2021-05-17iio: adis: add burst_max_speed_hz variableNuno Sa2-0/+6
Typically, in burst mode, the device cannot operate at it's full spi speed. Hence, the spi transfers for burst mode have to take this into account. With this change we avoid a potential race with the spi core as drivers were 'hacking' the device 'max_speed_hz' directly in the trigger handler.

It makes more sense to update the device page as soon as we we successfully changed it. Moreover, a follow up patch will handle 'spi_sync' error path which would leave 'current_page' in a inconsistent state.

2021-05-17iio: adis16475: do not return ints in irq handlersNuno Sa1-1/+1
On an IRQ handler we should not return normal error codes as 'irqreturn_t' is expected. This is done by jumping to the 'check_burst32' label where we return 'IRQ_HANDLED'. Note that it is fine to do the burst32 check in this error path. If we have proper settings to apply burst32, we might just do the setup now so that the next sample already uses it.

This binding covers class of simple SPI ADCs which only provide data output - they don't have MOSI pin. The only real variation between them is over how many supplies they use and which one is used for the reference. Michael listed as maintainer for this one as it is his driver and falls under the catch all MAINTAINERS entry for ADI devices.

2021-05-17iio:adc:ad7476: Handle the different regulators used by various parts.Jonathan Cameron1-15/+103
Not all of the parts supported by this driver use single supply. Hence we add chip_info fields to say what additional supplies exist and in the case of vref, ensure that is used for the reference voltage rather than vcc. One corner case is the ad7091r which has an internal reference that can be over-driven by an external reference connected on the vref pin. To handle that force_ext_vref is introduced and set if an optional vref regulator is present. Tested using really simple QEMU model and some fixed regulators. The devm_add_action_or_reset() callback is changed to take the regulator as it's parameter so we can use one callback for all the different regulators without having to store pointers to them in the iio_priv() structure.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer fixes from Thomas Gleixner: "Two fixes for timers: - Use the ALARM feature check in the alarmtimer core code insted of the old method of checking for the set_alarm() callback. Drivers can have that callback set but the feature bit cleared. If such a RTC device is selected then alarms wont work. - Use a proper define to let the preprocessor check whether Hyper-V VDSO clocksource should be active. The code used a constant in an enum with #ifdef, which evaluates to always false and disabled the clocksource for VDSO" * tag 'timers-urgent-2021-05-16' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource/drivers/hyper-v: Re-enable VDSO_CLOCKMODE_HVCLOCK on X86 alarmtimer: Check RTC features instead of ops

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Borislav Petkov: "The three SEV commits are not really urgent material. But we figured since getting them in now will avoid a huge amount of conflicts between future SEV changes touching tip, the kvm and probably other trees, sending them to you now would be best. The idea is that the tip, kvm etc branches for 5.14 will all base ontop of -rc2 and thus everything will be peachy. What is more, those changes are purely mechanical and defines movement so they should be fine to go now (famous last words). Summary: - Enable -Wundef for the compressed kernel build stage - Reorganize SEV code to streamline and simplify future development" * tag 'x86_urgent_for_v5.13_rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/compressed: Enable -Wundef x86/msr: Rename MSR_K8_SYSCFG to MSR_AMD64_SYSCFG x86/sev: Move GHCB MSR protocol and NAE definitions in a common header x86/sev-es: Rename sev-es.{ch} to sev.{ch}

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix a regression in the conversion of the 64-bit BookE interrupt entry to C. - Fix KVM hosts running with the hash MMU since the recent KVM gfn changes. - Fix a deadlock in our paravirt spinlocks when hcall tracing is enabled. - Several fixes for oopses in our runtime code patching for security mitigations. - A couple of minor fixes for the recent conversion of 32-bit interrupt entry/exit to C. - Fix __get_user() causing spurious crashes in sigreturn due to a bad inline asm constraint, spotted with GCC 11. - A fix for the way we track IRQ masking state vs NMI interrupts when using the new scv system call entry path. - A couple more minor fixes.
