2024-10-06iio: resolver: ad2s1210: add missing select (TRIGGERED_)BUFFER in KconfigJavier Carrasco1-0/+2
This driver makes use of triggered buffers, but does not select the required modules. Add the missing 'select IIO_BUFFER' and 'select IIO_TRIGGERED_BUFFER'.

2023-11-16iio: resolver: ad2s1210: add reset gpio supportDavid Lechner1-0/+12
This adds support for the optional reset gpio to the ad2s1210 resolver driver. If the gpio is present in the device tree, it is toggled during driver probe before the reset of the device initialization. As per the devicetree bindings, it is expected for the gpio to configured as active low.

2023-11-16iio: resolver: ad2s1210: add support for adi,fixed-modeDavid Lechner1-31/+119
It is possible to use the AD2S1210 with hardwired mode pins (A0 and A1). According to the devicetree bindings, in this case the adi,fixed-mode property will specify which of the 3 possible modes the mode pins are hardwired for and the gpio-modes property is not allowed. This adds support for the case where the mode pins are hardwired for config mode. In this configuration, the position and value must be read from the config register. The case of hardwired position or velocity mode is not supported as there would be no way to configure the device.

To be consistent with the rest of iio, remove of_match_ptr(). It does not do anything useful here.

The DRV_NAME macro is only used in one place in the ad2s1210 driver and is not really needed so let's remove it.

2022-06-14iio: resolver: ad2s90: Fix alignment for DMA safetyJonathan Cameron1-1/+1
____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. Fixes tag is probably not where the issue was first introduced, but is likely to be far beyond the point where anyone considers backporting this fix.

2020-09-21iio:resolver:ad2s1200: Drop of_match_ptr protectionJonathan Cameron1-1/+2
This prevents use of this driver with ACPI via PRP0001 and is an example of an anti pattern I'm trying to remove from IIO. Hence drop from this driver.

2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean2-2/+0
This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.
