[PATCH v2 0/3] PCI: brcmstb: CLKREQ# accomodations of downstream device

[Jim Quinlan]

v2 -- Changed binding property 'brcm,completion-timeout-msec' to
      'brcm,completion-timeout-us'.  (StefanW for standard suffix).
   -- Warn when clamping timeout value, and include clamped
      region in message. Also add min and max in YAML. (StefanW)
   -- Qualify description of "brcm,completion-timeout-us" so that
      it refers to PCIe transactions. (StefanW)
   -- Remvove mention of Linux specifics in binding description. (StefanW)
   -- s/clkreq#/CLKREQ#/g (Bjorn)
   -- Refactor completion-timeout-us code to compare max and min to
      value given by the property (as opposed to the computed value).

v1 -- The current driver assumes the downstream devices can
      provide CLKREQ# for ASPM.  These commits accomodate devices
      w/ or w/o clkreq# and also handle L1SS-capable devices.

   -- The Raspian Linux folks have already been using a PCIe RC
      property "brcm,enable-l1ss".  These commits use the same
      property, in a backward-compatible manner, and the implementaion
      adds more detail and also automatically identifies devices w/o
      a clkreq# signal, i.e. most devices plugged into an RPi CM4
      IO board.
