* iio: adc: ad7887: Fix alignment for DMA safetyJonathan Cameron2022-06-141-3/+2
| | | | | | | | | | | | | | | | | ____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. Update the comment to include 'may'. Fixes tag is clearly not where this was introduced but it is very unlikely anyone will back port it past that point.

* iio: core: Fix IIO_ALIGN and rename as it was not sufficiently largeJonathan Cameron2022-06-143-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Discussion of the series: https://lore.kernel.org/all/20220405135758.774016-1-catalin.marinas@arm.com/ mm, arm64: Reduce ARCH_KMALLOC_MINALIGN brought to my attention that our current IIO usage of L1CACHE_ALIGN is insufficient as their are Arm platforms out their with non coherent DMA and larger cache lines at at higher levels of their cache hierarchy. Rename the define to make it's purpose more explicit. It will be used much more widely going forwards (to replace incorrect ____cacheline_aligned markings. Note this patch will greatly reduce the padding on some architectures that have smaller requirements for DMA safe buffers. The history of changing values of ARCH_KMALLOC_MINALIGN via ARCH_DMA_MINALIGN on arm64 is rather complex. I'm not tagging this as fixing a particular patch from that route as it's not clear what to tag. Most recently a change to bring them back inline was reverted because of some Qualcomm Kryo cores with an L2 cache with 128-byte lines sitting above the point of coherency. c1132702c71f Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)" That reverts: 65688d2a05de arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES) which refers to the change originally being motivated by Thunder x1 performance rather than correctness.
