Subject: [PATCH v6 3/7] mfd: Add new driver for MAX77705 PMIC
Add the core MFD driver for max77705 PMIC. We define five sub-devices
for which the drivers will be added in subsequent patches.
Signed-off-by: Dzmitry Sankouski <dsankouski@...il.com>
---
Changes for v5:
- license change to 2.0
- use same hardware name in Kconfig and module descriptions
Changes for v4:
- rework driver from scratch
- migrate to regmap_add_irq_chip, remove max77705-irq.c,
rename max77705-core.c to max77705.c
- cleanup headers
- remove debugfs code
- migrate to use max77693_dev structure
- remove max77705.h
