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

2014-07-17T23:23:08+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.

twl4030-madc: Request processed values in twl4030_get_madc_conversion

2014-07-09T18:21:28+00:00

commit e0326be0cded13dfc3a24cbeece1f1ae64348a0e upstream. Not setting the raw parameter in the request causes it to be randomly initialized to a value that might be different from zero or zero. This leads to values that are randomly either raw or processed, making it very difficult to make reliable use of the values.

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

2014-06-26T19:17:36+00:00

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.

iio: adc: checking for NULL instead of IS_ERR() in probe

2014-06-26T19:17:36+00:00

commit e94f62e79f7f63a68574ee5e76c19837ec12f3db upstream. mcb_request_mem() returns an ERR_PTR(), it doesn't return NULL. Fixes: 74aeac4da66f ('iio: adc: Add MEN 16z188 ADC driver') Signed-off-by: Dan Carpenter Signed-off-by: Jonathan Cameron Signed-off-by: Greg Kroah-Hartman

iio: adc: Nothing in ADC should be a bool CONFIG

2014-04-26T10:22:16+00:00

The whole IIO subsystem can be built as modules. If you make it a module then stuff marked as "Y" in the adc directory simply won't be linked in properly. The two configs that were wrong were EXYNOS_ADC and LP8788_ADC. I know for a fact that EXYNOS_ADC will work as a module. I assume LP8788_ADC will also be fine.

iio: exynos_adc: use indio_dev->dev structure to handle child nodes

2014-04-26T10:19:40+00:00

Using pdev->dev with device_for_each_child() would iterate over all of the children of the platform device and delete them. Thus, causing crashes during module unload. We should be using the indio_dev->dev structure for registering/unregistering child nodes.

Jonathan writes: First found of IIO fixes for the 3.15 cycle. * Fix the platform data support for the at91 adc driver. * A couple of related follow up patches get the support working again for at91sam9260 and at91sam9g45 as the earlier patch results in a device name change. * A default timer value in the at91 adc driver was bonkers. Make it sane. * Fix incorrect reporting of the integration time for the cm32181 light sensor * Fix a missing break in the ad2s1200 driver which would have give a false error return. * Make sure buffer scan mask queries from userspace return 0/1 rather than a fairly random value depending on their implementation of test_bit * Fix leak of the i2c client and a null pointer dereference in the cm36651 driver. * Fix a build warning on avr32 for the mxs-lradc (not exactly a critical combination - but the issue was real).
