Juergen Fitschen	18e9167c73	cpu/efm32/adc: add support for Gecko Series 2 ... Series 2 features IADCs instead of ADCs.	2022-11-22 14:44:56 +01:00
Jue	54e915e40d	cpu/efm32/timer_series2: sync STATUS register ... Make sure the STATUS register has been synced between the different clock domains. Especially the LETIMER needs some time to update the STATUS register after it has been enabled. If the LETIMER is started and stopped with just a short delay, pm_layered gets confused because the timer seems to be inactive ...	2022-10-28 11:34:55 +02:00
Jue	e6d18af3ad	cpu/efm32/timer_series2: fix timer_start() interaction with pm_layered ... The timer hasn't been enabled yet, if the STATUS isn't RUNNING, yet ...	2022-10-28 11:34:55 +02:00
Juergen Fitschen	6190738bf0	cpu/efm32: include periph_conf.h for system-related methods ... This allows boards to define different crystal frequencies. The correct frequency is required by the system-related methods to ensure proper function of the underlying emlib.	2022-10-27 15:22:58 +02:00

Gunar Schorcht	550a599da9	cpu/efm32: fix RTT_MAX_VALUE selection ... EFM32GG12 have both a RTC and a RTCC. `_RTC_CNT_MAX` is used as `RTT_MAX_VALUE` in this case.	2022-10-17 08:19:08 +02:00

MrKevinWeiss	9b6036def3	cpu/efm32/periph: remove seriesn in kconfig ... As this is not handled in the makefile.dep it does not need to be modeled in kconfig.	2022-08-17 14:37:23 +02:00
Marian Buschsieweke	16f859dafd	drivers/saul: use const qualifier for data to write ... This makes life easier when calling e.g. `saul_reg_write()` with data stored in flash. As now the signatures for reading and writing differ (in that `const` qualifier only), `saul_notsup()` is split into `saul_write_notsup()` and `saul_read_notsup()`. However, one is implemented as a symbol alias of the other, so that ROM consumption remains unchanged.	2022-05-23 08:35:27 +02:00

Kevin "Tristate Tom" Weiss	ed94dd7085	Merge pull request #17376 from leandrolanzieri/pr/makefiles/add_board_cpu_config_variables ... makefiles/kconfig: add board & CPU config variables	2021-12-13 13:26:40 +01:00
Leandro Lanzieri	df7ce1c647	makefiles/kconfig: use two lists for boards and CPUs default configs ... This introduces KCONFIG_BOARD_CONFIG and KCONFIG_CPU_CONFIG variable for boards and CPUs (including common directories) to add default configuration files to be merged. The current approach, as it uses Makefile.features, would include boards first, not allowing them to override CPU configurations.	2021-12-13 12:33:21 +01:00

Benjamin Valentin	d47a880915	cpu: add periph_rtt_overflow feature ... The RTT overflow callback is not available on all RTT implementations. This means it is either a no-op or `rtt_set_overflow_cb()` is a no-op or it will overwrite the alarm set with `rtt_set_alarm()`. This adds a feature to indicate that proper overflow reporting is available.	2021-04-30 11:58:00 +02:00

Marian Buschsieweke	ab89234040	drivers/periph/rtt: add periph_rtt_set_counter feature ... Some periph_rtt implementations do not provide `rtt_set_counter()`. This adds `periph_rtt_set_counter` as feature to allow testing for its availability. The feature is provided at CPU level if periph_rtt is provided by the board for all CPUs implementing `rtt_set_counter()`.	2021-03-08 14:16:46 +01:00
