2018-02-18iio: add SPDX identifier for various driversMatt Ranostay1-13/+4
Add GPLv2+ SPDX identifier and update email for author's drivers. Signed-off-by: Matt Ranostay <matt.ranostay@konsulko.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2017-08-22iio:chemical: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-1/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-03-30drivers: iio: chemical: replace comma with a semicolonArushi Singhal1-1/+1
Replace a comma between expression statements by a semicolon. This changes the semantics of the code, but given the current indentation appears to be what is intended. A simplified version of the Coccinelle semantic patch that performs this transformation is as follows: // <smpl> @r@ expression e1,e2; @@ e1 -, +; e2; // </smpl> Signed-off-by: Arushi Singhal <arushisinghal19971997@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

drivers/iio/chemical/vz89x.c:119:9-10: WARNING: return of 0/1 in function 'vz89x_measurement_is_valid' with return type bool Return statements in functions returning bool should use true/false instead of 1/0.

2016-08-29iio: chemical: vz89x: prevent corrupted buffer from being readMatt Ranostay1-2/+6
Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-08-29iio: chemical: vz89x: add support for VZ89TE partMatt Ranostay1-15/+98
Add support the VZ89TE variant which removes the voc_short channel, and has CRC check for data transactions. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-08-29iio: chemical: vz89x: abstract chip configurationMatt Ranostay1-18/+62
Abstract chip configuration data to allow supporting multiple variants of the VZ89 chemical sensor line. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-02-27iio: convert to common i2c_check_functionality() return valueMatt Ranostay1-1/+1
Previously most drivers that used a i2c_check_functionality() check condition required various error codes on failure. This patchset converts to a standard of -EOPNOTSUPP Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-12-03iio: chemical: vz89x: rework i2c transfer readingMatt Ranostay1-14/+52
Add an optimized i2c transfer reading function, and fallback to racey smbus transfers if client->adapter doesn't support this. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2015-09-30iio: chemical: vz89x hardware i2c workaroundMatt Ranostay1-2/+21
Chipset sometime updates in the middle of a reading causing it to reset the data pointer, and causing invalid reading of previous data. We can check for this invalid state by reading MSB of the resistance reading that is always zero, and by also confirming the VOC_short isn't zero.

2015-09-23iio: chemical: add SGX VZ89x VOC sensor supportMatt Ranostay1-0/+237
Add support for VZ89X sensors VOC and CO2 reporting channels in percentage which can be converted to part per million. Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
