Subject: [PATCH v6 07/12] arm64: dts: qcom: sdm845-starqltechn: add
 max77705 PMIC

Add support for max77705 MFD device. Supported sub-devices:
 charger, fuelgauge, haptic, led

Signed-off-by: Dzmitry Sankouski <dsankouski@...il.com>
---
Changes in v6:
- refactor: s/starqltechn/sdm845-starqltechn in subject
- refactor: 'm' < 's', so putting motor tlmm nodes first

Changes in v5:
- fix according to binding changes
- reorder vib_pwm node
