13 The Azoteq IQS269A is an 8-channel capacitive touch controller that features
14 additional Hall-effect and inductive sensing capabilities.

34 azoteq,hall-enable:
37 Enables Hall-effect sensing on channels 6 and 7. In this case, keycodes
39 interpreted as switch codes. Refer to the datasheet for requirements im-
40 posed on channels 6 and 7 by Hall-effect sensing.

117 azoteq,timeout-pwr-ms:
123 Specifies the length of time (in ms) to wait for an event during normal-
124 power mode before transitioning to low-power mode.
126 azoteq,timeout-lta-ms:
132 Specifies the length of time (in ms) to wait before resetting the long-
133 term average of all channels. Specify the maximum timeout to disable it
