iio:ad7266: Fix probe deferral for vref

2016-07-27T16:55:51+00:00

commit 68b356eb3d9f5e38910fb62e22a78e2a18d544ae upstream. Currently the ad7266 driver treats any failure to get vref as though the regulator were not present but this means that if probe deferral is triggered the driver will act as though the regulator were not present. Instead only use the internal reference if we explicitly got -ENODEV which is what is returned for absent regulators.

iio:ad7266: Fix support for optional regulators

2016-07-27T16:55:51+00:00

commit e5511c816e5ac4909bdd38e85ac344e2b9b8e984 upstream. The ad7266 driver attempts to support deciding between the use of internal and external power supplies by checking to see if an error is returned when requesting the regulator. This doesn't work with the current code since the driver uses a normal regulator_get() which is for non-optional supplies and so assumes that if a regulator is not provided by the platform then this is a bug in the platform integration and so substitutes a dummy regulator. Use regulator_get_optional() instead which indicates to the framework that the regulator may be absent and provides a dummy regulator instead.

iio:ad7266: Fix broken regulator error handling

2016-07-27T16:55:50+00:00

commit 6b7f4e25f3309f106a5c7ff42c8231494cf285d3 upstream. All regulator_get() variants return either a pointer to a regulator or an ERR_PTR() so testing for NULL makes no sense and may lead to bugs if we use NULL as a valid regulator. Fix this by using IS_ERR() as expected. Signed-off-by: Mark Brown Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio:ad7793: Fix ad7785 product ID

2016-02-25T19:58:53+00:00

commit 785171fd6cd7dcd7ada5a733b6a2d44ec566c3a0 upstream. While the datasheet for the AD7785 lists 0xXB as the product ID the actual product ID is 0xX3. Fix the product ID otherwise the driver will reject the device due to non matching IDs.

iio: adc: at91_adc: allow to use full range of startup time

2015-08-03T16:29:53+00:00

commit 2ab5f39bc7825808e0fa1e7e5f0b23e174563467 upstream. The DT-Property "atmel,adc-startup-time" is stored in an u8 for a microsecond value. When trying to increase the value of STARTUP in Register AT91_ADC_MR some higher values can't be reached. Change the type in function parameter and private structure field from u8 to u32.

iio:adc:mcp3422 Fix incorrect scales table

2015-03-18T12:31:26+00:00

commit 9e128ced3851d2802b6db870f6b2e93f449ce013 upstream. This patch fixes uncorrect order of mcp3422_scales table, the values was erroneously transposed. It removes also an unused array and a wrong comment. Signed-off-by: Angelo Compagnucci Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

commit 9e5846be33277802c0c76e5c12825d0e4d27f639 upstream. This can result in wrong reference count for trigger device, call iio_trigger_get to increment reference.

iio: ti_am335x_adc: Fix: Use same step id at FIFOs both ends

2014-07-17T23:21:02+00:00

commit baa3c65298c089a9014b4e523a14ec2885cca1bc upstream. Since AI lines could be selected at will (linux-3.11) the sending and receiving ends of the FIFO does not agree about what step is used for a line. It only works if the last lines are used, like 5,6,7, and fails if ie 2,4,6 is selected in DT.

iio: adc: at91: signedness bug in at91_adc_get_trigger_value_by_name()

commit 4f3bcd878f1d3c730fe00f619b7260c6125d49eb upstream. at91_adc_get_trigger_value_by_name() was returning -ENOMEM truncated to a positive u8 and that doesn't work. I've changed it to int and refactored it to preserve the error code.
