PCI: hotplug: Add Ampere Altra Attention Indicator extension driver On Ampere Altra, PCIe hotplug is handled through ACPI. A side interface is also present to request system firmware control of the hotplug Attention Indicators. Add an ACPI PCI Hotplug companion driver to support Attention Indicator control.

treewide: replace '---help---' in Kconfig files with 'help' Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

PCI/hotplug: PowerPC PowerNV PCI hotplug driver This adds standalone driver to support PCI hotplug for PowerPC PowerNV platform that runs on top of skiboot firmware. The firmware identifies hotpluggable slots and marked their device tree node with proper "ibm,slot-pluggable" and "ibm,reset-by-firmware". The driver scans device tree nodes to create/register PCI hotplug slot accordingly. The PCI slots are organized in fashion of tree, which means one PCI slot might have parent PCI slot and parent PCI slot possibly contains multiple child PCI slots. At the plugging time, the parent PCI slot is populated before its children. The child PCI slots are removed before their parent PCI slot can be removed from the system. If the skiboot firmware doesn't support slot status retrieval, the PCI slot device node shouldn't have property "ibm,reset-by-firmware". In that case, none of valid PCI slots will be detected from device tree. The skiboot firmware doesn't export the capability to access attention LEDs yet and it's something for TBD.

s390/pci: PCI hotplug support via SCLP Add SCLP PCI configure/deconfigure and implement a PCI hotplug controller (s390_pci_hpc). The hotplug controller creates a slot for every PCI function in stand-by or configured state. The PCI functions are named after the PCI function ID (fid). By writing to the power attribute in /sys/bus/pci/slots/<fid>/power the PCI function is moved to stand-by or configured state. If moved to the configured state the device is automatically scanned by the s390 PCI layer.

PCI Hotplug: cpqphp: don't use pci_find_slot() Convert uses of pci_find_slot to modern API. In the conversion sites, we end up calling pci_dev_put() right away. This may seem like it misses the entire point of doing something like pci_get_bus_and_slot(), since we drop the reference so soon, but it turns out we don't actually do much with the returned pci_dev. I plan on untangling cpqphp further, but clearly cpqphp never worried too much about a properly refcounted pci_dev anyway. For now, this conversion seems reasonable, as it gets rid of the last in-tree caller of pci_find_slot.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
