4eb15b0363 clk: twl: add clock driver for TWL6032
The TWL6032 has some clock outputs which are controlled like
fixed-voltage regulators, in some drivers for these chips
found in the wild, just the regulator api is abused for controlling
them, so simply use something similar to the regulator functions.
Due to a lack of hardware available for testing, leave out the
TWL6030-specific part of those functions.

2790e2a33a clk: fractional-divider: tests: Add test suite for edge cases
In light of the recent discovery that the fractional divisor
approximation does not utilize the full available range for clocks that
are flagged CLK_FRAC_DIVIDER_ZERO_BASED [1], implement tests for the
edge cases of this clock type.

f8fd5c2483 This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on
    RZ/G2L SMARC EVK

    parent rates when determining clock rates

    for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0

e7dd44f4f3 clk: fixed-mmio: make COMMON_CLK_FIXED_MMIO depend on HAS_IOMEM
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.

Here let COMMON_CLK_FIXED_MMIO depend on HAS_IOMEM so that it won't
be built to cause below compiling error if PCI is unset:

------
ld: drivers/clk/clk-fixed-mmio.o: in function `fixed_mmio_clk_setup':

a9025a5f16 ARM: New SoC support for 6.5
There are two new SoC families this time, and both appear fairly similar:
 The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core
 Cortex-A35 based chips for the low-power industrial embedded market,
 and they mark the first 64-bit product in a widely used family of 32-bit
 Arm MCUs and SoCs.
 
 The way into the kernel is completely different here: The team at ST has
 a long history of working upstream with their STM32MP1 and other SoCs,
 and they produced a complete port to arm64 together with the initial
 announcement. Nuvoton also has multiple SoC product lines with current
 or previous upstream support, but those are maintained by third parties
 and are unrelated. The patch series from Nuvoton's Jacky Huang had to
 go through many revisisions to get to this point and is still missing
 a few drivers including the serial port for the moment.
 
 The branch contains the devicetree files as well as all the code changes,
 in order to have something that can be tested standalone.

Merge tag 'soc-newsoc-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull new ARM SoC support from Arnd Bergmann:
 "There are two new SoC families this time, and both appear fairly
  similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
  both dual-core Cortex-A35 based chips for the low-power industrial
  embedded market, and they mark the first 64-bit product in a widely
  used family of 32-bit Arm MCUs and SoCs.

  The way into the kernel is completely different here: The team at ST
  has a long history of working upstream with their STM32MP1 and other
  SoCs, and they produced a complete port to arm64 together with the
  initial announcement. Nuvoton also has multiple SoC product lines with
  current or previous upstream support, but those are maintained by
  third parties and are unrelated. The patch series from Nuvoton's Jacky
  Huang had to go through many revisisions to get to this point and is
  still missing a few drivers including the serial port for the moment.

  The branch contains the devicetree files as well as all the code
  changes, in order to have something that can be tested standalone"

691521a367 clk: nuvoton: Add clock driver for ma35d1 clock controller
The clock controller generates clocks for the whole chip, including
system clocks and all peripheral clocks. This driver support ma35d1
clock gating, divider, and individual PLL configuration.

There are 6 PLLs in ma35d1 SoC:
  - CA-PLL for the two Cortex-A35 CPU clock
  - SYS-PLL for system bus, which comes from the companion MCU
    and cannot be programmed by clock controller.
  - DDR-PLL for DDR
  - EPLL for GMAC and GFX, Display, and VDEC IPs.
  - VPLL for video output pixel clock
  - APLL for SDHC, I2S audio, and other IPs.
CA-PLL has only one operation mode.
DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3
operation modes: integer mode, fraction mode, and spread specturm mode.

e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.

0ffad67784 clk: HI655X: select REGMAP instead of depending on it
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on REGMAP" to "select REGMAP".

637cee5ffc clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller)
This driver manages Reset and Clock of STM32MP13 soc.
It uses a clk-stm32-core module to manage stm32 gate, mux and divider
for STM32MP13 and for new future soc.

All gates, muxes, dividers are identify by an index and information
are stored in array (register address, shift, with, flags...)
This is useful when we have two clocks with the same gate or
when one mux manages two output clocks.

9512433987 There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each time the
 rate is changed. Previously we wouldn't let clk providers see a rate that was
 different if it was still within the range, which could be bad for power if the
 clk could run slower when a range expands. Now the clk provider can decide to
 do something differently when the constraints change. This broke Nvidia's clk
 driver so we had to wait for the fix for that to bake a little more in -next.
 
 The rate range patch series also introduced a kunit suite for the clk framework
 that we're going to extend in the next release. It already made it easy to find
 corner cases in the rate range patches so I'm excited to see it cover more clk
 code and increase our confidence in core framework patches in the future. I
 also added a kunit test for the basic clk gate code and that work will continue
 to cover more basic clk types: muxes, dividers, etc.
 
 Beyond the core code we have the usual set of clk driver updates and additions.
 Qualcomm again dominates the diffstat here with lots more SoCs being supported
 and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
 Beyond those large additions there's drivers being modernized to use
 clk_parent_data so we can move away from global string names for all the clks
 in an SoC. Finally there's lots of little fixes all over the clk drivers for
 typos, warnings, and missing clks that aren't critical and get batched up
 waiting for the next merge window to open. Nothing super big stands out in the
 driver pile. Full details are below.
 
 Core:
  - Make clk_set_rate_range() re-evaluate the limits each time
  - Introduce various clk_set_rate_range() tests
  - Add clk_drop_range() to drop a previously set range
 
 New Drivers:
  - i.MXRT1050 clock driver and bindings
  - i.MX8DXL clock driver and bindings
  - i.MX93 clock driver and bindings
  - NCO blocks on Apple SoCs
  - Audio clks on StarFive JH7100 RISC-V SoC

  - Qualcomm SDX65 A7 PLL
  - Qualcomm SM6350 GPU clks
  - Qualcomm SM6125, SM6350, QCS2290 display clks
  - Qualcomm MSM8226 multimedia clks
 
 Updates:
  - Kunit tests for clk-gate implementation
  - Terminate arrays with sentinels and make that clearer
  - Cleanup SPDX tags
  - Fix typos in comments
  - Mark mux table as const in clk-mux
  - Make the all_lists array const
  - Convert Cirrus Logic CS2000P driver to regmap, yamlify DT binding and add
    support for dynamic mode
  - Clock configuration on Microchip PolarFire SoCs
  - Free allocations on probe error in Mediatek clk driver
  - Modernize Mediatek clk driver by consolidating code
  - Add watchdog (WDT), I2C, and pin function controller (PFC) clocks on
    Renesas R-Car S4-8
  - Improve the clocks for the Rockchip rk3568 display outputs (parenting, pll-rates)
  - Use of_device_get_match_data() instead of open-coding on Rockchip rk3568
  - Reintroduce the expected fractional-divider behaviour that disappeared
    with the addition of CLK_FRAC_DIVIDER_POWER_OF_TWO_PS
  - Remove SYS PLL 1/2 clock gates for i.MX8M*
  - Remove AUDIO MCLK ROOT from i.MX7D

455e73a07f We have a couple patches in the framework core this time around but
they're mostly minor cleanups and some debugfs stuff. The real work
 that's in here is the typical pile of clk driver updates and new SoC
 support. Per usual (or maybe just recent trends), Qualcomm gains a
 handful of SoC drivers additions and has the largest diffstat. After
 that there are quite a few updates to the Allwinner (sunxi) drivers to
 support modular drivers and Renesas is heavily updated to add more
 support for various clks. Overall it looks pretty normal.
 
 New Drivers:
  - Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770
  - MediaTek mt7986 SoC basic support
  - Clock and reset driver for Toshiba Visconti SoCs

  - Switch from do_div to div64_ul for throughout all i.MX drivers
  - Fix imx8mn_clko1_sels for i.MX8MN

5dcc0ef887 clk: Drop unused COMMON_CLK_STM32MP157_SCMI config
Commit 21e743300d ("clk: stm32mp1: new compatible for secure RCC support")
introduced a new Kconfig option COMMON_CLK_STM32MP157_SCMI which is not
used anywhere.

Further, it looks like this Kconfig option is just to select bunch of other
options which doesn't sound correct to me. There is no need for another
SCMI firmware based clock driver and hence the same applies for the config
option too.

Let us just drop the unused COMMON_CLK_STM32MP157_SCMI before it gives
someone idea to write a specific clock driver for this SoC/platform.

ff5f87cb6a clk: Introduce clk-tps68470 driver
The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in
the kernel the Regulators and Clocks are controlled by an OpRegion
driver designed to work with power control methods defined in ACPI, but
some platforms lack those methods, meaning drivers need to be able to
consume the resources of these chips through the usual frameworks.

This commit adds a driver for the clocks provided by the tps68470,
and is designed to bind to the platform_device registered by the
intel_skl_int3472 module.

This is based on this out of tree driver written by Intel:
https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/clk/clk-tps68470.c
with various cleanups added.

21e743300d clk: stm32mp1: new compatible for secure RCC support
Platform STM32MP1 can be used in configuration where some clock
resources cannot be accessed by Linux kernel when executing in non-secure
state of the CPU(s).
In such configuration, the RCC clock driver must not register clocks
it cannot access.
They are expected to be registered from another clock driver such
as the SCMI clock driver.
This change uses specific compatible string "st,stm32mp1-rcc-secure"
to specify RCC clock driver configuration where RCC is secure.

fa5b654142 clk: bd718xx: Drop BD70528 support
The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.
