Subject: [PATCH 2/2] spi: spi-stm32-ospi: Make "resets" a required property
Date: Fri, 21 Mar 2025 10:44:07 +0100 [thread overview]
Message-ID: <20250321-upstream_ospi_required_resets-v1-2-9aa4702e3ae2@foss.st.com> (raw)
In-Reply-To: <20250321-upstream_ospi_required_resets-v1-0-9aa4702e3ae2@foss.st.com>
On some STM32MP2 SoCs, an Octo Memory Manager is embedded and
need to retrieve OSPI's reset to perform its own initialization.
Make "resets" property mandatory.
Fixes: 79b8a705e26c ("spi: stm32: Add OSPI driver")
