   directory as a whole to each individual driver
 - For the yaml documentation:
    * Removed json-schema dependence
    * Elaborated on description of driver
    * Updated example
 - Changed target KernelVersion in sysfs documentation
 - Updated MAINTAINER changes to be properly applied across patches
 - For the driver itself,
    * Added types.h inclusion and removed unused inclusions
    * Minor updates to code and acronym style
    * Remove __packed attribute on driver struct
    * Use .dev_groups for sysfs
 - Added more in-depth description of driver in Kconfig
 - Modified dts to reference a newly added section in sm8150.dtsi
