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

2021-12-23T17:09:13Z

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.
