Subject: [PATCH 1/3] dt-bindings: spi: st,stm32-spi: add 'power-domains' property
Date: Mon, 15 Dec 2025 13:26:20 +0100 [thread overview]
Message-ID: <20251215-stm32-spi-mp2x-dt-updates-v1-1-464a5fd20f13@foss.st.com> (raw)
In-Reply-To: <20251215-stm32-spi-mp2x-dt-updates-v1-0-464a5fd20f13@foss.st.com>
STM32 SPI may be in a power domain which is the case for the STM32MP2x
based boards. Allow a single 'power-domains' entry for STM32 SPI.
