iio: light: bh1780: fix PM runtime leak on error path

2026-03-19T15:15:30+00:00

commit dd72e6c3cdea05cad24e99710939086f7a113fb5 upstream. Move pm_runtime_put_autosuspend() before the error check to ensure the PM runtime reference count is always decremented after pm_runtime_get_sync(), regardless of whether the read operation succeeds or fails.

iio: Use IRQF_NO_THREAD

2026-03-04T12:20:43+00:00

[ Upstream commit 04d390af97f2c28166f7ddfe1a6bda622e3a4766 ] The interrupt handler iio_trigger_generic_data_rdy_poll() will invoke other interrupt handler and this supposed to happen from within the hardirq. Use IRQF_NO_THREAD to forbid forced-threading. Signed-off-by: Sebastian Andrzej Siewior Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron Signed-off-by: Sasha Levin

iio: light: apds9960: convert to use maple tree register cache

2025-11-09T12:57:05+00:00

The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. Signed-off-by: Chu Guangqing Signed-off-by: Jonathan Cameron

iio: light: ltr390: Fix typo in variable name

2025-10-19T10:59:17+00:00

Corrected a spelling mistake in the ltr390 driver: 'recieve_buffer' was renamed to 'receive_buffer'. This improves code readibility without changing functionality. Signed-off-by: Sameeksha Sankpal Signed-off-by: Jonathan Cameron

iio: light: ltr390: Implement runtime PM support

2025-09-13T12:18:16+00:00

Implement runtime power management for the LTR390 sensor. The device autosuspends after 1s of idle time, reducing current consumption from 100 µA in active mode to 1 µA in standby mode as per the datasheet. Ensure that interrupts continue to be delivered with runtime PM. Since the LTR390 cannot be used as a wakeup source during runtime suspend, therefore increment the runtime PM refcount when enabling events and decrement it when disabling events or powering down. This prevents event loss while still allowing power savings when IRQs are unused. Signed-off-by: Akshay Jindal Signed-off-by: Jonathan Cameron

iio: light: Remove redundant pm_runtime_mark_last_busy() calls

2025-08-25T15:13:25+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

iio: light: Drop unnecessary -ENOMEM messages
