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

2023-11-28T17:15:10Z

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

[ Upstream commit 6428bc7bd3f35e43c8cb7359cb89d83248d339d2 ] 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: led: Reduce CPU overhead for disk & lan LED computation

2023-09-19T10:30:11Z

commit 358ad816e52d4253b38c2f312e6b1cbd89e0dbf7 upstream. Older PA-RISC machines have LEDs which show the disk- and LAN-activity. The computation is done in software and takes quite some time, e.g. on a J6500 this may take up to 60% time of one CPU if the machine is loaded via network traffic. Since most people don't care about the LEDs, start with LEDs disabled and just show a CPU heartbeat LED. The disk and LAN LEDs can be turned on manually via /proc/pdc/led.

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

2023-09-13T07:53:49Z

commit 77e0ddf097d6d4ceaf898e088b133b99e0a97fa0 upstream. 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.
