Add pciehp_set_indicators() to set power and attention indicators with a single register write. This is a minor optimization because we frequently set both indicators and this can do it with a single command. It also reduces the number of interfaces related to the indicators and makes them more discoverable because callers use the PCI_EXP_SLTCTL_ATTN_IND_* and PCI_EXP_SLTCTL_PWR_IND_* definitions directly. [bhelgaas: extend commit log, s/PCI_EXP_SLTCTL_.*_IND_NONE/INDICATOR_NOOP/ so they don't look like things defined by the spec, add function doc, mask commands to make it obvious we only send valid commands (pcie_do_write_cmd() does mask it, but requires more effort to verify)] Link: https://lore.kernel.org/r/20190903111021.1559-2-efremov@linux.com Signed-off-by: Denis Efremov <efremov@linux.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |
