iio: imu: mpu6050: Fix alignment for DMA safety

2022-08-17T13:15:18Z

[ Upstream commit 54e03562bb960e78af050d2e550c28d77642ee44 ] ____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1.

2022-06-19T16:22:49Z

The 0 value used for INV_CHIP_ICM42600 was not working since the match in i2c/spi was checking against NULL value. To keep this check, add a first INV_CHIP_INVALID 0 value as safe guard.

iio: imu: adis16480: Improve getting the optional clocks

2022-04-28T18:22:56Z

The extended clocks are optional and may not be present for some configurations supported by this driver. Nevertheless, in case the clock is provided but some error happens during its getting, that error handling should be done properly. Use devm_clk_get_optional() API and report possible errors using dev_err_probe() to handle properly -EPROBE_DEFER error.
