e23dd95cfd spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
 beginnings of support for hardware initiated transfers which is itself
 independently useful for optimising fast paths in existing drivers.
 
 We also have a rework of the DMA mapping which allows finer grained
 decisions about DMA mapping messages and also helps remove some bodges
 that we'd had.
 
 Otherwise it's a fairly quiet release, a few new drivers and features
 for existing drivers, together with various cleanups and DT binding
 conversions.
 
 One regmap SPI fix made it's way in here too which I should probably
 have sent as a regmap fix instead.
 
  - Support for pre-optimising messages, reducing the overhead for
    messages that are repeatedly used (eg, reading the interrupt status
    from a device).  This will also be used for hardware initiated
    transfers in future.
  - A reworking of how DMA mapping is done, introducing a new helper and
    allowing the DMA mapping decision to be done per transfer instead of
    per message.
  - Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

c6e63a9882 pwm: Changes for v6.11-rc1
This contains the usual mix of fixes, cleanups, two new drivers and
 several dt binding updates. The fixes are for minor issues that are
 already old (4.11-rc1 and 3.9-rc1) and were found by code review and not
 during usage, so I didn't sent them for earlier inclusion.
 
 The changes to include/linux/mfd/stm32-timers.h and
 drivers/counter/stm32-timer-cnt.c are part of an immutable branch that
 will also be included in the mfd and counter PR. It changes some
 register definitions and affects the pwm-stm32 driver.

Pull power sequencing updates from Bartosz Golaszewski:
 "This has been in development since last year's Linux Plumbers
  Conference and was inspired by the need to enable support upstream for
  Bluetooth/WLAN chips on Qualcomm platforms.

  The main problem we're fixing is powering up devices which are
  represented as separate objects in the kernel (binding to different
  drivers) but which share parts of the power-up sequence and thus need
  some kind of a mediator who knows the possible interactions and can
  assure they don't interfere with neither device's bring up. An example
  of such an inter-driver interaction is the WCN family of BT/WLAN chips
  from Qualcomm of which some models require the user to observe a
  certain delay between driving the bt-enable and wlan-enable GPIOs.

  This is not a new problem but up to this point all attempts at
  addressing it ended up hitting one wall or another and being dropped.
  The main obstacle was the fact that most these attempts tried to
  introduce the concept of a "power sequence" into the device-tree
  bindings which breaks the main DT rule: describe the hardware, not its
  behavior. The solution I proposed focuses on making the power
  sequencer drivers interpret the actual HW description flexibly. More
  details on that are in the linked cover letter.

  The second problem fixed here is powering up PCI devices before they
  are detected on the bus. This is achieved by creating special platform
  devices for device-tree nodes describing hard-wired PCI devices which
  bind to the so-called PCI power control drivers which enable required
  resources and trigger a bus rescan once the controlled device is up
  then setup the correct devlink hierarchy for power-management.

  By combining the two new frameworks we implemented the power
  sequencing PCI power control driver which is capable of powering up
  the WLAN modules of the QCom WCN family of chipsets.

  All this has spent a significant amount of time in linux-next and
  enabled WLAN/BT support on several Qualcomm platforms. To further
  prove that this is useful and needed: right after this was picked up
  into next, I was sent a series using the subsystem for a similar
  use-case on Amlogic platforms.

  This contains the core power sequencing framework, the first driver,
  PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and
  some fixes that came later"

e091caf99f ARM: SoC fixes for 6.10, part 3
Most of these changes are Qualcomm SoC specific and came in just after
 I sent out the last set of fixes. This includes two regression fixes
 for SoC drivers, a defconfig change to ensure the Lenovo X13s is
 usable and 11 changes to DT files to fix regressions and minor
 platform specific issues.
 
 Tony and Chunyan step back from their respective maintainership roles
 on the omap and unisoc platforms, and Christophe in turn takes over
 maintaining some of the Freescale SoC drivers that he has been taking
 care of in practice already.
 
 Lastly, there are two trivial fixes for the davinci and sunxi
 platforms.

MAINTAINERS: Update FREESCALE SOC DRIVERS and QUICC ENGINE LIBRARY
FREESCALE SOC DRIVERS has been orphaned since
commit eaac25d026 ("MAINTAINERS: Drop Li Yang as their email address
stopped working")
QUICC ENGINE LIBRARY has Qiang Zhao as maintainer but he hasn't
responded for years and when Li Yang was still maintaining FREESCALE
SOC DRIVERS he was also handling QUICC ENGINE LIBRARY directly.

As a maintainer of LINUX FOR POWERPC EMBEDDED PPC8XX AND PPC83XX, I
also need FREESCALE SOC DRIVERS to be actively maintained, so add
myself as maintainer of FREESCALE SOC DRIVERS and QUICC ENGINE LIBRARY.

See below link for more context.

dfd168e74e MAINTAINERS: Add more maintainers for omaps
There are many generations of omaps to maintain, and I will be only active
as a hobbyist with time permitting. Let's add more maintainers to ensure
continued Linux support.

TI is interested in maintaining the active SoCs such as am3, am4 and
dra7. And the hobbyists are interested in maintaining some of the older
devices, mainly based on omap3 and 4 SoCs.

Kevin and Roger have agreed to maintain the active TI parts. Both Kevin
and Roger have been working on the omap variants for a long time, and
have a good understanding of the hardware.

Aaro and Andreas have agreed to maintain the community devices. Both Aaro
and Andreas have long experience on working with the earlier TI SoCs.

While at it, let's also change me to be a reviewer for the omap1, and
drop the link to my old omap web page.

41814fe5c7 pwm: Add driver for AXI PWM generator
Add support for the Analog Devices AXI PWM Generator. This device is an
FPGA-implemented peripheral used as PWM signal generator and can be
interfaced with AXI4. The register map of this peripheral makes it
possible to configure the period and duty cycle of the output signal.

651ab78190 SoC fixes for 6.10, part 2
A number of devicetree fixes came in for the rockchip platforms, correcting
 some of the address information, and reverting a change to the MMC controller
 configuration that caused regressions.
 
 Four drivers have one code change each, addressing minor build issues for
 the optee firmware driver, the litex SoC platform driver and two reset
 drivers.
 
 The riscv fixes as also simple, mainly turning off device nodes in the
 canaan dts files unless they are actually usable on a particular board.
 
 Finally, Drew takes over maintaining the THEAD RISC-V SoC platform.

 "A number of devicetree fixes came in for the rockchip platforms,
  correcting some of the address information, and reverting a change to
  the MMC controller configuration that caused regressions.

  Four drivers have one code change each, addressing minor build issues
  for the optee firmware driver, the litex SoC platform driver and two
  reset drivers.

  The riscv fixes as also simple, mainly turning off device nodes in the
  canaan dts files unless they are actually usable on a particular
  board.

  Finally, Drew takes over maintaining the THEAD RISC-V SoC platform"

c6ed48ef52 power: supply: add ChromeOS EC based charge control driver
The ChromeOS Embedded Controller implements a command to control charge
thresholds and behaviour.

Use it to implement the standard Linux charge_control_start_threshold,
charge_control_end_threshold and charge_behaviour sysfs UAPIs.

The driver is designed to be probed via the cros_ec mfd device.

c7049843db MAINTAINERS: Remembering Larry Finger
We got sad news that Larry is not with us anymore. He was a long time
Linux developer, his first commit was back in 2005 and he has
maintained several wireless drivers over the years. He was known for
patiently supporting Linux users with all sorts of problems they had.
Larry's work helped so many people around the world and I always
enjoyed working with him, even though I sadly never met him.

Rest in Peace, Larry. You will be missed.

Documentation: the design of iomap and how to port
Capture the design of iomap and how to port filesystems to use it.
Apologies for all the rst formatting, but it's necessary to distinguish
code from regular text.

A lot of this has been collected from various email conversations, code
comments, commit messages, my own understanding of iomap, and
Ritesh/Luis' previous efforts to create a document.  Please note a large
part of this has been taken from Dave's reply to last iomap doc
patchset. Thanks to Ritesh, Luis, Dave, Darrick, Matthew, Christoph and
other iomap developers who have taken time to explain the iomap design
in various emails, commits, comments etc.
