PCIe defines two optional hotplug indicators: a Power indicator and an
Attention indicator. Both are controlled by the same register, and each
can be on, off or blinking. The current interfaces
(pciehp_green_led_{on,off,blink}() and pciehp_set_attention_status()) are
non-uniform and require two register writes in many cases where we could
do one.

This patchset introduces the new function pciehp_set_indicators(). It
allows one to set two indicators with a single register write. All
calls to previous interfaces (pciehp_green_led_* and
pciehp_set_attention_status()) are replaced with a new one.

Denis Efremov (4):
  PCI: pciehp: Add pciehp_set_indicators() to jointly set LED indicators
  PCI: pciehp: Switch LED indicators with a single write
  PCI: pciehp: Replace pciehp_set_attention_status()
  PCI: pciehp: Replace pciehp_green_led_{on,off,blink}()
