b8dfb3bed5 regulator: dt-bindings: qcom,rpmh: clean up example indentation
Remove a line break and increase indentation of the continuation line
to avoid having the 'regulator-allowed-modes' example be reproduced
verbatim with four-spaces indentation (instead of a tab, which is still
too little) in devicetree sources.

3078d0c3eb regulator: Add DT support for regulator-output connectors
Merge series from Zev Weiss <zev@bewilderbeest.net>:

This series adds support for userspace-controlled regulator-supplied
power outputs [2].  This is an important feature for some kinds of BMC
(baseboard management controller) systems where the BMC provides an
operator with manual control of a set of DC power outputs.

As in a broadly similar patchset that was recently almost merged [0],
this takes the approach of providing support by extending the existing
userspace-consumer regulator driver.  A couple questions about the
userspace-consumer driver came up along the way, however.

First, how (if at all) is it currently being used?  It appears the
last in-tree use of it was removed a bit over two years ago in commit
9d3239147d ("ARM: pxa: remove Compulab pxa2xx boards").  Aside from
just adding DT support I've made a couple small tweaks to the driver
in patch 3 that I hope are compatible with any current usage, but
without any extant examples to look at it's kind of hard to say.

Second, how critical is its support for controlling multiple
regulators?  (i.e. its use of regulator_bulk_data and friends instead
of a single struct regulator.)  As far as I can see every in-tree use
of it that's ever existed has used num_supplies = 1.  If it's not
important to retain, patch 1 of this series could be supplanted by one
that instead simplifies the driver slightly by removing that
functionality.

The DT binding added in patch 2 is essentially identical to one I
posted in a previous patchset that had an R-B from Rob [1], but has
had some minor rewording and been moved from the extcon subsystem to
the regulator subsystem.

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms

This series adds support for the regulators found in MT6331 and MT6332
main/companion PMICs.

Adding support to each driver in each subsystem is done in different
patch series as to avoid spamming uninteresting patches to maintainers.

08865c2150 regulator: dt-bindings: qcom,rpmh: Indicate regulator-allow-set-load dependencies
For RPMH regulators it doesn't make sense to indicate
regulator-allow-set-load without saying what modes you can switch to,
so be sure to indicate a dependency on regulator-allowed-modes.

In general this is true for any regulators that are setting modes
instead of setting a load directly, for example RPMH regulators. A
counter example would be RPM based regulators, which set a load
change directly instead of a mode change. In the RPM case
regulator-allow-set-load alone is sufficient to describe the regulator
(the regulator can change its output current, here's the new load),
but in the RPMH case what valid operating modes exist must also be
stated to properly describe the regulator (the new load is this, what
is the optimum mode for this regulator with that load, let's change to
that mode now).

With this in place devicetree validation can catch issues like this:

    /mnt/extrassd/git/linux-next/arch/arm64/boot/dts/qcom/sm8350-hdk.dtb: pm8350-rpmh-regulators: ldo5: 'regulator-allowed-modes' is a dependency of 'regulator-allow-set-load'
            From schema: /mnt/extrassd/git/linux-next/Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.yaml

Where the RPMH regulator hardware is described as being settable, but
there are no modes described to set it to!

The device bindings shouldn't put any constraints on the regulator-name
property specified in the generic bindings. This allows using arbitrary

Pull ARM driver updates from Arnd Bergmann:
 "There are minor updates to SoC specific drivers for chips by Rockchip,
  Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.

  Noteworthy driver changes include:

   - Several conversions of DT bindings to yaml format.

   - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.

   - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
     and support for more chips in the RPMh power domains and the
     soc-id.

   - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.

   - Apple M1 gains support for the on-chip NVMe controller, making it
     possible to finally use the internal disks. This also includes SoC
     drivers for their RTKit IPC and for the SART DMA address filter.

  For other subsystems that merge their drivers through the SoC tree, we
  have

   - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
     SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
     now has a cache for firmware argument structures as an
     optimization, and SCMI now supports the 3.1 version of the
     specification.

   - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI
     drivers

   - Memory controller updates for Tegra, and a few updates for other
     platforms"

Qualcomm driver updates for v5.19

This converts a wide range of Qualcomm-related DeviceTree bindings to
YAML, in order to improve our ability to validate the DeviceTree source.

The RPMh power-domain driver gains support for the modem platform SDX65,
the compute platform SC8280XP and the automotive platform SA8540p. While
LLCC gains support for SC8180X and SC8280XP and gains a
MODULE_DEVICE_TABLE() to make it functional as a module.

It adds a driver for configuring the SSC bus, providing Linux access to
the hardware blocks in the sensor subsystem.

The socinfo driver gets confusion related to MSM8974 Pro sorted out and
adds new ids for SM8540 and SC7280.

The SCM driver gains support for MSM8974.

Add missing of_node_put() in smp2p and smsm drivers.
Stop using iterator after list_for_each_entry() and define static
definitions as such, in the PDR driver.

The MT6315 PMIC dt-binding should enforce that one of the valid

Fix the typo. This not only fixes the compatible verification, but also
