2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra1-2/+2
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-09-30iio: adc: ltc2497: Get platform data via dev_get_platdata()Andy Shevchenko1-10/+5
Access to platform data via dev_get_platdata() getter to make code cleaner. While at it, drop duplicate NULL check that iio_map_array_register() already has.

2022-11-23iio: adc: ltc2947-core: do not use internal iio_dev lockNuno Sá1-2/+5
The iio_device lock is only meant for internal use. Hence define a device local lock to protect against concurrent accesses. While at it, properly include "mutex.h" for mutex related APIs.

2022-09-21drivers: iio: adc: ltc2497: Rename the LTC2499 iio deviceCiprian Regus1-1/+9
Set the iio device's name based on the chip used for the LTC2499 only. The most common way for IIO clients to interact with a device is to address it based on it's name. By using the dev_name() function, the name will be set based on a i2c_client's kobj name, which has the format i2c_instance-i2c_address (1-0076 for example). This is not ideal, since it makes a requirement for userspace to have knowledge about the hardware connections of the device. The name field is set to NULL for the LTC2497 and LTC2496, so that the old name can kept as it is, since changing it will result in an ABI breakage.

2022-09-21drivers: iio: adc: ltc2497: LTC2499 supportCiprian Regus1-1/+1
The LTC2499 is a 16-channel (eight differential), 24-bit, ADC with Easy Drive technology and a 2-wire, I2C interface. Implement support for the LTC2499 ADC by extending the LTC2497 driver. A new chip_info struct is added to differentiate between chip types and resolutions when reading data from the device.

2020-09-03iio: adc: ltc2497: Simplify with dev_err_probe()Krzysztof Kozlowski1-7/+3
Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value.

2020-06-14iio: remove left-over parent assignmentsAlexandru Ardelean1-1/+0
These were found by doing some shell magic: ------------ for file in $(git grep -w devm_iio_device_alloc | cut -d: -f1 | sort | uniq) ; do if grep 'parent =' $file | grep -v trig | grep -vq devm_; then echo "$file -> $(grep "parent =" $file)" fi done ----------- The output is bearable [after the semantic patch is applied]. There is a mix of trigger assignments with some iio device parent assignments that are removed via this patch. JC: A few more added via inspection of all parent = statements in drivers/iio. Some of these may just have crossed with this series, others were less obvious to scripting due to some cross file / module boundary calls.

2019-12-15iio: adc: ltc2497: split protocol independent part in a separate moduleUwe Kleine-König1-0/+243
This allows to share most of this driver for the ltc2496 driver added in the next commit that is an SPI variant of the ltc2497. Initially I named the generic part ltc249x, but wild card names are frowned upon, so the generic part is called ltc2497-core even though it's not obvious that this is then to be reused for the ltc2496 driver.
