Watchdog has limitations since it 44 cannot interrupt same or higher priorities so it cannot fully replace 45 hardware based watchdog. 46 47if WDT_COUNTER 48 49config WDT_COUNTER_CH_COUNT 50 int "Maximum number of supported channel" 51 default 4 52 range 1 255 53 help 54 Note that actual channel count will be limited to number of channels 55 supported by the counter device which is used for watchdog. 56 57endif # WDT_COUNTER 58 59source "drivers/watchdog/Kconfig.stm32" 60 61source "drivers/watchdog/Kconfig.cmsdk_apb" 62 63source "drivers/watchdog/Kconfig.sam" 64 65source "drivers/watchdog/Kconfig.esp32" 66 67source "drivers/watchdog/Kconfig.sam0" 68 69source "drivers/watchdog/Kconfig.nrfx" 70 71source "drivers/watchdog/Kconfig.mcux" 72 73source "drivers/watchdog/Kconfig.mcux_imx" 74 75source "drivers/watchdog/Kconfig.xec" 76 77source "drivers/watchdog/Kconfig.gecko" 78 79source "drivers/watchdog/Kconfig.sifive" 80 81source "drivers/watchdog/Kconfig.npcx" 82 83source "drivers/watchdog/Kconfig.cc32xx" 84 85source "drivers/watchdog/Kconfig.cc13xx_cc26xx" 86 87source "drivers/watchdog/Kconfig.it8xxx2" 88 89source "drivers/watchdog/Kconfig.rpi_pico" 90 91source "drivers/watchdog/Kconfig.gd32" 92 93source "drivers/watchdog/Kconfig.npm1300" 94 95source "drivers/watchdog/Kconfig.npm6001" 96 97source "drivers/watchdog/Kconfig.nxp_s32" 98 99source "drivers/watchdog/Kconfig.dw" 100 101source "drivers/watchdog/Kconfig.intel_adsp" 102 103source "drivers/watchdog/Kconfig.smartbond" 104 105source "drivers/watchdog/Kconfig.ti_tps382x" 106 107source "drivers/watchdog/Kconfig.tco" 108 109source "drivers/watchdog/Kconfig.xlnx" 110 111source "drivers/watchdog/Kconfig.ifx_cat1" 112 113source "drivers/watchdog/Kconfig.opentitan" 114 115source "drivers/watchdog/Kconfig.andes_atcwdt200" 116 117source "drivers/watchdog/Kconfig.nxp_fs26" 118 119source "drivers/watchdog/Kconfig.ambiq" 120 121source "drivers/watchdog/Kconfig.shell" 122 123endif # WATCHDOG 124
