Proof of Concept only - not for merging. The following patch set is a minimal conversion of two ColdFire platforms from using the legacy style platform device configuration to using a devicetree. The two platform types supported here are one each of a full MMU target (M5475EVB) and nommu (M5208EVB). It takes a few short cuts (that is hacks) to prove it is possible and show how it can be done. The problems and more work required include: . proper conversion to use clock framework . proper resource setup for interrupt controllers . conversion of more ColdFire peripherals to use devicetree . cleanup of changes for sending to appropriate lists/maintainers Signed-off-by: Greg Ungerer <gerg@xxxxxxxxxxxxxx> --- arch/m68k/Kconfig.cpu | 1 arch/m68k/boot/dts/Makefile | 1 arch/m68k/coldfire/device.c | 4 b/Documentation/devicetree/bindings/net/fsl,fec.yaml | 1 b/arch/m68k/Kconfig | 2 b/arch/m68k/Kconfig.cpu | 2 b/arch/m68k/Kconfig.devices | 11 b/arch/m68k/boot/dts/Makefile | 4 b/arch/m68k/boot/dts/mcf5208evb.dts | 57 ++++ b/arch/m68k/boot/dts/mcf5475evb.dts | 55 ++++ b/arch/m68k/coldfire/clk.c | 8 b/arch/m68k/coldfire/device.c | 221 ++++++++++++++++--- b/arch/m68k/coldfire/intc-2.c | 59 ++++- b/arch/m68k/coldfire/intc-simr.c | 61 ++++- b/arch/m68k/coldfire/intc.c | 50 +++- b/arch/m68k/include/asm/mcfuart.h | 12 - b/arch/m68k/kernel/Makefile | 1 b/arch/m68k/kernel/embedded_dtb.S | 19 + b/arch/m68k/kernel/setup_mm.c | 33 ++ b/arch/m68k/kernel/setup_no.c | 33 ++ b/arch/m68k/kernel/vmlinux-nommu.lds | 9 b/arch/m68k/kernel/vmlinux-std.lds | 10 b/drivers/net/ethernet/freescale/fec_main.c | 5 b/drivers/tty/serial/mcf.c | 49 ++-- drivers/tty/serial/mcf.c | 12 + 25 files changed, 627 insertions(+), 93 deletions(-)
