[U-Boot] [PATCH v1 3/9] ARM: dts: stm32: Migrate U-boot nodes to U-boot DT files for stm32f7
Patrice Chotard
patrice.chotard at st.com
Fri Feb 22 14:00:10 UTC 2019
In order to prepare and ease future DT synchronization with kernel
DT, migrate all U-boot specific nodes/properties/addons to
U-boot DT files.
Migrate also DT nodes which are not yet available on kernel DT side
as ethernet, ltdc and qspi nodes.
Fix ethernet_mii pins and add missing qspi_pins for stm32746g-eval
