Merge tag 'soc-arm-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Arnd Bergmann:
 "The SoC specific code updates for 6.13 are fairly minimal.

  One Broadcom SoC model gains automatic configuration for the debug
  uarg as we have on many other machines, the remaining changes are
  trivial cleanups"

* tag 'soc-arm-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
  ARM: imx: Switch to new sys-off handler API
  ARM: bcm: brcmstb: Drop custom init_irq callback
  ARM: bcm: Support BCMBCA debug UART
  ARM: zynq: Remove unused zynq_slcr_init() declaration
  ASoC: samsung: Remove obsoleted declaration for s3c64xx_ac97_setup_gpio
  ARM: samsung: Remove obsoleted declaration for s3c_hwmon_set_platdata
