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 GPIO controller
|
|
|
|
The Apollo Lake (APL) GPIO controller is used to control GPIO functions of
|
|
the pins.
|
|
|
|
Required properties:
|
|
- compatible: "intel,apl-gpio"
|
|
- #gpio-cells: Should be 2. The syntax of the gpio specifier used by client
|
|
nodes should be the following with values derived from the SoC user manual.
|
|
<[phandle of the gpio controller node]
|
|
[pin number within the gpio controller]
|
|
[flags]>
|
|
|
|
Values for gpio specifier:
|
|
- Pin number: is a GPIO pin number between 0 and 244
|
|
- Flags: GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW
|
|
|
|
- gpio-controller: Specifies that the node is a gpio controller.
|
|
|
|
Example:
|
|
|
|
...
|
|
{
|
|
p2sb: p2sb@d,0 {
|
|
reg = <0x02006810 0 0 0 0>;
