iio: proximity: as3935: Fix alignment for DMA safety

2022-08-17T13:15:19Z

[ Upstream commit 2386c0f8c5b740873a4b9126c3706601b127fe22 ] ____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: proximity: vl53l0x: Fix return value check of wait_for_completion_timeout

2022-04-28T18:22:55Z

wait_for_completion_timeout() returns unsigned long not int. It returns 0 if timed out, and positive if completed. The check for <= 0 is ambiguous and should be == 0 here indicating timeout which is the only error case.

iio:proximity:sx9324: Fix hardware gain read/write

2022-04-04T08:19:02Z

There are four possible gain values according to 'sx9324_gain_vals[]': 1, 2, 4, and 8 The values are off by one when writing and reading the register. The bits should be set according to this equation: ilog2() + 1 so that a gain of 8 is 0x4 in the register field and a gain of 4 is 0x3 in the register field, etc. Note that a gain of 0 is reserved per the datasheet. The default gain (SX9324_REG_PROX_CTRL0_GAIN_1) is also wrong. It should be 0x1 << 3, i.e. 0x8, not 0x80 which is setting the reserved bit 7. Fix this all up to properly handle the hardware gain and return errors for invalid settings.
