Create the class, character device and functions for a fwctl driver to un/register to the subsystem. A typical fwctl driver has a sysfs presence like: $ ls -l /dev/fwctl/fwctl0 crw------- 1 root root 250, 0 Apr 25 19:16 /dev/fwctl/fwctl0 $ ls /sys/class/fwctl/fwctl0 dev device power subsystem uevent $ ls /sys/class/fwctl/fwctl0/device/infiniband/ ibp0s10f0 $ ls /sys/class/infiniband/ibp0s10f0/device/fwctl/ fwctl0/ $ ls /sys/devices/pci0000:00/0000:00:0a.0/fwctl/fwctl0 dev device power subsystem uevent Which allows userspace to link all the multi-subsystem driver components together and learn the subsystem specific names for the device's components.

GPIO must come after pinctrl as gpios may need to mux pins etc
obj-$(CONFIG_PINCTRL) += pinctrl/ obj-$(CONFIG_GPIOLIB) += gpio/ obj-y += pwm/
LEDs must come before PCI, it is needed by NPEM driver

IPMI must come before ACPI in order to provide IPMI opregion support

PnP must come after ACPI since it will eventually need to check if acpi
was used and do nothing if so

Many drivers will want to use DMA so this has to be made available
really early.

regulators early, since some subsystems rely on them to initialize

reset controllers early, since gpu drivers might rely on them to initialize
obj-$(CONFIG_RESET_CONTROLLER) += reset/
tty/ comes before char/ so that the VT console is the boot-time
default.

iommu/ comes before gpu as gpu are using iommu controllers

gpu/ comes after char for AGP vs DRM startup and after iommu
