iio: resolver: ad2s1210: add missing select (TRIGGERED_)BUFFER in Kconfig

2024-10-06T15:30:38+00:00

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'.

iio: resolver: ad2s1210 add missing select REGMAP in Kconfig

2024-10-06T15:30:27+00:00

This driver makes use of regmap, but does not select the required module. Add the missing 'select REGMAP'.

iio: resolver: ad2s1210: add reset gpio support

2023-11-16T19:10:25+00:00

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.

iio: resolver: ad2s1210: add support for adi,fixed-mode

2023-11-16T19:10:25+00:00

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.

iio: resolver: ad2s1210: remove of_match_ptr()

2023-10-14T12:53:45+00:00

To be consistent with the rest of iio, remove of_match_ptr(). It does not do anything useful here. Suggested-by: Jonathan Cameron Signed-off-by: David Lechner Link: https://lore.kernel.org/r/20231012-ad2s1210-mainline-v1-2-b2ee31c0e9dd@baylibre.com Signed-off-by: Jonathan Cameron

iio: resolver: ad2s1210: remove DRV_NAME macro

2023-10-14T12:53:45+00:00

The DRV_NAME macro is only used in one place in the ad2s1210 driver and is not really needed so let's remove it. Suggested-by: Jonathan Cameron Signed-off-by: David Lechner Link: https://lore.kernel.org/r/20231012-ad2s1210-mainline-v1-1-b2ee31c0e9dd@baylibre.com Signed-off-by: Jonathan Cameron

iio: resolver: ad2s1210: move out of staging

This moves the ad2s1210 resolver driver out of staging. The driver has been fixed up and is ready to graduate. Signed-off-by: David Lechner Link: https://lore.kernel.org/r/20231010-ad2s1210-mainline-v5-4-35a0f6ffa04a@baylibre.com Signed-off-by: Jonathan Cameron

iio: resolver: ad2s90: Fix alignment for DMA safety

2022-06-14T10:53:19+00:00

____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.

iio:resolver:ad2s1200: Drop of_match_ptr protection

2020-09-21T17:41:31+00:00

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. Signed-off-by: Jonathan Cameron Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20200910173242.621168-24-jic23@kernel.org
