X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d4dd78de95a5f773e3146c9d6cb05f91ff85c7f4;p=thirdparty%2Fkernel%2Flinux.git

arm: dts: stm32: enable the debug bus on stm32mp1x boards

On stm32mp1x boards, enable the debug bus so we always try to probe
the debug peripherals, if their status and the debug configuration
allow it.
