iio: cros: Register FIFO callback after sensor is registered

2022-08-17T13:15:35Z

[ Upstream commit 0b4ae3f6d1210c11f9baf159009c7227eacf90f2 ] Instead of registering callback to process sensor events right at initialization time, wait for the sensor to be register in the iio subsystem. Events can come at probe time (in case the kernel rebooted abruptly without switching the sensor off for instance), and be sent to IIO core before the sensor is fully registered.

iio: core: Fix IIO_ALIGN and rename as it was not sufficiently large

2022-08-17T13:15:08Z

[ Upstream commit 12c4efe3509b8018e76ea3ebda8227cb53bf5887 ] 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.

iio: accel: bma400: conversion to device-managed function

2022-08-17T13:15:07Z

[ Upstream commit 12c99f859fd3da5fc8f8491826e7023001f54821 ] This is a conversion to device-managed by using devm_iio_device_register() inside probe function. Previously the bma400 was not put into power down mode in some error paths in probe where it now is, but that should cause no harm. The dev_set_drvdata() call, bma400_remove() function and hooks in the I2C and SPI driver struct is removed as devm_iio_device_register() function is used to automatically unregister on driver detach.
