string
help
This string holds the full part number of the SoC. It is a hidden option
that you should not set directly. The part number selection choice defines
the default value for this string.

Set the external high frequency oscillator frequency in Hz. This should be set by the
board's defconfig.

Set the external low frequency oscillator frequency in Hz. This should be set by the
board's defconfig.
config CMU_HFRCO_FREQ

default 0
depends on SOC_GECKO_HAS_HFRCO_FREQRANGE
help
Set the internal high frequency RC oscillator frequency in Hz. This should be set by the
board's defconfig. Only supported values may be used here. Setting this to 0, skips the
configuration of the high frequency RC oscillator completely. This may be desired, if
the bootloader already configured it properly or the device's default clock source should
be used with it's default configuration.

config SOC_GECKO_HAS_INDIVIDUAL_PIN_LOCATION
bool
help
If enabled, indicates that SoC allows to configure individual pin
locations. This is supported by e.g. efr32fg1p, efr32mg12p series.
If disabled, indicates that pin locations are configured in groups.
This is supported by e.g. efm32hg, efm32wg series.
config SOC_GECKO_HAS_ERRATA_RTCC_E201
bool
help
Set if the SoC is affected by errata RTCC_E201:
"When the RTCC is configured with a prescaler, the CCV1 top value enable
feature enabled by setting CCV1TOP in RTCC_CTRL fails to wrap the counter
when RTCC_CNT is equal to RTCC_CC1_CCV, as intended."
config SOC_GECKO_HAS_HFRCO_FREQRANGE
bool
help
If enabled, indicates that configuration of HFRCO frequency for this SOC is supported
via FREQRANGE field. This is supported for e.g. efr32fg1p, efr32mg12p series.
If disabled, indicates that configuration of HFRCO frequency for corresponding SOC
is not supported via this field. This is the case for e.g. efm32hg, efm32wg series.
