config COUNTER_SILABS_PROTIMER
	bool "Silicon Labs PROTIMER Counter driver"
	default y
	depends on SOC_FAMILY_SILABS_S2
	depends on DT_HAS_SILABS_PROTIMER_ENABLED
	depends on BUILD_ONLY_NO_BLOBS || \
		(ZEPHYR_HAL_SILABS_MODULE_BLOBS && SOC_GECKO_USE_RAIL)
	help
	  Enable counter driver for Silicon Labs PROTIMER peripheral which
	  is used as the RAIL timer. With BUILD_ONLY_NO_BLOBS (e.g. twister builds),
	  non-functional stubs are used and the driver will not work on device.
	  When built with RAIL blobs, SOC_GECKO_USE_RAIL must be
	  enabled and RAIL must be initialized first. The PROTIMER lives
	  in the radio block and its clock is not enabled until RAIL init.


config COUNTER_GECKO_RTCC
	bool "Silicon Labs Gecko Counter (RTCC) driver"
	default y
	depends on DT_HAS_SILABS_GECKO_RTCC_ENABLED
	select SOC_GECKO_CMU
	select SOC_GECKO_RTCC
	help
	  Enable counter driver based on RTCC module for Silicon Labs Gecko
	  chips.

config COUNTER_GECKO_STIMER
	bool "Silicon Labs Gecko Counter Sleep Timer driver"
	default y
	depends on $(dt_chosen_enabled,$(DT_CHOSEN_SILABS_SLEEPTIMER))
	select SILABS_SISDK_SLEEPTIMER
	help
	  Enable the counter driver for Sleep Timer module for Silicon Labs
	  Gecko chips.

config COUNTER_SILABS_BURTC
	bool "Silicon Labs Counter Backup Timer (BURTC) driver"
	default y
	depends on DT_HAS_SILABS_BURTC_COUNTER_ENABLED
	select SILABS_SISDK_BURTC
	help
	  Enable the counter driver for Backup Real Time Counter module
	  for Silicon Labs chips.

config COUNTER_SILABS_BURTC_ALARM
	bool "BURTC alarm support"
	default y
	depends on COUNTER_SILABS_BURTC
	help
	  BURTC is a commonly used wake-up source for many Silabs MCUs and
	  may be used as the companion low-power timer for the Cortex-M
	  systick. Enabling single-shot alarm support requires reprogramming
	  the hardware compare register (COMP), which is the same
	  resource used for the periodic TOP callback. Because of this
	  hardware limitation, this Kconfig option selects whether alarm
	  support is enabled. When alarm support is enabled the driver will
	  not allow set TOP operation at runtime (attempts to set TOP will
	  return -ENOTSUP); When alarm support is disabled the driver will
	  not allow set and cancel ALARM operation at runtime (attempts to
	  set and cancel ALARM will return -ENOTSUP). Choose the configuration
	  that matches your application's requirements.

config COUNTER_SILABS_TIMER
	bool "Silicon Labs Series 2 TIMER Counter driver"
	default y
	depends on DT_HAS_SILABS_TIMER_COUNTER_ENABLED
	select SILABS_SISDK_TIMER
	help
	  Enable the counter driver based on the Silicon Labs
	  TIMER peripheral.
	  This driver supports counter mode with compare-match alarms
	  using TIMER on Silicon Labs Series 2 SoCs.
