Instead of requiring the map to unregister, simply unregister all map entries associated with the given iio device. This simplifies map removal and also works for maps generated through devicetree. Signed-off-by:

Pass device pointer instead of device name as parameter to iio_channel_get_all and iio_channel_get_all_cb. This will enable us to use OF information to retrieve consumer channel information. Signed-off-by:

For chips with more than 8 bit ADC resolution, received data was always masked against 0xfff, ie with a 12 bit mask. 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. Signed-off-by:

The adxrs450 is in a reasonable shape now. It follows the IIO ABI and non of the standard code checker tools report any issue, so move it out of staging. Signed-off-by:

Lars-Peter Clausen authored
The contents of the adxrs450 header file is not used outside the main drivers file, so just move the contents from the header file into the drivers main file. Also rename the adxrs450 driver file from adxrs450_core.c to adxrs450.c. Signed-off-by:

The adxrs450 requires a delay of at least 0.1 ms between register writes. Using msleep() for such small delays is not recommended. So use usleep_range instead. Fixes the following checkpatch warning: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt + msleep(1); Signed-off-by:

This is one of the exceptions to the 80 chars per line rule since breaking the string in half it badly affects the grep-ability.

This partially reverts commit cb449687. There is no apparent reason why we should split a transaction which consists out of multiple transfers into multiple transactions each having one transfer. While this works it introduces a bunch of unnecessary context switch and additional setup costs. Signed-off-by:

__iio_update_buffer updates the buffer's bytes_per_datum and length fields. But the only user of this function just passes in these exact fields, so the call basically looks like this: buffer->bytes_per_datum = buffer->bytes_per_datum; buffer->length = buffer->length; Which means it is a noop and can be removed. Also remove the function itself, since it is now unused. Signed-off-by:

Convert this pcmcia driver to the comedi auto attach mechanism. This allows getting rid of the "hack" needed to pass the pcmcia_device pointer from the pcmcia_driver to the comedi_driver. We can also get rid of the boardinfo since it was only used to provide the "name" that was used with the manual attach. Signed-off-by:

Convert this pcmcia driver to the comedi auto attach mechanism. This allows getting rid of the "hack" needed to pass the pcmcia_device pointer from the pcmcia_driver to the comedi_driver. We still need the boardinfo because the das08 driver uses it. But we can get rid of the duplicate that allowed attaching with the driver name. Signed-off-by:

Separate the comedi_pcmcia_* functions out of drivers.c into a new source file, comedi_pcmcia.c. This allows conditionally building support for comedi pcmcia drivers into the comedi core without the need for the #if'defery. Fix the Kconfig and Makefile appropriately. Group all the comedi_pcmcia_* prototypes into one place in comedidev.h. Protect these prototypes with an #ifdef so that building a comedi pcmcia driver without PCMCIA support will cause a build error. This will normally not happen as long as the comedi pcmcia driver is placed in the proper group in the Kconfig. Remove the #include <pcmcia/*.h> from drivers.c. These includes are only needed by the comedi pcmcia driver support code and the pcmcia drivers. The include should occur in those files. Signed-off-by:

Separate the comedi_pci_* functions out of drivers.c into a new source file, comedi_pci.c. This allows conditionally building support for comedi PCI drivers into the comedi core. Fix the Kconfig and Makefile appropriately. Group all the comedi_pci_* prototypes and related defines into one place in comedidev.h. Protect these prototypes with an #ifdef and provide some dummy functions so that the mixed ISA/PCI comedi drivers will still build correctly. Remove the #include <linux/pci.h> from comedidev.h and drivers.c. This include is only needed by the comedi PCI driver support code and the PCI drivers. The include should occur in those files. Also, remove the #include <linux/pci.h> from a couple non-PCI drivers since it's not needed. Signed-off-by:

Separate the comedi_usb_* functions out of drivers.c into a new source file, comedi_usb.c. This allows conditionally building support for comedi USB drivers into the comedi core without the need for the #if'defery. Fix the Kconfig and Makefile appropriately. For aesthetic reasons, add some whitespace to the Makefile to keep everything lined up. Group all the comedi_usb_* prototypes into one place in comedidev.h. Protect these prototypes with an #ifdef so that building a comedi usb driver without USB support will cause a build error. This will normally not happen as long as the comedi USB driver is placed in the proper group in the Kconfig. Remove the #include<linux/usb.h> from comedidev.h and drivers.c. This include is only needed by the comedi USB driver support code and the USB drivers. The include should occur in those files. Removing the include of usb.h exposed a couple drivers that need <linux/interrupt.h> and <linux/sched.h>. Add the missing includes. Signed-off-by:

This error happens because PIPEnsControlOut and PIPEnsControlIn unlock the spin lock for delay, letting in another thread. The patch moves the current MP_SET_FLAG to before filling of sUsbCtlRequest for pControlURB and clears it in event of failing. Any thread calling either function while fMP_CONTROL_READS or fMP_CONTROL_WRITES flags set will return STATUS_FAILURE. Signed-off-by:
