34Description: Reading this file gives the current selected profile for this
35 device. Writing this file with one of the strings from
36 platform_profile_choices changes the profile to the new value.

38 This file can be monitored for changes by polling for POLLPRI,
39 POLLPRI will be signaled on any changes, independent of those
40 changes coming from a userspace write; or coming from another
41 source such as e.g. a hotkey triggered profile change handled
42 either directly by the embedded-controller or fully handled
43 inside the kernel.

45 This file may also emit the string 'custom' to indicate
46 that the driver is using a driver defined custom profile.
