[PATCH v3 5/6] ARM: dts: stm32: Add boot phase tags for STMicroelectronics mp15 boards

Patrice Chotard posted 6 patches 1 month ago
There is a newer version of this series
[PATCH v3 5/6] ARM: dts: stm32: Add boot phase tags for STMicroelectronics mp15 boards
Posted by Patrice Chotard 1 month ago 
The bootph-all flag was introduced in dt-schema
(dtschema/schemas/bootph.yaml) to define node usage across
different boot phases.

To ensure SD boot, timer, gpio, syscfg, clock and uart nodes need to be
present in all boot stages, so add missing bootph-all phase flag
to these nodes to support SD boot.
