I tried to use fdtdump but it seems bugged. So I used directly dtc
binary to (re)generate dts files (before and after apply the series) and
I compared "pinmux" field in both case.

Example on stm32f469-disco:

./scripts/dtc/dtc -I dtb -O dts -o stm32f469-disco-after.dts
stm32f469-disco-after.dtb

./scripts/dtc/dtc -I dtb -O dts -o stm32f469-disco-before.dts
stm32f469-disco-before.dtb

cat stm32f469-disco-after.dts | grep pinmux
cat stm32f469-disco-before.dts | grep pinmux

regards
alex
