2022-04-10iio: core: Enhance the kernel doc of modes and currentmodes iio_dev entriesMiquel Raynal
Let's provide more details about these two variables because their understanding may not be straightforward for someone not used to the IIO subsystem internal logic. The different modes will soon be also be more documented for the same reason.

To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1].

2022-04-04iio: adc: ad_sigma_delta: Add sequencer supportLars-Peter Clausen
Some sigma-delta chips support sampling of multiple channels in continuous mode. When the operating with more than one channel enabled, the channel sequencer cycles through the enabled channels in sequential order, from first channel to the last one. If a channel is disabled, it is skipped by the sequencer. If more than one channel is used in continuous mode, instruct the device to append the status to the SPI transfer (1 extra byte) every time we receive a sample. All sigma-delta chips possessing a sampling sequencer have this ability. Inside the status register there will be the number of the converted channel. In this way, even if the CPU won't keep up with the sampling rate, it won't send to userspace wrong channel samples. When multiple channels are enabled in continuous mode, the device needs to perform a measurement on all slots before we can push to userspace the sample. If, during sequencing and data reading, a channel measurement is lost, a desync occurred. In this case, ad_sigma_delta drops the incomplete sample and waits for the device to send the measurement on the first active slot.

Convert the module to be property provider agnostic and allow it to be used on non-OF platforms. The conversion slightly changes the logic behind property reading for the configuration values. Original code allocates just as much memory as needed. Then for each separate 32- or 64-bit value it reads it from the property and converts to a raw one which will be fed to the sensor. In the new code we allocate the amount of memory needed to retrieve all values at once from the property and then convert them as required.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: "A set of x86 fixes and updates: - Make the prctl() for enabling dynamic XSTATE components correct so it adds the newly requested feature to the permission bitmap instead of overwriting it. Add a selftest which validates that. - Unroll string MMIO for encrypted SEV guests as the hypervisor cannot emulate it. - Handle supervisor states correctly in the FPU/XSTATE code so it takes the feature set of the fpstate buffer into account. The feature sets can differ between host and guest buffers. Guest buffers do not contain supervisor states. So far this was not an issue, but with enabling PASID it needs to be handled in the buffer offset calculation and in the permission bitmaps. - Avoid a gazillion of repeated CPUID invocations in by caching the values early in the FPU/XSTATE code. - Enable CONFIG_WERROR in x86 defconfig. - Make the X86 defconfigs more useful by adapting them to Y2022 reality" * tag 'x86-urgent-2022-04-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu/xstate: Consolidate size calculations x86/fpu/xstate: Handle supervisor states in XSTATE permissions x86/fpu/xsave: Handle compacted offsets correctly with supervisor states x86/fpu: Cache xfeature flags from CPUID x86/fpu/xsave: Initialize offset/size cache early x86/fpu: Remove unused supervisor only offsets x86/fpu: Remove redundant XCOMP_BV initialization x86/sev: Unroll string mmio with CC_ATTR_GUEST_UNROLL_STRING_IO x86/config: Make the x86 defconfigs a bit more usable x86/defconfig: Enable WERROR selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM test x86/fpu/xstate: Fix the ARCH_REQ_XCOMP_PERM implementation

2022-04-02Revert "clk: Drop the rate range on clk_put()"Stephen Boyd
This reverts commit 7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are multiple reports that this breaks boot on various systems. The common theme is that orphan clks are having rates set on them when that isn't expected. Let's revert it out for now so that -rc1 boots.

This log message was accidentally chopped off. I was wondering why this happened, but checking the ML log, Mark precisely followed my suggestion [1]. I just used "..." because I was too lazy to type the sentence fully. Sorry for the confusion.
