2019-01-05staging: iio: adc: ad7606: Move out of stagingStefan Popa1-82/+0
Move ad7606 ADC driver out of staging and into the mainline. Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-01-05staging: iio: adc: ad7606: Misc style fixes (no functional change)Stefan Popa1-8/+8
* Placed includes in alphabetical order * Added brackets around num and mask through out for AD760X_CHANNEL * Used single line comments where needed * Removed extra lines and spaces Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-01-05staging: iio: adc: ad7606: Use SPDX identifierStefan Popa1-2/+1
This patch replaces the license text at the top of ad7606 driver files and instead adds SPDX GPL-2.0 license identifier. Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-12-22staging: iio: adc: ad7606: Add OF device ID tableStefan Popa1-0/+10
The driver does not have a struct of_device_id table, but supported devices are registered via Device Trees. This patch adds and OF device ID table. Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-12-22staging: iio: adc: ad7606: Use devm functions in probeStefan Popa1-6/+0
Switch to devm version of request_irq, iio_triggered_buffer_setup, iio_device_register. To avoid potential ordering issues in probe, devm_add_action_or_reset() is used for the regulator_disable(). This simplifies the code and decreases the chance of bugs. Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-09-22staging:iio:ad7606: Add support for the ad7605-4Alexandru Ardelean1-0/+1
Add support for the AD7605-4 to the AD7606 driver. The AD7605-4 is mostly interface compatible to the AD7606-6 with the only difference being not having support for oversampling.

2016-10-23staging:iio:ad7606: Let common remove function take a struct device *Lars-Peter Clausen1-3/+1
Currently the common remove function takes a struct iio_dev *. This parameter is retrieved by the individual driver remove functions by calling get_drvdata() on their device. To simplify the code let the common remove function directly take a struct dev * and do the IIO device in retrieval the common remove function. This also aligns the interface with the common probe function. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-10-23staging:iio:ad7606: Let the common probe function return intLars-Peter Clausen1-9/+3
The common probe function for the ad7606 currently returns a struct iio_dev pointer. The returned value is not used by the individual driver probe functions other than for error checking. Let the common probe function return a int instead to report the error value directly (or 0 on success). This allows to simplify the code.

2016-10-23staging:iio:ad7606: Move set_drvdata() into common codeLars-Peter Clausen1-2/+0
Both the platform_device and SPI driver call set_drvdata() at the end of their probe function. Move this into the common probe() function to reduce duplicated code. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-10-23staging:iio:ad7606: Remove redundant name field from ad7606_chip_infoLars-Peter Clausen1-1/+2
The name field in the ad7606_chip_info struct is set to the same value as the as the name field in the corresponding {platform,spi}_device_id table entry. Remove it from the ad7606_chip_info struct and pass the name from the ID to the probe function. This slightly reduces the size of the chip_info table and adding new entries requires less boilerplate.

2016-06-11staging: iio: fix ad7606_spi regressionArnd Bergmann1-1/+1
As pointed out by Geert Uytterhoeven, the patch was incorrect and breaks the driver, which was fortunately pointed out by this gcc warning: drivers/staging/iio/adc/ad7606_spi.c: In function ‘ad7606_spi_read_block’: drivers/staging/iio/adc/ad7606_spi.c:34: warning: ‘data’ is used uninitialized in this function The effect of the patch is that the data is copied into a random memory location (from the uninitialized pointer) instead of being byteswapped in place. This adds the initialization for the 'data' variable back to restore the original behavior.

2011-12-08staging:iio: Remove redundant spi driver bus initializationLars-Peter Clausen1-1/+0

2011-11-26staging:iio: Add missing MODULE_DEVICE_TABLE and MODULE_ALIASLars-Peter Clausen1-1/+1
Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only provide a MODULE_ALIAS while they have support for multiple device ids. This prevents auto module loading from working correctly. This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and MODULE_ALIAS'.
