Merge series "Support ROHM BD71815 PMIC" from Matti Vaittinen <matti.…

…vaittinen@fi.rohmeurope.com>:

Patch series introducing support for ROHM BD71815 PMIC

ROHM BD71815 is a power management IC used in some battery powered
systems. It contains regulators, GPO(s), charger + coulomb counter, RTC
and a clock gate.

All regulators can be controlled via I2C. LDO4 can additionally be set to
be enabled/disabled by a GPIO. LDO3 voltage could be selected from two
voltages written into separate VSEL reisters using GPIO but this mode is
not supported by driver. On top of that the PMIC has the typical HW
state machine which is present also on many other ROHM PMICs.

IC contains two GPOs - but one of the GPOs is marked as GND in
data-sheet. Thus the driver by default only exposes one GPO. The second
GPO can be enabled by special DT property.

RTC is almost similar to what is on BD71828. For currently used features
only the register address offset to RTC block differs.

The charger driver is not included in this series. ROHM has a charger
driver with some fuel-gauging logig written in but this is not included
here. I am working on separating the logic from HW specific driver and
supporting both BD71815 and BD71828 chargers in separate patch series.

Changelog v5:
  Regulator:
  - Added regmap helper for regulator ramp-delay and taken it in use
    (patches 13, 14, 16 - they can be just dropped if ramp-delay helper is not
    a good idea. Patch 15 implements old-fashioned ramp-delay)
  GPIO:
  - styling changes to GPIO (Mostly suggested by Andy)
  - implemented init_valid_mask (but can't count on it yet)
Changelog v4:
  - Sorted ROHM chip ID enum
  - Statcized DVS structures in regulator driver
  - Minor styling for regulator driver
  - rebased on v5.12-rc4
Changelog v3:
  - GPIO clean-up as suggested by Bartosz
  - MFD clean-up as suggested by Lee
  - clk-mode dt-binding handling in MFD driver corrected to reflect new
    property values.
  - Dropped already applied patches
  - Rebased on v5.12-rc2
Changelog v2:
  - Rebased on top of v5.11-rc3
  - Added another "preliminary patch" which fixes HW-dvs voltage
    handling (patch 1)
  - split regulator patch to two.
  - changed dt-binding patch ordering.
  regulators:
    - staticized probe
    - removed some unnecessary defines
    - updated comments
    - split rohm-regulator patch adding SNVS and supporting simple
      linear mapping into two - one adding support for mapping, other
      adding SNVS.
  GPIO:
    - removed unnecessary headers
    - clarified dev/parent->dev usage
    - removed forgotten #define DEBUG
  dt-bindings:
    - changed patch order to meet ref-dependencies
    - added missing regulator nodes
    - changed string property for clk mode to tristated
  MFD:
    - header cleanups.
  CLK:
    - fixed commit message

+Remove automatic page mapping from dma-buf importing
+----------------------------------------------------
+
+When importing dma-bufs, the dma-buf and PRIME frameworks automatically map
+imported pages into the importer's DMA area. drm_gem_prime_fd_to_handle() and
+drm_gem_prime_handle_to_fd() require that importers call dma_buf_attach()
+even if they never do actual device DMA, but only CPU access through
+dma_buf_vmap(). This is a problem for USB devices, which do not support DMA
+operations.
+
+To fix the issue, automatic page mappings should be removed from the
+buffer-sharing code. Fixing this is a bit more involved, since the import/export
+cache is also tied to &drm_gem_object.import_attach. Meanwhile we paper over
+this problem for USB devices by fishing out the USB host controller device, as
+long as that supports DMA. Otherwise importing can still needlessly fail.

-How can I tell what patches are queued up for backporting to the various stable releases?
------------------------------------------------------------------------------------------
-Normally Greg Kroah-Hartman collects stable commits himself, but for
-networking, Dave collects up patches he deems critical for the
-networking subsystem, and then hands them off to Greg.
-
-There is a patchworks queue that you can see here:
-
-  https://patchwork.kernel.org/bundle/netdev/stable/?state=*
-
-It contains the patches which Dave has selected, but not yet handed off
-to Greg.  If Greg already has the patch, then it will be here:
-
-  https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git
-
-A quick way to find whether the patch is in this stable-queue is to
-simply clone the repo, and then git grep the mainline commit ID, e.g.
-::
-
-  stable-queue$ git grep -l 284041ef21fdf2e
-  releases/3.0.84/ipv6-fix-possible-crashes-in-ip6_cork_release.patch

-I see a network patch and I think it should be backported to stable. Should I request it via stable@vger.kernel.org like the references in the kernel's Documentation/process/stable-kernel-rules.rst file say?
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-No, not for networking.  Check the stable queues as per above first
-to see if it is already queued.  If not, then send a mail to netdev,
-listing the upstream commit ID and why you think it should be a stable
-candidate.
-
-Before you jump to go do the above, do note that the normal stable rules
-in :ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`
-still apply.  So you need to explicitly indicate why it is a critical
-fix and exactly what users are impacted.  In addition, you need to
-convince yourself that you *really* think it has been overlooked,
-vs. having been considered and rejected.
-
-Generally speaking, the longer it has had a chance to "soak" in
-mainline, the better the odds that it is an OK candidate for stable.  So
-scrambling to request a commit be added the day after it appears should
-be avoided.
-
-I have created a network patch and I think it should be backported to stable. Should I add a Cc: stable@vger.kernel.org like the references in the kernel's Documentation/ directory say?
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-No.  See above answer.  In short, if you think it really belongs in
-stable, then ensure you write a decent commit log that describes who
-gets impacted by the bug fix and how it manifests itself, and when the
-bug was introduced.  If you do that properly, then the commit will get
-handled appropriately and most likely get put in the patchworks stable
-queue if it really warrants it.
-
-If you think there is some valid information relating to it being in
-stable that does *not* belong in the commit log, then use the three dash
-marker line as described in
-:ref:`Documentation/process/submitting-patches.rst <the_canonical_patch_format>`
-to temporarily embed that information into the patch that you send.
-
-Are all networking bug fixes backported to all stable releases?
+Are there special rules regarding stable submissions on netdev?
 ---------------------------------------------------------------
-Due to capacity, Dave could only take care of the backports for the
-last two stable releases. For earlier stable releases, each stable
-branch maintainer is supposed to take care of them. If you find any
-patch is missing from an earlier stable branch, please notify
-stable@vger.kernel.org with either a commit ID or a formal patch
-backported, and CC Dave and other relevant networking developers.
+While it used to be the case that netdev submissions were not supposed
+to carry explicit ``CC: stable@vger.kernel.org`` tags that is no longer
+the case today. Please follow the standard stable rules in
+:ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`,
