leds: simatic-ipc-leds-gpio: Add Elkhart Lake version
...
This is used for the Siemens Simatic IPC BX-21A, which has its LEDs
connected to GPIOs provided by the Intel Elkhart Lake pinctrl driver.

leds: simatic-ipc-leds-gpio: Introduce more Kconfig switches
...
To describe the dependency chain better and allow for potential
fine-grained config tuning, introduce Kconfig switch for the individual
GPIO based drivers.

leds: simatic-ipc-leds-gpio: Split up into multiple drivers
...
In order to clearly describe the dependencies between the GPIO
controller drivers and the users the driver is split up into a core,
two drivers and a common header.

leds: simatic-ipc-leds-gpio: Add GPIO version of Siemens driver
...
On Apollo Lake the pinctrl drivers will now come up without ACPI. Use
that instead of open coding it.
Create a new driver for that which can later be filled with more GPIO
based models, and which has different dependencies.

leds: simatic-ipc-leds: add new driver for Siemens Industial PCs
...
This driver adds initial support for several devices from Siemens. It is
based on a platform driver introduced in an earlier commit.
One of the supported machines has GPIO connected LEDs, here we poke GPIO
memory directly because pinctrl does not come up.
