Subject: [PATCH 4/4] arm64: dts: stm32: Use hex timer addresses on stm32mp251
Date: Mon, 9 Nov 2026 17:25:06 +0100 [thread overview]
Message-ID: <20261109-timer-use-hex-unit-addr-v1-4-b4abfa457adb@foss.st.com> (raw)
In-Reply-To: <20261109-timer-use-hex-unit-addr-v1-0-b4abfa457adb@foss.st.com>
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 stm32mp257f-ev1 board accordingly as it uses timer 12.
