pinctrl: intel: Introduce new flag to force GPIO base to be 0

2020-04-14T13:17:13+00:00

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.

pinctrl: intel: Introduce common flags for GPIO mapping scheme

2020-04-14T13:17:12+00:00

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.

pinctrl: intel: Pass irqchip when adding gpiochip

2020-01-09T11:12:20+00:00

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward conversion.

pinctrl: intel: Add GPIO <-> pin mapping ranges via callback

2020-01-09T11:12:20+00:00

When IRQ chip is instantiated via GPIO library flow, the few functions,
in particular the ACPI event registration mechanism, on some of ACPI based
platforms expect that the pin ranges are initialized to that point.

Add GPIO <-> pin mapping ranges via callback in the GPIO library flow.

pinctrl: intel: Share struct intel_pinctrl for wider use

2019-12-13T14:48:47+00:00

There are few drivers for Intel SoC GPIO which may utilize
the same data structure to describe this IP.

Share struct intel_pinctrl for wider user.

pinctrl: intel: Use GPIO direction definitions

returning GPIO direction to GPIO framework.

pinctrl: intel: Missed type change to unsigned int

2019-11-07T09:10:02+00:00

We converted 'unsigned' type to be 'unsigned int' in the driver,
but there are couple of leftovers. So, finish the task now.

pinctrl: intel: Use helper to restore register values on ->resume()

2019-10-30T14:05:18+00:00

We can restore only values that had been changed and do not spam kernel log
with unnecessary messages. Convert intel_gpio_update_pad_mode() to a helper
function that will be used across few callers.

pinctrl: intel: Drop level from warning to debug in intel_restore_hostown()

2019-10-30T14:05:18+00:00

Since we didn't get any new reports from users about wrong settings
of pad ownership, there is no point to spam kernel log with it. Thus,
drop level from warning to debug.

Also, modify format to be in align with the rest restore helpers.
