Wolfgang Wallner 5a9d7f9c91 x86: p2sb: Drop 'apl' prefix
Drop the Apollo Lake prefix 'apl' from the functions, types and
variables in the P2SB driver.

The P2SB is not Apollo Lake specific, and as such it was moved in
commit 2999846c11 ("x86: Move P2SB from Apollo Lake to a more generic
location") from the Apollo Lake folder to the intel_common folder.

* Intel Apollo Lake pin controller
The Apollo Lake (APL) pin controller is used to select the function of a pin
and to configure it.
Required properties:
- compatible: "intel,apl-pinctrl"
- intel,p2sb-port-id: Port ID number within the parent P2SB
- reg: PCI address of the controller
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices.
Optional subnodes:
GPIO nodes may be added as children of the pinctrl nodes. See intel,apl-gpio
for the binding.
Example:
...
{
p2sb: p2sb@d,0 {
reg = <0x02006810 0 0 0 0>;
compatible = "intel,p2sb";
early-regs = <IOMAP_P2SB_BAR 0x100000>;
n {
compatible = "intel,apl-pinctrl";
intel,p2sb-port-id = <PID_GPIO_N>;
gpio_n: gpio-n {
compatible = "intel,apl-gpio";
#gpio-cells = <2>;
};
};
};
};
...
