[PATCH 2/4] ARM: dts: stm32: Use hex timer addresses on stm32mp15
From: Fabrice Gasnier
Date: Mon Nov 09 2026 - 11:31:43 EST
Use hexadecimal unit addresses for timer subnodes. This has been raised
since ("dt-bindings: Use hex unit address patterns").
Also:
- adopt hexadecimal format for reg properties.
- update MP15 boards accordingly as they use timers 12 and 17.
