Subject: [PATCH 0/2] Add support for Azoteq IQS626A
Date: Sun, 22 Nov 2020 16:39:06 -0600 [thread overview]
Message-ID: <1606084748-4097-1-git-send-email-jeff@labundy.com> (raw)
This series introduces support for the Azoteq IQS626A capacitive touch
controller, a highly flexible multifunction sensor targeting wearable
applications. It is a close cousin to the IQS269A with the following key
differences:
- Channel count increases from 8 to 14.
- Channels are assigned dedicated functions as follows:
- ULP (ultra-low power): a single channel that continues to be sampled
during the device's lowest-power sensing mode for wake-up signaling.
- Trackpad: a group of 6 or 9 channels forming a capacitive trackpad with
gesture support.
- Generic: 3 independent channels capable of capacitive or inductive
sensing, plus much more.
- Hall: a single channel leveraging a pair of internal Hall-effect plates
serving lid or dock detection.
- Each channel (or group of channels) has a unique collection of configurable
parameters rather than common parameters for every channel.
Channels and events reported by the channels are configured using the device
tree, similar to what was done for the IQS269A.
A demo is shown in the following video: https://youtu.be/n0Q5BXYFIgI
