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. c1132702 Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)" That reverts: 65688d2a 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.

Different from SCA3300, SCL3300 can output inclination angles. Angles are formed from acceleration with following equations: ANG_X = atan2(accx , sqrt(pow(accy , 2) + pow(accz , 2))) ANG_Y = atan2(accy , sqrt(pow(accx , 2) + pow(accz , 2))) ANG_Z = atan2(accz , sqrt(pow(accx , 2) + pow(accy , 2))) The commit adds the output of the raw value, scale and scale_available of angles. New interfaces: in_incli_scale in_incli_scale_available in_incli_x_raw in_incli_y_raw in_incli_z_raw Data converted by application of scale to degrees. Signed-off-by:
