Subject[PATCH 0/6] Add pinctrl support for Baytrail
Date
Add support for pin control (pin muxing and pin configuration) for Baytrail
platform.

It follows the design in pinctrl-intel.c, but could not use the
implementation in pinctrl-intel since there were significant differences:
- gpio pin pads are not ordered
- per group functions: for setting a certain mode, there are groups
that need setting pins with different values; for instance, for
setting USB ULPI pins to GPIO function, pin 2 (GPIO_SUS1) needs
to be set to function 1, wihle all other from the group need to be
set to 0
- communities only need pin base and count as specific data
- irq set type only clears all flags, while the actual type setting
is made in the byt_irq_unmask function, which does not comply with
the intel pinctrl implementation

Cristina Ciocan (6):
pinctrl: baytrail: Add pin control data structures
pinctrl: baytrail: Add pin control operations
pinctrl: baytrail: Update gpio chip operations
pinctrl: baytrail: Update irq chip operations
pinctrl: baytrail: Register pin control handling
pinctrl: baytrail: Add debounce configuration
