CAP1114 is a 14-channel capacitive touch sensor with 11 LED outputs
and hardware reset support.
Patches 1-4 perform driver cleanup and DT binding tweaks.
Patches 5-6 add reset-gpios support for CAP11xx.
Patches 7-10 add support for CAP1114.
Changes in v3:
- Simplified the logic of the reset pin operation.
- Adjust linux,keycodes configuration for CAP11xx.
- Drop unnecessary CAP11XX_REG_SENSOR_THRESH(8).
- Checks for the presence of microchip,calib-sensitivity and
microchip,signal-guard properties before processing them.
- Link to v2:

Changes in v2:
- Drop LED property tweaks, keep only reg changes and node regex
update in DT bindings.
- Split microchip,cap1126 LED reg constraints into a separate patch.
- Replace usleep_range() with msleep() for 500 ms delay during
reset pin handling.
- Add missing <linux/delay.h> for usleep_range() and msleep().
- Add CAP1114 to unsupported enum for microchip,signal-guard and
microchip,calib-sensitivity
- Add constraint for linux,keycodes to support CAP1114.
- When reading CAP1114 button status, mask STATUS1 to bits 0-5
and OR with STATUS2.
- Adjust code style.
