notifications etc. 2) A driver for the itg3200 gyroscope. Graduations from staging 1) Cleanup and move out of staging of the adxrs450 gyroscope driver. The cleanup required was all minor but there were a couple of fixes hidden in there. Core and driver additions 1) Initial work from Guenter Roeck on device tree support for IIO's provider/ consumer code. Focuses on the iio_hwmon driver and the max1363 adc driver. The full device tree syntax is currently under discussion but should follow shortly. Cleanups and fixes 1) Remove a noop function __iio_update_buffer 2) Couple of small fixes and cleanups for the max1363 "

This can result in bad data for chips with 10 bit resolution if those chips have higher bits set (seen with MAX1139). The receive buffer was defined as char array. This could result in unintentional sign extensions if the upper bit in a received byte was set. Since the chip is configured for unipolar mode, we never have to handle negative values, and sign extensions are never needed.
