The DesignWare I2C can not be operated as I2C master and
I2C slave simultaneously, but that does not actually mean
master and slave modes can not be supported at the same
time. It just means an explicit mode swap needs to be
executed when the mode is changed. The DesignWare I2C
documentation actually describes a couple of cases where the
mode is excepted to be changed.
The I2C master will now always be supported. Both modes are
now always configured in i2c_dw_configure(), but the slave
mode will continue to be available only when the Kconfig
option I2C_SLAVE is enabled.
The driver will now start in master mode and then swap to
slave mode when a slave device is registered. After a slave
device is registered, the controller is swapped to master
mode when a transfer in master mode is started and then back
to slave mode again after the transfer is completed.
The DesignWare I2C can now be used with protocols such as
MCTP (drivers/net/mctp/mctp-i2c.c) and IPMI
(drivers/char/ipmi/) that require support for both I2C
master and I2C slave. It is now also possible to support the
SMBus Host Notification Protocol as I2C master if needed.

to the interrupt.
The dedicated "target only" (slave only) configuration

On i.MX8QXP/8QM SoCs, both the lvds/mipi and lvds/mipi-lpi2c power domains
must enter low-power mode during runtime suspend to achieve deep power
savings.
LPI2C resides in the lvds-lpi2c/mipi-lpi2c power domain, while its IRQ is
routed through an irqsteer located in the lvds/mipi power domain. The LPI2C
clock source comes from an LPCG within the lvds-lpi2c domain.
For example, the hierarchy for lvds0 and lvds0-lpi2c0 domains is:
┌───────────────────────┐
│ pm-domain : lvds0 │
│ │
│ ┌──────────────┐ │
│ │ irqsteer │ │
│ └───────▲──────┘ │
│ │irq │
│ │ │
└────────────┼──────────┘
┌────────────┼──────────┐
│ ┌───┼───┐ │
│ │lpi2c0 │ │
│ └───┬───┘clk │
│ ┌────────┼───────┐ │
│ │ LPCG │ │
│ └────────────────┘ │
│pm-domain:lvds0-lpi2c0 │
└───────────────────────┘
To allow these domains to power down in system runtime suspend:
- All irqsteer clients must release IRQs.
- All LPCG clients must disable and unprepare clocks.
Thus, LPI2C must:
- Free its IRQ during runtime suspend and re-request it on resume.
- Disable and unprepare all clocks during runtime suspend and prepare
and rne ble them on resume.
This enables the lvds/mipi domains to enter deep low-power mode,
significantly reducing power consumption compared to active mode.

Theoretically it's possible that fwnode is returned by some API,
that may return an error pointer (and we have, for example,
fwnode_find_reference() which does that). If such an fwnode
is supplied to the i2c core APIs the functions will perform
unneeded loops and checks. Avoid this by preventively checking

Add support for SW mutex register introduced in Tegra264 to provide
an option to share the interface between multiple firmwares and/or
VMs. This involves following steps:
- A firmware/OS writes its unique ID to the mutex REQUEST field.
- Ownership is established when reading the GRANT field returns the
same ID.
- If GRANT shows a different non-zero ID, the firmware/OS retries
until timeout.
- After completing access, it releases the mutex by writing 0.
However, the hardware does not ensure any protection based on the
values. The driver/firmware should honor the peer who already holds
the mutex.

Included in here are:
- serial sysfs fwnode fix that was much reported
- sh-sci driver fix
- serial device init bugfix
- 8250 bugfix
- xilinx_uartps bugfix
All of these have passed 0-day testing and individual testing

A fix for PCI driver for Texas Instruments PCILyx series. The driver had
a bug where it allocated a DMA-coherent buffer of 16 KB but released it
using PAGE_SIZE. This disproportion was reported in 2020, but the fix was
never merged. It is finally resolved.

- Add probing and userspace reporting support for the standard RISC-V
ISA extensions Zilsd and Zclsd, which implement load/store dual
instructions on RV32
- Abstract the register saving code in setup_sigcontext() so it can be
used for stateful RISC-V ISA extensions beyond the vector extension
- Add the SBI extension ID and some initial data structure definitions
for the RISC-V standard SBI debug trigger extension
- Clean up some code slightly: change some page table functions to
avoid atomic operations oinn !SMP and to avoid unnecessary casts to
atomic_long_t; and use the existing RISCV_FULL_BARRIER macro in
place of some open-coded "fence rw,rw" instructions

The generic option for I2C target is already user selectable,
which makes the DesignWare specific option completely
unnecessary. The DesignWare option also silently selected
I2C_SLAVE instead of depending on it without any real need
for it.

We've got more fixes here for the Cadence QSPI controller, this time
fixing some issues that come up when working with slower flashes on some
platforms plus a general race condition.
We also add support for the Allwinner A523, this is just some new
