Subject: pinctrl: intel: Fix 2 kOhm bias which is 833 Ohm

2 kOhm bias was never an option in Intel GPIO hardware, the available
matrix is:

	000	none
	001	1 kOhm (if available)
	010	5 kOhm
	100	20 kOhm

As easy to get the 3 resistors are gated separately and according to
parallel circuits calculations we may get combinations of the above where
the result is always strictly less than minimal resistance. Hence,
additional values can be:

	011	~833.3 Ohm
	101	~952.4 Ohm
	110	~4 kOhm
	111	~800 Ohm

That said, convert TERM definitions to be the bit masks to reflect the above.

While at it, enable the same setting for pull down case.

Subject: pinctrl: intel: Set default bias in case no particular value given

When GPIO library asks pin control to set the bias, it doesn't pass
any value of it and argument is considered boolean (and this is true
for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual
drivers must behave well, when they got the resistance value of 1 Ohm,
i.e. transforming it to sane default.

In case of Intel pin control hardware the 5 kOhm sounds plausible
because on one hand it's a minimum of resistors present in all
hardware generations and at the same time it's high enough to minimize
leakage current (will be only 200 uA with the above choice).

Subject: pinctrl: intel: Add Intel Lakefield pin controller support

This driver adds pinctrl/GPIO support for Intel Lakefield 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.

Subject: pinctrl: intel: Add Intel Elkhart Lake pin controller support

This driver adds pinctrl/GPIO support for Intel Elkhart 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.

Subject: pinctrl: intel: Add Intel Alder Lake-S pin controller support

This driver adds pinctrl/GPIO support for Intel Alder Lake-S 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.

Subject: pinctrl: lynxpoint: Use defined constant for disabled bias explicitly

We have a specific constant to describe a disabled bias,
i.e. GPIWP_NONE. Use it explicitly instead of making
an assumption about its value.

While at it, move argument assignment to the switch-case
in lp_pin_config_get().

Subject: pinctrl: lynxpoint: Enable pin configuration setting for GPIO chip

It appears that pin configuration for GPIO chip hasn't been enabled yet
due to absence of ->set_config() callback.

Enable it here for Intel Lynxpoint PCH.

Subject: pinctrl: jasperlake: Unhide SPI group of pins

If the group of pins is hidden in the pin list it affects
the register offset calculation despite fixed GPIO base.
Hence, the offsets of all pins after the hidden group
are broken. Instead we have to unhide the group and use a flag
to exclude it from GPIO number space.
