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

2022-10-24T09:32:10+00:00

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: Make simatic_ipc_led_gpio_table static

2022-09-10T12:16:16+00:00

simatic_ipc_led_gpio_table is only used inside simatic-ipc-leds-gpio.c,
make it static.

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

2022-09-01T14:14:49+00:00

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

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

leds: simatic-ipc-leds: Don't directly deref ioremap_resource() returned ptr

2022-02-17T11:25:30+00:00

Sparse (rightly) currently gives the following warning:

drivers/leds/simple/simatic-ipc-leds.c:155:40:
 sparse: sparse: incorrect type in assignment (different address spaces)
 expected void *static [toplevel] simatic_ipc_led_memory
 got void [noderef] __iomem *

Fix this by changing the type of simatic_ipc_led_memory to void __iomem *
and use readl()/writel() to access it.

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.
