cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

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.

9f3a2ba62c The core framework gained a clk provider helper, a clk consumer helper, and
some unit tests for the assigned clk rates feature in DeviceTree. On the vendor
 driver side, we gained a whole pile of SoC driver support detailed below. The
 majority in the diffstat is Qualcomm, but there's also quite a few Samsung and
 Mediatek clk driver additions in here as well. The top vendors is quite common,
 but the sheer amount of new drivers is uncommon, so I'm anticipating a larger
 number of fixes for clk drivers this cycle.
 
 Core:
  - devm_clk_bulk_get_all_enabled() to return number of clks acquired
  - devm_clk_hw_register_gate_parent_hw() helper to modernize drivers
  - KUnit tests for clk-assigned-rates{,-u64}
 
 New Drivers:
  - Marvell PXA1908 SoC clks
  - Mobileye EyeQ5, EyeQ6L and EyeQ6H clk driver
  - TWL6030 clk driver
  - Nuvoton Arbel BMC NPCM8XX SoC clks
  - MediaTek MT6735 SoC clks
  - MediaTek MT7620, MT7628 and MT7688 MMC clks
  - Add a driver for gated fixed rate clocks
  - Global clock controllers for Qualcomm QCS8300 and IPQ5424 SoCs
  - Camera, display and video clock controllers for Qualcomm SA8775P SoCs
  - Global, display, GPU, TCSR, and RPMh clock controllers for Qualcomm SAR2130P
  - Global, camera, display, GPU, and video clock controllers for Qualcomm
    SM8475 SoCs
  - RTC power domain and Battery Backup Function (VBATTB) clock support for the
    Renesas RZ/G3S SoC
  - Qualcomm IPQ9574 alpha PLLs
  - Support for i.MX91 CCM in the i.MX93 driver
  - Microchip LAN969X SoC clks
  - Cortex-A55 core clocks and Interrupt Control Unit (ICU) clock and reset on
    Renesas RZ/V2H(P)
  - Samsung ExynosAutov920 clk drivers for PERIC1, MISC, HSI0 and HSI1
  - Samsung Exynos8895 clk drivers for FSYS0/1, PERIC0/1, PERIS and TOP
 
 Updates:
  - Convert more clk bindings to YAML
  - Various clk driver cleanups: NULL checks, add const, etc.
  - Remove END/NUM #defines that count number of clks in various binding headers
  - Continue moving reset drivers to drivers/reset via auxiliary bus

0426a920d6 reset: mchp: sparx5: Map cpu-syscon locally in case of LAN966x
In the LAN966x PCI device use case, the syscon API cannot be used as
it does not support device removal [1]. A syscon device is a core
"system" device and not a device available in some addon boards and so,
it is not supposed to be removed. The syscon API follows this assumption
but this assumption is no longer valid in the LAN966x use case.

In order to avoid the use of the syscon API and so, support for removal,
use a local mapping of the syscon device.

dad35f7d2f reset: replace boolean parameters with flags parameter
Introduce enum reset_control_flags and replace the list of boolean
parameters to the internal reset_control_get functions with a single
flags parameter, before adding more boolean options.

The separate boolean parameters have been shown to be error prone in
the past. See for example commit a57f68ddc8 ("reset: Fix devm bulk

c2a96b7f18 Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

cc0f7c3f97 soc: driver updates for 6.11
The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
 samsung, imx, zynq and amlogic platoforms are farily small maintenance
 changes, either addressing minor mistakes or enabling additional hardware.
 
 The qualcomm platform changes add a number of features and are larger
 than the other ones combined, introducing the use of linux/cleanup.h
 across several drivers, adding support for Snapdragon X1E and other
 SoCs in platform drivers, a new "protection domain mapper" driver, and a
 "shared memory bridge" driver.
 
 The cznic "turris omnia" router based on Marvell Armada gets a platform
 driver that talks to the board specific microcontroller.
 
 The reset and cache subsystems get a few minor updates to SoC specific
 drivers, while the ff-a, scmi and optee firmware drivers get some
 code refactoring and new features.

 "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
  samsung, imx, zynq and amlogic platoforms are fairly small maintenance
  changes, either addressing minor mistakes or enabling additional
  hardware.

  The qualcomm platform changes add a number of features and are larger
  than the other ones combined, introducing the use of linux/cleanup.h
  across several drivers, adding support for Snapdragon X1E and other
  SoCs in platform drivers, a new "protection domain mapper" driver, and
  a "shared memory bridge" driver.

  The cznic "turris omnia" router based on Marvell Armada gets a
  platform driver that talks to the board specific microcontroller.

  The reset and cache subsystems get a few minor updates to SoC specific
  drivers, while the ff-a, scmi and optee firmware drivers get some code
  refactoring and new features"

619b92b9c8 I'm actually surprised this time. There aren't any new Qualcomm SoC clk
drivers. And there's zero diff in the core clk framework. Instead we have new
 clk drivers for STM and Sophgo, with Samsung^WGoogle in third for the diffstat
 because they introduced HSI0 and HSI2 clk drivers for Google's GS101 SoC (high
 speed interface things like PCIe, UFS, and MMC). Beyond those big diffs there's
 the usual updates to various clk drivers for incorrect parent descriptions or
 mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
 interesting here.
 
 New Drivers:
  - STM32MP257 SoC clk driver
  - Airoha EN7581 SoC clk driver
  - Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
  - Loongson-2k0500 and Loongson-2k2000 SoC clk driver

  - Fix the Qualcomm APSS IPQ5018 PLL to fix boot failures of some boards
  - Cleanups and fixes for Qualcomm Stromer PLLs

  - Fix Kconfig dependencies of Qualcomm SM8650 GPU and SC8280XP camera
    clk drivers
  - Make Qualcomm MSM8998 Venus clocks functional

  - Use a specific Qualcomm QCS404 compatible for the otherwise generic
    HFPLL
  - Remove Qualcomm SM8150 CPUSS AHB clk as it is unused
  - Remove an unused field in the Qualcomm RPM clk driver
  - Add missing MODULE_DEVICE_TABLE to Qualcomm MSM8917 and MSM8953
    global clock controller drivers
  - Allow choice of manual or firmware-driven control over PLLs, needed
    to fully implement CPU clock controllers on Exynos850
  - Correct PLL clock IDs on ExynosAutov9
  - Propagate certain clock rates to allow setting proper SPI clock

6d89df6165 reset: ti-sci: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
