This patchset adds support for gpio-uclass to work with pmic gpio childrens properly and implements MAX77663 and PALMAS GPIO cells/children as a reference and to be further used in devices I am currently maintaining.
All drivers are tested on actual hardware and confirmed to work as expected. MAX77663 GPIO cell is tested on wexler qc750 tegra 3 device and PALMAS GPIO cell is tested on tegra note 7 tegra 4 device.
--- Changes from v1: - isolate PMIC GPIO cells parsing behind enabling DM_PMIC ---
