2025-07-25i2c: lpi2c: implement xfer_atomic callbackEmanuele Ghidoli
Rework the read and write code paths in the driver to support operation in atomic contexts. To achieve this, the driver must not rely on IRQs or perform any scheduling, e.g., via a sleep or schedule routine. Implement atomic, sleep-free, and IRQ-less operation. This increases complexity but is necessary for atomic I2C transfers required by some hardware configurations, e.g., to trigger reboots on an external PMIC chip.

2025-07-25dt-bindings: i2c: i2c-rk3x: Allow use of a power-domainJonas Karlman
The I2C controllers in most Rockchip SoCs are part of power domains that are always powered on, i.e. PD_BUS or PD_PMU. These always powered on power domains have typically not been described in the device tree. Because these power domains have been left out of the device tree there has not been any real need to properly describe the I2C controllers power domain. On RK3528 the I2C controllers are spread out among the described PD_RKVENC, PD_VO and PD_VPU power domains. However, one I2C controller belong to an undescribed always powered on power domain. Add support to describe an optional power-domains for the I2C controllers in Rockchip SoCs.

Use guard to automatically release the lock after going out of scope instead of calling it manually. i2c_imx_slave_handle() can safely be entered with the lock held. Refactored the i2c_imx_isr function so that i2c_imx_master_isr does not participate in the guard scope So Using scoped_guard simplifies the control flow by ensuring consistent and automatic unlock, which improves readability without affecting correctness.

Add support for the Renesas RZ/T2H (R9A09G077) SoC, which features a different interrupt layout for the RIIC controller. Unlike other SoCs with individual error interrupts, RZ/T2H uses a combined error interrupt (EEI). Introduce a new IRQ descriptor table for RZ/T2H, along with a custom ISR (`riic_eei_isr`) to handle STOP and NACK detection from the shared interrupt.

In preparation for adding support for Renesas RZ/T2H and RZ/N2H SoCs, which feature a combined error interrupt instead of individual error interrupts per condition, update the driver to support configurable IRQ layouts via OF data. Introduce a new `irqs` field and `num_irqs` count in `riic_of_data` to allow future SoCs to provide a custom IRQ layout.

Document support for the I2C Bus Interface (RIIC) found on the Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs. The RIIC IP on these parts is similar to that on RZ/V2H(P) but supports only four interrupts (including a combined error/event), lacks FM+ mode, and does not require reset. Introduce a new compatible string `renesas,riic-r9a09g077` for RZ/T2H and use it as a fallback for RZ/N2H. Unlike earlier SoCs that use eight distinct interrupts, the RZ/T2H uses only four. Update the binding schema to reflect this interrupt layout and skip the `resets` property check, as it is not required on these SoCs.

But when loading modules that have trace events, the addition of the events are not protected by the semaphore and loading two modules that have events at the same time can corrupt the list.

2025-07-19tracing: Add down_write(trace_event_sem) when adding trace eventSteven Rostedt
When a module is loaded, it adds trace events defined by the module. It may also need to modify the modules trace printk formats to replace enum names with their values. If two modules are loaded at the same time, the adding of the event to the ftrace_events list can corrupt the walking of the list in the code that is modifying the printk format strings and crash the kernel. The addition of the event should take the trace_event_sem for write while it adds the new event. Also add a lockdep_assert_held() on that semaphore in __trace_add_event_dirs() as it iterates the list.

At the time of the memcpy, entry->size contains garbage from the ringbuffer, which under some circumstances is zero, triggering a kernel panic by buffer overflow. Populate the size field before the memcpy so that the out-of-bounds check knows the correct size. This is analogous to __ftrace_trace_stack().
