iio: dac: ad5770r: make ad5770r_rng_tbl const

2025-07-06T09:37:53Z

Add const qualifier to struct ad5770r_output_modes ad5770r_rng_tbl[]. This is read-only data so it can be made const. Signed-off-by: David Lechner Link: https://patch.msgid.link/20250628-iio-const-data-15-v1-1-b86ae055004c@baylibre.com Signed-off-by: Jonathan Cameron

iio: normalize array sentinel style

2025-04-22T18:10:04Z

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.

iio: dac: ad5770r: Use device_for_each_child_node_scoped()

2024-04-06T10:18:51Z

Switching to the _scoped() version removes the need for manual calling of fwnode_handle_put() in the paths where the code exits the loop early. In this case that's all in error paths.

iio: dac: ad5770r: Fix alignment for DMA safety

2022-06-14T10:53:16Z

____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1. Switch to the updated IIO_DMA_MINALIGN definition.

iio: ad5770r: make devicetree property reading consistent

2021-09-14T11:00:32Z

The bindings file for this driver is defining the property as 'reg' but the driver was reading it with the 'num' name. The bindings actually had the 'num' property when added in commit ea52c21268e6 ("dt-bindings: iio: dac: Add docs for AD5770R DAC") and then changed it to 'reg' in commit 2cf3818f18b2 ("dt-bindings: iio: dac: AD5570R fix bindings errors"). However, both these commits landed in v5.7 so the assumption is that either 'num' is not being used or if it is, the validations were not done. Anyways, if someone comes back yelling about this, we might just support both of the properties in the future. Not ideal, but that's life...

device_for_each_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller.

iio: dac: Convert powerdown read callbacks to sysfs_emit()

2021-03-29T10:12:30Z

Update DAC drivers powerdown attribute show callback to use the new sysfs_emit() function. sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in sanity checks.
