74128d801b watchdog: ux500_wdt: Drop platform data
Drop the platform data passing from the PRCMU driver. This platform
data was part of the ambition to support more SoCs, which in turn
were never mass produced.

Only a name remains of the MFD cell so switch to MFD_CELL_NAME().

platform/chrome: cros_ec_proto: Use EC struct for features
The Chrome EC's features are returned through an
ec_response_get_features struct, but they are stored in an independent
array. Although the two are effectively the same at present (2 unsigned
32 bit ints), there is the possibility that they could go out of sync.
Avoid this by only using the EC struct to store the features.

90fc6ff48b mfd: ti_am335x_tscadc: Support the correctly spelled DT property
There was in the past a typo in the coordinate readouts property. The
bindings have been updated, the touchscreen driver as well and now
supports both. However, the MFD driver that is in charge of verifying
the validity of the property only checks the bogus one. Add support for
the correctly spelled DT property.

bf0f394c7b mfd: ti_am335x_tscadc: Introduce a helper to deal with the type of hardware
One way of knowing which hardware we are dealing with is to check the
compatible string. When this must be done at several places, it's best
and certainly more clear to use a helper for that.

Introduce ti_adc_with_touchscreen() to indicate if there is a touchscreen
controller available (meaning it's an am33xx-like ADC). This helper does
not indicate if it is actually used (that is the purpose of the use_tsc
boolean).

Introducing this helper helps making a difference in the code between
what is generic to both types of ADCs and what is specific to the am33xx
hardware before introducing support for the am437x hardware.

3dafbe93be mfd: ti_am335x_tscadc: Reorder the initialization steps
TI AM335X TRM [1] states that most of the configuration should be set in
the control register in the first place, before actually enabling the
hardware with the subsystem enable bit.

So far only half of the configuration was made in the first step (before
enabling the "subsystem"), which does not make really sense. Also, the
probe and the resume patch were acting differently. Let's harmonize all
this by following these steps:
1/ Configure the CLKDIV register
2/ Configure the CTRL register
3/ Configure the idle configuration
4/ Really enable the device by rewriting the CTRL register with the
   subsystem enable bit set.

75d6e7d9ce Nothing changed in the clk framework core this time around. We did get
some updates to the basic clk types to use determine_rate for the
 divider type and add a power of two fractional divider flag though.
 Otherwise, this is a collection of clk driver updates. More than half
 the diffstat is in the Qualcomm clk driver where we add a bunch of data
 to describe clks on various SoCs and fix bugs. The other big new thing
 in here is the Mediatek MT8192 clk driver. That's been under review for
 a while and it's nice to see that it's finally upstream.
 
 Beyond that it's the usual set of minor fixes and tweaks to clk drivers.
 There are some non-clk driver bits in here which have all been acked by
 the respective maintainers.
 
 New Drivers:
  - Support video, gpu, display clks on qcom sc7280 SoCs
  - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs
  - Multimedia clks (MMCC) on qcom MSM8994/MSM8992
  - RPMh clks on qcom SM6350 SoCs
  - Support for Mediatek MT8192 SoCs
  - Add display (DU and DSI) clocks on Renesas R-Car V3U
  - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and
    resets on Renesas RZ/G2L
 
 Updates:
  - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators
  - Add power of two flag to fractional divider clk type
  - Migrate some clk drivers to clk_divider_ops.determine_rate
  - Migrate to clk_parent_data in gcc-sdm660
  - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2
  - Switch from .round_rate to .determine_rate in clk-divider-gate
  - Fix clock tree update for TF-A controlled clocks for all i.MX8M
  - Add missing M7 core clock for i.MX8MN
  - YAML conversion of rk3399 clock controller binding
  - Removal of GRF dependency for the rk3328/rk3036 pll types
  - Drop CLK_IS_CRITICAL flag from Tegra fuse clk
  - Make CLK_R9A06G032 Kconfig symbol invisible
  - Convert various DT bindings to YAML

ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e890605 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,

c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

a946506c48 mfd: tqmx86: Clear GPIO IRQ resource when no IRQ is set
The driver was registering IRQ 0 when no IRQ was set. This leads to
warnings with newer kernels.

Clear the resource flags, so no resource is registered at all in this
case.

c753ea3178 mfd: simple-mfd-i2c: Add support for registering devices via MFD cells
More devices are cropping up requiring only Regmap initialisation and
child registration functionality.  We currently only support that if
all required devices are represented by their own Device Tree nodes
complete with compatible strings.

However, not everyone is happy with adding empty nodes that provide no
additional device information into the Device Tree.

Rather than have a plethora of mostly empty, function-less drivers in
MFD, we'll support those simple cases in here instead via MFD cells.

f28fd3b6f7 mfd/cpuidle: ux500: Rename driver symbol
The PRCMU driver defines this as a DT node but there are no bindings
for it and it needs no data from the device tree. Just spawn the
device directly in the same way as the watchdog.

Name it "db8500-cpuidle" since there are no ambitions to support any
more SoCs than this one.

This rids this annoying boot message:
[    0.032610] cpuidle-dbx500: Failed to locate of_node [id: 0]

However I think the device still spawns and work just fine, despite
not finding a device tree node.

72b89b9ab5 mfd: tps65086: Add cell entry for reset driver
The only way to reset the BeagleV Starlight v0.9 board[1] properly is to
tell the PMIC to reset itself which will then assert the external reset
lines of the SoC, USB hub and ethernet phy.

This adds an mfd cell entry for the reset driver doing just that.

The BeagleV Starlight v0.9 board[1] doesn't have the IRQB line routed to
the SoC, but it is still useful to be able to reach the PMIC over I2C
for the other functionality it provides such as GPIOs and regulator
settings.

The driver can provide a software node group instead of
passing legacy platform data. This will allow to drop
the legacy platform data structures along with unifying
a child device driver to use same interface for all
property providers, i.e. Device Tree, ACPI, and board files.
