This supports the Cirque Pinnacle 1CA027 Touch Controller, which is used in the TM040040, TM035035 and the TM023023 trackpads. These are I2C or SPI compatible, and both configurations are supported.

**`CIRQUE_PINNACLE_ATTENUATION`** is a measure of how much data is suppressed in regards to sensitivity. The higher the attenuation, the less sensitive the touchpad will be.

Default Scaling/CPI is 1024.

Also see the `POINTING_DEVICE_TASK_THROTTLE_MS`, which defaults to 10ms when using Cirque Pinnacle, which matches the internal update rate of the position registers (in standard configuration). Advanced configuration for pen/stylus usage might require lower values.
