captouch petal 2 ghost presses
when petal 2 (reminder: only top petal controlled by the bottom chip thru very long lines) is just touched at the edge while the finger also presses petal 1 or 3 there is some ghost inputs. we could just increase threshold but that's the last resort.
possible leads:
- check electrical layout
- make custom CDC_NONE/CDC_BIAS map for the respective sequence steps
sorry it ain't much but that's all we got. it could be a top chip synchronization thing but since our current goal is 9ms top/14ms bot cycle time we can't really sync them up so let's hope it's not that.
