In order to set the AMCR register, which configures the memory-region split between ospi1 and ospi2, we need to identify the ospi instance.
By using memory-region-names, it allows to identify the ospi instance this memory-region belongs to.
Fixes: cad2492de91c ("arm64: dts: st: Add SPI NOR flash support on stm32mp257f-ev1 board") Cc: stable@vger.kernel.org Signed-off-by: Patrice Chotard patrice.chotard@foss.st.com --- Changes in v3: - Set again "Cc: stable@vger.kernel.org" - Link to v2: https://lore.kernel.org/r/20250811-upstream_fix_dts_omm-v2-1-00ff55076bd5@fo...
Changes in v2: - Update commit message. - Use correct memory-region-names value. - Remove "Cc: stable@vger.kernel.org" tag as the fixed patch is not part of a LTS. - Link to v1: https://lore.kernel.org/r/20250806-upstream_fix_dts_omm-v1-1-e68c15ed422d@fo... --- arch/arm64/boot/dts/st/stm32mp257f-ev1.dts | 1 + 1 file changed, 1 insertion(+)
