This patch adds dynamic switching to booting either with or without DT. So far only a part of the board initialisation can be done via DT. Devices, that still need platform data are kept that way. Devices, that can be initialised from DT will not be supplied from the platform data, if a DT image is detected. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> --- Hi Simon As suggested by you we drop patch #3/7 "ARM: sh7372: support mixed DT and board code interrupt controller init" and as suggested by Grant we drop patch #4/7 "ARM: sh7372: add clock lookup entries for DT-based devices" (you can drop it from your soc5 branch too now.) As a result we update this patch as follows: v2: 1. use a lookup table to still be able to use non-DT clock names (thanks to Grant for pointing out) 2. use sh7372_init_irq in the non-DT case (thanks to Simon) Patches 1, 2, 5 and 7 don't change.
