[PATCH 00/31] Add domain idle state names

[Maulik Shah]

Add or update idle-state-name properties for Qualcomm CPU and domain idle
states.

The generic cpuidle parser can fall back to the DT node name for CPU idle
state descriptions, but genpd domain idle states do not get an implicit
fallback name. Without an idle-state-name property, those genpd states are
shown as N/A in debugfs.

For example, before this change a platform may show:

  # cat /sys/kernel/debug/pm_genpd/power-domain-cluster/idle_states_desc
  State  Latency(us)  Residency(us)  Name
  S0     5790         6118           N/A

With an idle-state-name property in DT, the same state is reported with a
proper low power mode name:

  # cat /sys/kernel/debug/pm_genpd/power-domain-cluster/idle_states_desc
  State  Latency(us)  Residency(us)  Name
  S0     5800         6118           l3-pc

Describe the affected low power modes explicitly so the CPU and domain idle
states are reported consistently across Qualcomm platforms. Shorten
existing power-collapse and power-down names to use pc.

Most Qualcomm silver CPU idle states do not turn the silver rail off;
they collapse the CPU and turn the PLL off. Name those states
silver-pll-pc. Gold CPU states often turn both PLL and rail off, so use
gold-pll-rail-pc to reflect the low power mode.
