2026-05-31iio: magnetometer: ak8975: fix wrong errno on returnJoshua Crofts
The driver currently returns -EINVAL on polling timeout instead of -ETIMEDOUT. Replace return code for -ETIMEDOUT and remove unnecessary error message as -ETIMEDOUT is a standard POSIX error. Also replace instances of -EINVAL in comments.

Replace mutex_lock() and mutex_unlock() calls in rm3100-core.c with the more modern guard(mutex)() family. This will help modernize the driver and bring it up-to-date with modern available macros/functions. While replacing mutex_lock() and mutex_unlock(), the critical sections of rm3100_read_mag() and rm3100_get_samp_freq() have been extended to include negligible operations for cleaner logic. Add new helper-wrapper function rm3100_regmap_bulk_read_locked() to help keep rm3100_trigger_handler() switch-cases clean while maintaining mutex locking and avoiding re-entrancy risks from potential callbacks. While at it, remove redundant gotos where applicable, and use direct returns instead. In addition, remove regmap variable in rm3100_trigger_handler() as its references have been replaced with variable data.

2026-05-31iio: light: si1133: prevent race condition on timeoutJoshua Crofts
Sashiko reported a bug where the si1133_command exits on timeout without halting the sensor or masking the interrupt. If the sensor completes the command later, any subsequent command to the sensor will cause the IRQ handler to complete immediately, returning stale data to the driver all while the command hasn't finished yet, shifting all potential reads in the future. Fix this by masking the IRQ if wait_for_completion_timeout() fails. When initiating a new command, do a dummy read of the IRQ_STATUS register and turn the IRQ back on.

Sashiko reported a potential race condition happening when the driver returns an errno after a timeout in the si1133_command() function. The premature exit causes the hardware and software counters to become out of sync by not updating data->rsp_seq, therefore the internal hardware counter keeps incrementing. Fix this by adding a call to si1133_cmd_reset_counter() before returning from timeout.

2026-05-31arm64: dts: renesas: r9a08g046l48-smarc: Add gpio keysBiju Das
RZ/G3L SMARC EVK has 3 user buttons called USER_SW1, USER_SW2 and USER_SW3. Instantiate the gpio-keys driver for these buttons by removing place holders and replacing proper pins for the buttons. USER_SW{1,2,3} are configured as wakeup-sources, so they can wake up the system during s2idle.

2026-05-31arm64: dts: renesas: rzt2h-n2h-evk: Enable xSPI nodesLad Prabhakar
Enable the xSPI0 and xSPI1 controllers on the RZ/T2H N2H EVK board. Configure the xSPI0 controller interface to 1-bit (x1) mode, even though the connected MX25LW51245 octal flash device supports octal mode. Add a corresponding inline hardware comment detailing this restriction; operating in octal mode causes the BootROM to fail loading the first-stage bootloader following a Watchdog Timer (WDT) reset. Configure the xSPI1 controller interface connected to the AT25SF128A flash device for 4-bit (x4) mode to utilize all available data lines.
