leds: simatic-ipc-leds: default config switch to platform switch

2023-07-31T10:35:16+00:00

If a user did choose to enable Siemens Simatic platform support they likely want the LED drivers to be enabled without having to flip more config switches. So we make the LED drivers config switch default to the platform driver switches value.

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. Signed-off-by: Henning Schild Link: https://lore.kernel.org/r/20230713115639.16419-3-henning.schild@siemens.com Signed-off-by: Lee Jones

leds: simatic-ipc-leds-gpio: Restore LEDS_CLASS dependency

2023-07-28T08:26:19+00:00

A recent rework accidentally lost the dependency on LEDS_CLASS, which leads to a link error when LED support is disbled: x86_64-linux-ld: drivers/leds/simple/simatic-ipc-leds.o: in function `simatic_ipc_leds_probe': simatic-ipc-leds.c:(.text+0x10c): undefined reference to `devm_led_classdev_register_ext' Add back the dependency that was there originally.

leds: simatic-ipc-leds-gpio: Introduce more Kconfig switches

2023-06-08T17:29:47+00:00

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: Add GPIO version of Siemens driver

2022-07-14T09:50:43+00:00

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: Convert to use P2SB accessor

2022-07-14T09:50:36+00:00

Since we have a common P2SB accessor in tree we may use it instead of open coded variants. Replace custom code by p2sb_bar() call. Signed-off-by: Henning Schild Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

leds: simatic-ipc-leds: add new driver for Siemens Industial PCs

2021-12-23T17:09:13+00:00

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.
