Platform device instantiation (1)

• As platform devices cannot be detected dynamically, they are defined statically

• By direct instantiation of platform_device structures, as done on ARM. Definition done in the board-specific or SoC-specific code.
• By using a device tree, as done on Power PC, from which platform_device structures are created

• Example on ARM, where the instantiation is done in arch/arm/mach-imx/mx1ads.c
