X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0b1aa90e2d6ccb8ce7530f3a15426939871e1c07;p=thirdparty%2Fkernel%2Fstable.git

ARM: dts: stm32: add iwdg1 node in stm32mp131.dtsi

Add the IWDG1 node in the stm32mp131.dtsi SoC device tree file. It can
be used by Linux as the Cortex-A7 watchdog when it's configured as
non-secure.
