leds: simatic-ipc-leds-gpio: fix incorrect LED to GPIO mapping

2022-10-24T09:32:10Z

For apollolake the mapping between LEDs and GPIO pins was off because of a refactoring when we introduced a new device model. In addition to the reordering the indices in the lookup table need to be updated as well.

leds: simatic-ipc-leds-gpio: add new model 227G

2022-09-01T14:14:49Z

This adds support of the Siemens Simatic IPC227G. Its LEDs are connected to GPIO pins provided by the gpio-f7188x module. We make sure that gets loaded, if not enabled in the kernel config no LED support will be available.

leds: simatic-ipc-leds-gpio: Add GPIO version of Siemens driver

2022-07-14T09:50:43Z

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

2022-07-14T09:50:36Z

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

2021-12-23T17:09:13Z

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.
