b492183652 i2c: mediatek: fix potential incorrect use of I2C_MASTER_WRRD
The old IC does not support the I2C_MASTER_WRRD (write-then-read)
function, but the current code’s handling of i2c->auto_restart may
potentially lead to entering the I2C_MASTER_WRRD software flow,
resulting in unexpected bugs.

Instead of repurposing the auto_restart flag, add a separate flag
to signal I2C_MASTER_WRRD operations.

Also fix handling of msgs. If the operation (i2c->op) is
I2C_MASTER_WRRD, then the msgs pointer is incremented by 2.
For all other operations, msgs is simply incremented by 1.

1a2b423be6 i2c: boardinfo: Annotate code used in init phase only
Annotate two places in boardinfo code:
- __i2c_first_dynamic_bus_num is set in init phase. Annotate it as
  __ro_after_init to prevent later changes.
- i2c_register_board_info() is used in init phase only, so annotate it
  as __init, allowing to free the memory after init phase.
  This is safe, see comment: "done in board-specific init code near
  arch_initcall() time"

eddfe53b0d i2c: core: Drop dev_pm_domain_detach() call
Starting with commit f99508074e ("PM: domains: Detach on
device_unbind_cleanup()"), there is no longer a need to call
dev_pm_domain_detach() in the bus remove function. The
device_unbind_cleanup() function now handles this to avoid
invoking devres cleanup handlers while the PM domain is
powered off, which could otherwise lead to failures as
described in the above-mentioned commit.

Drop the explicit dev_pm_domain_detach() call and rely instead
on the flags passed to dev_pm_domain_attach() to power off the
domain.

Remove existing arbitration timeout macros and use I2C adapter timeout
value for arbitration timeout and forceful bus ownership.

I2C adapter timeout can be configurable from user space, so using it
for arbitration timeout helps in configuring the arbitration timeout

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,i2c" anymore [1]. Use
"apple,t8103-i2c" as fallback compatible as it is the SoC the driver

This block is compatible with t8103, so just add the new per-SoC
compatible using apple,t8103-i2c as base.

d32bb69523 i2c: core: Use fwnode_for_each_child_node_scoped()
Replace the manual __free(fwnode_handle) iterator declaration with the
new scoped iterator macro for cleaner, less error-prone code.

This eliminates the need for explicit iterator variable declaration with
the cleanup attribute, making the code more consistent with other scoped
iterator usage patterns in the kernel.

448097bbd3 device property: Add scoped fwnode child node iterators
Add scoped versions of fwnode child node iterators that automatically
handle reference counting cleanup using the __free() attribute:

- fwnode_for_each_child_node_scoped()
- fwnode_for_each_available_child_node_scoped()

These macros follow the same pattern as existing scoped iterators in the
kernel, ensuring fwnode references are automatically released when the
iterator variable goes out of scope. This prevents resource leaks and
eliminates the need for manual cleanup in error paths.

The implementation mirrors the non-scoped variants but uses
__free(fwnode_handle) for automatic resource management, providing a
safer and more convenient interface for drivers iterating over firmware
node children.

94c2967764 i2c: muxes: pca954x: Reset if (de)select fails
If the channel selection or deselection times out, it indicates
a failure in the mux's I2C subsystem. Without sending a reset pulse,
a power-on-reset of the entire device would be required to restore
communication.

The datasheet specifies a minimum hold time of 4 ns for the reset
pulse, but due to the path's capacitance and themux having its own
clock, it is recommended to extend this to approximately 1 us.

Since reset controller is used, there is no need to take care of other
devices sharing the same reset line.

   FWIW, kudos to the syzbot crew for having much nicer reproducers now,
   and with nicely annotated source code as well. This is particularly
