Support for applying a device tree overlay to the barebox live tree
is already present. This series adds a few missing pieces:
- add support for applying overlays to the live tree from the command
line
- add support for adding new I2C/SPI devices via overlays
- add Makefile magic to build dtbo files and dtbo.o files to include
into the barebox binary from dtso files
Changes since v1:
- add a device_rescan() static inline wrapper
- add missing call to of_i2c_register_devices() in i2c_add_numbered_adapter()
- replace device_detect with device_rescan in of_device_create_on_demand()
Sascha Hauer (7):
kbuild: Add target to build dtb overlay files
driver: Add rescan hook to struct device
i2c: implement rescan
spi: Directly register SPI device
spi: reduce scope of 'chip'
spi: implement rescan
of_overlay: Add option to apply overlay to live tree
