Merge series "regulator: bd718x7: support voltage scaling" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
RFC for adding a support for typical voltage scaling connection
In few occasions there has been a need to scale the voltage output from bucks on BD71837. Usually this is done when buck8 is used to power specific GPU which can utilize voltages down to 0.7V. As lowest the buck8 on BD71837 can go is 0.8V, and external connection is used to scale the voltages.
The BD71837, BD71847 and BD71850 bucks can be adjusted by pulling up the feedback pin using suitable voltage/resistors.
|---------------| | buck 8 |-------+----->Vout | | | |---------------| | | | | | +-------+--R2----+ | R1 | V FB-pull-up
This will scale the voltage as follows: - Vout_o = Vo - (Vpu - Vo)*R2/R1 - Linear_step = step_orig*(R1+R2)/R1 where: Vout_o is adjusted voltage output at vsel reg value 0 Vo is original voltage output at vsel reg value 0 Vpu is the pull-up voltage V FB-pull-up in the picture R1 and R2 are resistor values.
>From HW point of view this does not need to be limited to buck 8. This connection can be used to adjust output from any of the bucks on BD71837/47/50.
As this seems to be a 'de-facto' way to scale the voltages on BD71837 it might be a good idea to support computing the new voltage ranges for bucks based on the V-pull-up and resistor R1/R2 values given from device-tree. This allows describing the external HW connection using DT to correctly scale the voltages.
This RFC uses "rohm,feedback-pull-up-r1-ohms" and "rohm,feedback-pull-up-r2-ohms" to provide the resistor values - but these names (without the picture) might not be too descriptive. I am grateful for all suggestions as better and more descriptive names.
This patch series is an RFC because this connection feels somewhat "hacky". OTOH - when hack becomes widely used, it is less of an hack and more of a standard - and occasionally supporting HW hacks using SW may benefit us all, right? :)
The other thing some projects do is allowing the change of BD71837 buck8 voltages when buck8 is enabled. This however will introduce voltage spikes as buck8 was not originally designed for this. The specific HW platform must be evaluated to be able to tolerate these spikes. Thus this patch series does not support buck8 voltage changes when buck8 is enabled. I wonder if this should be allowed per some config option(?) I don't want to help people frying their boards... Opinions? Is there suggested way of allowing this type of features at own risk? Config or even Some #ifdef which is not listed in Kconfig? Device-tree property? If you have (good) suggestions I could add the optional (non default) DVS support for non DVS bucks on BD71837.

Conflicts: include/asm-generic/atomic-instrumented.h kernel/kprobes.c
Use the upstream atomic-instrumented.h checksum, and pick the kprobes version of kernel/kprobes.c, which effectively reverts this upstream workaround:

Since the new code *should* be fine without nesting.

Merge tag 'driver-core-5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and documentation fixes from Greg KH: "Here is one tiny debugfs change to fix up an API where the last user was successfully fixed up in 5.10-rc1 (so it couldn't be merged earlier), and a much larger Documentation/ABI/ update to the files so they can be automatically parsed by our tools.
The Documentation/ABI/ updates are just formatting issues, small ones to bring the files into parsable format, and have been acked by numerous subsystem maintainers and the documentation maintainer. I figured it was good to get this into 5.10-rc2 to help wih the merge issues that would arise if these were to stick in linux-next until 5.11-rc1.
The debugfs change has been in linux-next for a long time, and the Documentation updates only for the last linux-next release"

Pull staging/IIO driver updates from Greg KH: "Here is the large set of Staging and IIO driver patches for 5.9-rc1.
Lots of churn here, but overall the size increase in lines added is small, while adding a load of new IIO drivers.
Major things in here:
- lots and lots of IIO new drivers and frameworks added
- IIO driver fixes and updates
- lots of tiny coding style cleanups for staging drivers
- vc04_services major reworks and cleanups
We had 3 set of drivers move out of staging in this round as well:
- wilc1000 wireless driver moved out of staging
- speakup moved out of staging
- most USB driver moved out of staging
Full details are in the shortlog.
All of these have been in linux-next with no reported issues. The last few changes here were to resolve reported linux-next issues, and they seem to have resolved the problems"
