Subject: [PATCH v2 0/3] PCI: brcmstb: CLKREQ# accomodations of downstream device
Date: Tue, 11 Apr 2023 12:59:15 -0400 [thread overview]
Message-ID: <20230411165919.23955-1-jim2101024@gmail.com> (raw)
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.
