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.

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"

- Remove support for PowerPC 601.
- Some fixes for watchpoints & addition of a new ptrace flag for detecting ISA v3.1 (Power10) watchpoint features.
- A fix for kernels using 4K pages and the hash MMU on bare metal Power9 systems with > 16TB of RAM, or RAM on the 2nd node.
- A basic idle driver for shallow stop states on Power10.
- Tweaks to our sched domains code to better inform the scheduler about the hardware topology on Power9/10, where two SMT4 cores can be presented by firmware as an SMT8 core.
- A series doing further reworks & cleanups of our EEH code.
- Addition of a filter for RTAS (firmware) calls done via sys_rtas(), to prevent root from overwriting kernel memory.
- Other smaller features, fixes & cleanups.

powerpc/hv-gpci: Add sysfs files inside hv-gpci device to show cpumask
Patch here adds a cpumask attr to hv_gpci pmu along with ABI documentation.
Primary use to expose the cpumask is for the perf tool which has the capability to parse the driver sysfs folder and understand the cpumask file. Having cpumask file will reduce the number of perf command line parameters (will avoid "-C" option in the perf tool command line). It can also notify the user which is the current cpu used to retrieve the counter data.
