Subject: [PATCH 6/6] arm64: dts: st: Add boot phase tags for
STMicroelectronics mp2 boards
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.
Signed-off-by: Patrice Chotard <patrice.chotard@...s.st.com>
