2875b4b5d2 reset: Create subdirectory for SpacemiT drivers
Create a dedicated subdirectory for SpacemiT reset drivers to allow
for better organization as support for more SoCs is added.

Move the existing K1 reset driver into this new directory and rename
it to reset-spacemit-k1.c.

Rename the Kconfig symbol to RESET_SPACEMIT_K1 and update its default
from ARCH_SPACEMIT to SPACEMIT_K1_CCU. The reset driver depends on the
clock driver to register reset devices as an auxiliary device, so the
default should reflect this dependency.

Also sort the drivers/reset/Kconfig entries alphabetically.

Pull clk updates from Stephen Boyd:
 "This is entirely SoC clk drivers.

  The majority diff wise is for the new Rockchip and Qualcomm clk
  drivers which is mostly lines and lines of data structures to describe
  the clk hardware in these SoCs. Beyond those two, Renesas continues to
  incrementally add clks to their SoC drivers, causing them to show up
  higher in the diffstat this time because they added quite a few clks
  all over the place.

  Overall it is a semi-quiet release that has some new clk drivers and
  the usual fixes for clock data that was wrong or missing and
  non-critical cleanups that plug error paths or fix typos.

  New Drivers:
   - Qualcomm IPQ5424 Network Subsystem Clock Controller
   - Qualcomm SM8750 Video Clock Controller
   - Rockchip RV1126B and RK3506 clock drivers
   - i.MX8ULP SIM LPAV clock driver

78f2d64e48 reset: rzg2l-usbphy-ctrl: Add support for USB PWRRDY
On the Renesas RZ/G3S SoC, the USB PHY block has an input signal called
PWRRDY. This signal is managed by the system controller and must be
de-asserted after powering on the area where USB PHY resides and asserted
before powering it off.

On power-on/resume the USB PWRRDY signal need to be de-asserted before
enabling clock and switching the module to normal state (through MSTOP
support). The power-on/resume configuration sequence must be:

1/ PWRRDY=0
2/ CLK_ON=1
3/ MSTOP=0

On power-off/suspend the configuration sequence should be:

1/ MSTOP=1
2/ CLK_ON=0
3/ PWRRDY=1

The CLK_ON and MSTOP functionalities are controlled by clock drivers.
The suspend/resume support will be handled by different patches.

After long discussions with the internal HW team, it has been confirmed
that the HW connection b/w USB PHY block, the USB channels, the system
controller, clock, MSTOP, PWRRDY signal is as follows:

where:
- CPG_CLKON_USB.CLK.CLKX_ON is the register bit controlling the clock X
  of different USB blocks, X in {0, 1, 2, 3}
- CPG_BUS_PERI_COM_MSTOP.MSTOPX_ON is the register bit controlling the
  MSTOP of different USB blocks, X in {4, 5, 6, 7}
- USB PHY is the USB PHY block exposing 2 ports, port0 and port1, used
  by the USB CH0, USB CH1
- SYSC is the system controller block controlling the PWRRDY signal
- USB CHx are individual USB block with host and function capabilities
  (USB CH0 have both host and function capabilities, USB CH1 has only
  host capabilities)

The USBPHY control registers are controlled though the
reset-rzg2l-usbphy-ctrl driver. The USB PHY ports are controlled by
phy_rcar_gen3_usb2 (drivers/phy/renesas/phy-rcar-gen3-usb2.c file). The
USB PHY ports request resets from the reset-rzg2l-usbphy-ctrl driver.

The connection b/w the system controller and the USB PHY CTRL driver is
implemented through the renesas,sysc-pwrrdy device tree property
proposed in this patch. This property specifies the register offset and the
bitmask required to control the PWRRDY signal.

Since the USB PHY CTRL driver needs to be probed before any other
USB-specific driver on RZ/G3S, control of PWRRDY is passed exclusively
to it. This guarantees the correct configuration sequence between clocks,
MSTOP bits, and the PWRRDY bit on probe/resume and remove/suspend. At the
same time, changes are kept minimal by avoiding modifications to the USB
PHY driver to also handle the PWRRDY itself.

781f60e45b reset: mpfs: add non-auxiliary bus probing
While the auxiliary bus was a nice bandaid, and meant that re-writing
the representation of the clock regions in devicetree was not required,
it has run its course. The "mss_top_sysreg" region that contains the
clock and reset regions, also contains pinctrl and an interrupt
controller, so the time has come rewrite the devicetree and probe the
reset controller from an mfd devicetree node, rather than implement
those drivers using the auxiliary bus. Wanting to avoid propagating this
naive/incorrect description of the hardware to the new pic64gx SoC is a
major motivating factor here.

Pull clk updates from Stephen Boyd:
 "This is the usual collection of primarily clk driver updates.

  The big part of the diff is all the new Qualcomm clk drivers added for
  a few SoCs they're working on. The other two vendors with significant
  work this cycle are Renesas and Amlogic. Renesas adds a bunch of clks
  to existing drivers and supports some new SoCs while Amlogic is
  starting a significant refactoring to simplify their code.

  The core framework gained a pair of helpers to get the 'struct device'
  or 'struct device_node' associated with a 'struct clk_hw'. Some
  associated KUnit tests were added for these simple helpers as well.

  Beyond that core change there are lots of little fixes throughout the
  clk drivers for the stuff we see every day, wrong clk driver data that
  affects tree topology or supported frequencies, etc. They're not found
  until the clks are actually used by some consumer device driver.

  New Drivers:
   - Global, display, gpu, video, camera, tcsr, and rpmh clock
     controller for the Qualcomm Milos SoC
   - Camera, display, GPU, and video clock controllers for Qualcomm
     QCS615
   - Video clock controller driver for Qualcomm SM6350
   - Camera clock controller driver for Qualcomm SC8180X
   - I3C clocks and resets on Renesas RZ/G3E
   - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
     Renesas RZ/V2H(P) and RZ/V2N
   - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
   - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
   - Ethernet clocks and resets on Renesas RZ/G3E
   - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
     (R9A09G087) SoCs
   - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
   - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
     RZ/V2N

  Updates:
   - Support atomic PWMs in the PWM clk driver
   - clk_hw_get_dev() and clk_hw_get_of_node() helpers
   - Replace round_rate() with determine_rate() in various clk drivers
   - Convert clk DT bindings to DT schema format for DT validation
   - Various clk driver cleanups and refactorings from static analysis
     tools and possibly real humans
   - A lot of little fixes here and there to things like clk tree
     topology, missing frequencies, flagging clks as critical, etc"

Pull SoC driver updates from Arnd Bergmann:
 "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"

13678f3feb reset: ti-sci: honor TI_SCI_PROTOCOL setting when not COMPILE_TEST
There is a build error when COMPILE_TEST=y, TI_SCI_PROTOCOL=m,
and RESET_TI_SCI=y:

drivers/reset/reset-ti-sci.o: in function `ti_sci_reset_probe':
reset-ti-sci.c:(.text+0x22c): undefined reference to `devm_ti_sci_get_handle'

Fix this by making RESET_TI_SCI honor the Kconfig setting of
TI_SCI_PROTOCOL when COMPILE_TEST is not set. When COMPILE_TEST is set,
TI_SCI_PROTOCOL must be disabled (=n).

bdc753c7fc Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
 "We have some late breaking reports that a patch series to rework clk
  rate range support broke boot on some devices, so I've left that
  branch out of this. Hopefully we can get to that next week, or punt on
  it and let it bake another cycle. That means we don't really have any
  changes to the core framework this time around besides a few typo
  fixes. Instead this is all clk driver updates and fixes.

  The usual suspects are here (again), with Qualcomm dominating the
  diffstat. We look to have gained support for quite a few new Qualcomm
  SoCs and Dmitry worked on updating many of the existing Qualcomm
  drivers to use clk_parent_data. After that we have MediaTek drivers
  getting some much needed updates, in particular to support GPU DVFS.
  There are also quite a few Samsung clk driver patches, but that's
  mostly because there was a maintainer change and so last release we
  missed some of those patches.

  Overall things look normal, but I'm slowly reviewing core framework
  code nowadays and that shows given the rate range patches had to be
  yanked last minute. Let's hope this situation changes soon.

  New Drivers:
   - Support for Renesas VersaClock7 clock generator family
   - Add Spreadtrum UMS512 SoC clk support
   - New clock drivers for MediaTek Helio X10 MT6795
   - Display clks for Qualcomm SM6115, SM8450
   - GPU clks for Qualcomm SC8280XP
   - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers

  Deleted Drivers:
   - Remove DaVinci DM644x and DM646x clk driver support

  Updates:
   - Convert Baikal-T1 CCU driver to platform driver
   - Split reset support out of primary Baikal-T1 CCU driver
   - Add some missing clks required for RPiVid Video Decoder on
     RaspberryPi
   - Mark PLLC critical on bcm2835
   - More devm helpers for fixed rate registration
   - Various PXA168 clk driver fixes
   - Add resets for MediaTek MT8195 PCIe and USB
   - Miscellaneous of_node_put() fixes
   - Nuke dt-bindings/clk path (again) by moving headers to
     dt-bindings/clock
   - Convert gpio-clk-gate binding to YAML
   - Various fixes to AMD/Xilinx Zynqmp clk driver
   - Graduate AMD/Xilinx "clocking wizard" driver from staging
   - Add missing DPI1_HDMI clock in MT8195 VDOSYS1
   - Clock driver changes to support GPU DVFS on MT8183, MT8192, MT8195
   - Fix GPU clock topology on MT8195
   - Propogate rate changes from GPU clock gate up the tree
   - Clock mux notifiers for GPU-related PLLs
   - Conversion of more "simple" drivers to mtk_clk_simple_probe()
   - Hook up mtk_clk_simple_remove() for "simple" MT8192 clock drivers
   - Fixes to previous |struct clk| to |struct clk_hw| conversion on
     MediaTek
   - Shrink MT8192 clock driver by deduplicating clock parent lists
   - Change order between 'sim_enet_root_clk' and 'enet_qos_root_clk'
     clocks for i.MX8MP
   - Drop unnecessary newline in i.MX8MM dt-bindings
   - Add more MU1 and SAI clocks dt-bindings Ids
   - Introduce slice busy bit check for i.MX93 composite clock
   - Introduce white list bit check for i.MX93 composite clock
   - Add new i.MX93 clock gate
   - Add MU1 and MU2 clocks to i.MX93 clock provider
   - Add SAI IPG clocks to i.MX93 clock provider
   - add generic clocks for U(S)ART available on SAMA5D2 SoCs
   - reset controller support for Polarfire clocks
   - .round_rate and .set rate support for clk-mpfs
   - code cleanup for clk-mpfs
   - PLL support for PolarFire SoC's Clock Conditioning Circuitry
   - Add watchdog, I2C, pin control/GPIO, and Ethernet clocks on R-Car
     V4H
   - Add SDHI, Timer (CMT/TMU), and SPI (MSIOF) clocks on R-Car S4-8
   - Add I2C clocks and resets on RZ/V2M
   - Document clock support for the RZ/Five SoC
   - mux-variant clock using the table variant to select parents
   - clock controller for the rv1126 soc
   - conversion of rk3128 to yaml and relicensing of the yaml bindings
     to gpl2+MIT (following dt-binding guildelines)
   - Exynos7885: add FSYS, TREX and MFC clock controllers
   - Exynos850: add IS and AUD (audio) clock controllers with bindings
   - ExynosAutov9: add FSYS clock controllers with bindings
   - ExynosAutov9: correct clock IDs in bindings of Peric 0 and 1 clock
     controllers, due to duplicated entries. This is an acceptable ABI
     break: recently developed/added platform so without legacies, acked
     by known users/developers
   - ExynosAutov9: add few missing Peric 0/1 gates
   - ExynosAutov9: correct register offsets of few Peric 0/1 clocks
   - Minor code improvements (use of_device_get_match_data() helper,
     code style)
   - Add Krzysztof Kozlowski as co-maintainer of Samsung SoC clocks, as
     he already maintainers that architecture/platform
   - Keep Qualcomm GDSCs enabled when PWRSTS_RET flag is there, solving
     retention issues during suspend of USB on Qualcomm sc7180/sc7280
     and SC8280XP
   - Qualcomm SM6115 and QCM2260 are moved to reuse PLL configuration
   - Qualcomm SDM660 SDCC1 moved to floor clk ops
   - Support for the APCS PLLs for Qualcomm IPQ8064, IPQ8074 and IPQ6018
     was added/fixed
   - The Qualcomm MSM8996 CPU clocks are updated with support for ACD
   - Support for Qualcomm SDM670 GCC and RPMh clks was added
   - Transition to parent_data, parent_hws and use of ARRAY_SIZE() for
     num_parents was done for many Qualcomm SoCs
   - Support for per-reset defined delay on Qualcomm was introduced"

05f9e36370 reset: add polarfire soc reset support
Add support for the resets on Microchip's PolarFire SoC (MPFS).
Reset control is a single register, wedged in between registers for
clock control. To fit with existed DT etc, the reset controller is
created using the aux device framework & set up in the clock driver.

8a4e6154fb reset: tps380x: Add TPS380x device driver supprt
The TI TPS380x family [1] is a voltage supervisor with a dedicated
manual reset (mr) line input and a reset output. The chip(s) have a
build in reset delay, depending on the chip partnumber. This simple
driver addresses this so the cosumer don't need to care about it.
