parisc/power: Fix power soft-off button emulation on qemu

2024-02-01T00:18:52+00:00

commit 6472036581f947109b20664121db1d143e916f0b upstream. Make sure to start the kthread to check the power button on qemu as well if the power button address was provided. This fixes the qemu built-in system_powerdown runtime command.

parisc/power: Fix power soft-off when running on qemu

2023-11-28T17:20:08+00:00

commit 6ad6e15a9c46b8f0932cd99724f26f3db4db1cdf upstream. Firmware returns the physical address of the power switch, so need to use gsc_writel() instead of direct memory access.

parisc: sba_iommu: Fix build warning if procfs if disabled

2023-08-31T19:42:42+00:00

Clean up the code, e.g. make proc_mckinley_root static, drop the now empty mckinley header file and remove some unneeded ifdefs around procfs functions.

parisc: ccio-dma: Create private runway procfs root entry

2023-08-28T16:00:27+00:00

Create an own procfs "runway" root entry for the CCIO driver. No need to share it with the sba_iommu driver, as only one of those busses can be active in one machine anyway.

parisc: led: Rewrite LED/LCD driver to utilizize Linux LED subsystem

2023-08-28T15:58:14+00:00

Rewrite the whole driver and drop the own code to calculate load average, disk and LAN load. Switch instead to use the in-kernel LED subsystem, which gives us quite some advantages, e.g. - existing triggers for heartbeat and disk/lan activity can be used - users can configre the LEDs at will to any existing trigger via /sys/class/leds - less overhead since we don't need to run own timers - fully integrated in Linux and as such cleaner code. Note that the driver now depends on CONFIG_LEDS_CLASS which has to be built-in and not as module. Signed-off-by: Helge Deller

parisc: lasi: Initialize LASI driver via arch_initcall()

2023-08-27T09:09:10+00:00

Move initialization code for LASI out of the GSC driver. Since ASP and WAX have been moved in previous commits, the GSC driver is now just a driver which provides library functions for LASI, ASP and WAX and as such doesn't need an own initialization function any longer. Signed-off-by: Helge Deller
