Merge tag 'soc-drivers-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
"There are are a number of to firmware drivers, in particular the TEE
subsystem:

- a bus callback for TEE firmware that device drivers can register to

- sysfs support for tee firmware information

- minor updates to platform specific TEE drivers for AMD, NXP,
Qualcomm and the generic optee driver

- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups

- ARM FF-A firmware interoperability improvements

The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.

Most of the other changes are for random drivers/soc code. Among a
number of cleanups and newly added hardware support, including:

- Mediatek MT8196 DVFS power management and mailbox support

- Qualcomm SCM firmware and MDT loader refactoring, as part of the
new Glymur platform support.

- NXP i.MX9 System Manager firmware support for accessing the syslog

- Minor updates for TI, Renesas, Samsung, Apple, Marvell and AMD
SoCs"

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.

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

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
- Samsung ACPM (firmware interface) clock driver

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.

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.

Merge tag 'gpio-updates-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.

The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.

GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code

New drivers:
- add a driver for the QIXIS FPGA GPIO controller

Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio

Device-tree bindings:
- document new NXP and Microchip models

Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks

Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"
