2018-11-07staging: comedi: addi_apci_3501: Use insn->n in EEPROM insn_read handlerIan Abbott
The `insn_read` handler for the EEPROM subdevice (`apci3501_eeprom_insn_read()`) currently ignores `insn->n` (the number of samples to be read) and assumes a single sample is to be read. But `insn->n` could be 0, meaning no samples should be read, in which case `data[0]` ought not to be written. (The comedi core at least ensures that `data[0]` exists, but we should not rely on that.) Following the usual Comedi guidelines and interpret `insn->n` as the number of samples to be read, but only read the EEPROM location once and make `insn->n` copies, as we don't expect the contents of the EEPROM location to change between readings.

2017-11-28staging: comedi: drivers: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all comedi files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-28staging: comedi: add SPDX identifiers to all greybus driver filesGreg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/staging/comedi files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2016-08-21staging: comedi: addi_apci_3501: remove timer/counter subdevice supportH Hartley Sweeten
This driver is for a simple 4/8 channel analog output board with 2 isolated digital inputs and 2 isolated digital outputs. Support for these subdevices is provided by the driver. The boards also has a watchdog timer that can be used to reset the analog outputs. It can also be used as a general purpose 12-bit timer when the watchdog function is not necessary. The current support code for this subdevice is broken. It does not follow the comedi API and requires some out-of-tree patches in order to even work. Remove the subdevice support. If a proper register map can be located for this board we can add support back later.

This function works similar to comedi_legacy_detach() where it will: * free the dev->irq if it has been requested * iounmap the dev->mmio addres if it has been ioremap'ed The helper then calls comedi_pci_disable() to release the regions and disable the PCI device. Use the new helper directly for the (*detach) in the following cases: * where comedi_pci_disable() is used directly for the (*detach) * where the detach function is just boilerplate Use the new helper in the (*detach) of the simpler PCI drivers. Call the helper after disabling interrupts (reset) and before any additional cleanup (kfree) to avoid any race conditions with the interrupt handler.

2013-01-25staging: comedi: addi_apci_3501: rewrite the analog output supportH Hartley Sweeten
Currently the analog output subdevice has two support functions: (*insn_config) - i_APCI3501_ConfigAnalogOutput() (*insn_write) - i_APCI3501_WriteAnalogOutput() The (*insn_config) function is used to configure the analog outputs in either bipolar or unipolar mode. This function abuses the comedi API since it treats the data[0] value as a parameter instead of as the config "instruction". The (*insn_write) function then writes a single value to the desired analog output channel after doing some sanity checking on the channel number. The sanity checking is not required since the comedi core has already done it. Also, the (*insn_write) functions are supposed to write all the data, indicated by insn->n, to the channel not just a single value. Rewrite the support code so it works properly with the comedi API. The bipolar/unipolar configuration can be determine in the (*insn_write) by checking the passed insn->chanspec. Since the unipolar configuration only has 13-bit resolution, we need to check that the data is in range because the subdevice 'maxdata' is set to 14-bits for the bipolar mode. If the data is out of range, output a dev_warn() and return -EINVAL.

2013-01-25staging: comedi: addi_apci_3501: only allocate needed subdevicesH Hartley Sweeten
The addi-data "common" code always allocated 7 subdevices. This driver only uses 5. Change the allocation and remove the unused subdevices.

2013-01-25staging: comedi: addi_apci_3501: remove boardinfoH Hartley Sweeten
With the eeprom support code now local to this driver, we can remove the boardinfo since it's not necessary. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-25staging: comedi: addi_apci_3501: simplify reading the eepromH Hartley Sweeten
The only value in the eeprom that is used by this driver is the number of analog output channels. Copy the necessary code from addi_eeprom.c to this driver and refactor it so that we can get the value needed.

2013-01-25staging: comedi: addi_apci_3501: board has an eepromH Hartley Sweeten
The board supported by this driver has an on-board eeprom. Since we need to read it to get the number of analog output channels, expose the eeprom as a readable subdevice to the user. Rename the i_ADDIDATA_InsnReadEeprom() function to give it namespace associated with the driver.
