 "The bulk of the changes in this release are driver work, as well as
  new device support we have some important work on performance over
  several drivers, and big overhauls for maintainability on a couple
  too. Highlights include:

   - Big cleanups of the sh-msiof driver from Geert Uytterhoeven, and of
     the NXP FSPI driver from Haibo Chen

   - Performance improvements for the AXI SPI engine

   - Support for writes to memory mapped flashes on Renesas devices

   - Integrated DMA support for Tegra210 QSPI, used by the Tegra234

   - DMA support for Amlogic SPI controllers

   - Support for AMD HID2, Qualcomm IPQ5018, Renesas RZ/G3E, Rockchip
     RK3528 and Samsung Exynos Autov920

  An update to fix some issues with the Atmel QSPI driver runtime PM
  pulled in a new API from the PM core, and the Renesas memory mapped
  write changes pull in some code that's shared in drivers/memory"

8529e33bfe memory: omap-gpmc: Switch to irq_domain_create_linear()
irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.

Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

8181d061dc memory: Add STM32 Octo Memory Manager driver
Octo Memory Manager driver (OMM) manages:
  - the muxing between 2 OSPI busses and 2 output ports.
    There are 4 possible muxing configurations:
      - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
        output is on port 2
      - OSPI1 and OSPI2 are multiplexed over the same output port 1
      - swapped mode (no multiplexing), OSPI1 output is on port 2,
        OSPI2 output is on port 1
      - OSPI1 and OSPI2 are multiplexed over the same output port 2
  - the split of the memory area shared between the 2 OSPI instances.
  - chip select selection override.
  - the time between 2 transactions in multiplexed mode.
  - check firewall access.

b9784e5cde memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()
As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.

This bug was found by an experimental verification tool that I am
developing.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.
