networking and permanent storage that are currently even more common

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.

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".

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.

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

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"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

Add driver for Renesas 9-series PCIe clock generators. This driver
is designed to support 9FGV/9DBV/9DMV/9FGL/9DML/9QXL/9SQ series I2C
PCIe clock generators, currently the only tested and supported chip
is 9FGV0241.
The driver is capable of configuring per-chip spread spectrum mode
and output amplitude, as well as per-output slew rate.

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.

- Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770
- MediaTek mt7986 SoC basic support
- Clock and reset driver for Toshiba Visconti SoCs
- Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8)

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.

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.

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.

The documentation for this SOC only talks about two
registers regarding to the clocks:
* SYSC_REG_CPLL_CLKCFG0 - provides some information about
boostrapped refclock. PLL and dividers used for CPU and some
sort of BUS.
* SYSC_REG_CPLL_CLKCFG1 - a banch of gates to enable/disable
clocks for all or some ip cores.
Looking into driver code, and some openWRT patched there are
another frequencies which are used in some drivers (uart, sd...).
According to all of this information the clock plan for this
SoC is set as follows:
- Main top clock "xtal" from where all the rest of the world is
derived.
- CPU clock "cpu" derived from "xtal" frequencies and a bunch of
register reads and predividers.
- BUS clock "bus" derived from "cpu" and with (cpu / 4) MHz.
- Fixed clocks from "xtal":
* "50m": 50 MHz.
* "125m": 125 MHz.
* "150m": 150 MHz.
* "250m": 250 MHz.
* "270m": 270 MHz.
We also have a buch of gate clocks with their parents:
* "hsdma": "150m"
* "fe": "250m"
* "sp_divtx": "270m"
* "timer": "50m"
* "pcm": "270m"
* "pio": "50m"
* "gdma": "bus"
* "nand": "125m"
* "i2c": "50m"
* "i2s": "270m"
* "spi": "bus"
* "uart1": "50m"
* "uart2": "50m"
* "uart3": "50m"
* "eth": "50m"
* "pcie0": "125m"
* "pcie1": "125m"
* "pcie2": "125m"
* "crypto": "250m"
* "shxc": "50m"
With this information the clk driver will provide clock and gates
functionality from a a set of hardcoded clocks allowing to define
a nice device tree without fixed clocks.

The Intel's eASIC N5X (ARCH_N5X) architecture shares a lot with Agilex
(ARCH_AGILEX) so it uses the same socfpga_agilex.dtsi, with minor
changes. Also the clock drivers are the same.
However the clock drivers won't be build without ARCH_AGILEX. One could
assume that ARCH_N5X simply depends on ARCH_AGILEX but this was not
modeled in Kconfig. In current stage the ARCH_N5X is simply
unbootable.
Add a separate Kconfig entry for clocks used by both ARCH_N5X and
ARCH_AGILEX so the necessary objects will be built if either of them is
selected.

Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC.
This new driver with the compatible string "canaan,k210-clk" implements
support for the full clock structure of the K210 SoC. Since it is
required for the correct operation of the SoC, this driver is
selected by default for compilation when the SOC_CANAAN option is
selected.
With this change, the k210-sysctl driver is turned into a simple
platform driver which enables its power bus clock and triggers
populating its child nodes. The sysctl driver retains the SOC early
initialization code, but the implementation now relies on the new
function k210_clk_early_init() provided by the new clk-k210 driver.
The clock structure implemented and many of the coding ideas for the
driver come from the work by Sean Anderson on the K210 support for the
U-Boot project.
