PATCH v2 1/6 pinctrl: intel: Introduce common flags for GPIO mapping scheme

Few drivers are using the same flag to tell Intel pin control core how to interpret GPIO base.

Provide a generic flags so all drivers can use.

PATCH v2 5/6 pinctrl: intel: Introduce new flag to force GPIO base to be 0

In reply to Andy Shevchenko

In some cases not the first group would like to have GPIO base to be 0. It's not possible right now due to 0 has special meaning already. Thus, introduce a new flag to allow drivers to force GPIO base to be 0 on a certain group. It's assumed that it can be only one group per device with such flag enabled.

PATCH v2 6/6 pinctrl: intel: Add Intel Jasper Lake pin controller support

In reply to Andy Shevchenko

This driver adds pinctrl/GPIO support for Intel Jasper Lake SoC. The GPIO controller is based on the next generation GPIO hardware but still compatible with the one supported by the Intel core pinctrl/GPIO driver.

Re: [PATCH v2 6/6] pinctrl: intel: Add Intel Jasper Lake pin controller support

Quoted 5 lines · Andy Shevchenko

This driver adds pinctrl/GPIO support for Intel Jasper Lake SoC. The GPIO controller is based on the next generation GPIO hardware but still compatible with the one supported by the Intel core pinctrl/GPIO driver.
