V3 Changes:
o Commit "Enable 7712 SOCs"
-- Move "model" check from outside to inside func (Stan)
o Commit "Check return value of all reset_control_xxx calls"
-- Propagate errors up the chain instead of ignoring them (Stan)
o Commit "Refactor for chips with many regular inbound BARs"
-- Nine suggestions given, nine implemented (Stan)
o Commit "Make HARD_DEBUG, INTR2_CPU_BASE offsets SoC-specific"
-- Drop tab, add parens around macro params in expression (Stan)
o Commit "Use swinit reset if available"
-- Treat swinit the same as other reset controllers (Stan)
Stan suggested to use dev_err_probe() for getting resources
but I will defer that to future series (if that's okay).
o Commit "Get resource before we start asserting resets"
-- Squash this with previous commit (Stan)
o Commit "Use "clk_out" error path label"
-- Move clk_prepare_enable() after getting resouurces (Stan)
-- Change subject to "Use more common error handling code in
brcm_pcie_probe()" (Markus)
-- Use imperative commit description (Markus)
-- "Fixes:" tag added for missing error return. (Markus)
o Commit "dt-bindings: PCI ..."
-- Split off maintainer change in separate commit.
-- Tried to accomodate Krzysztof's requests, I'm not sure I
have succeeded. Krzysztof, please see [1] below.
[1] Wrt the YAML of brcmstb PCIe resets, here is what I am trying
to describe:
CHIP NUM_RESETS NAMES
==== ========== =====
4908 1 perst
7216 1 rescal
7712 3 rescal, bridge, swinit
Others 0 -
V2 Changes (note: four new commits):
o Commit "dt-bindings: PCI ..."
-- s/Adds/Add/, fix spelling error (Bjorn)
-- Order compatible strings alphabetically (Krzysztof)
-- Give definitions first then rules (Krzysztof)
-- Add reason for change in maintainer (Krzysztof)
o Commit "Use swinit reset if available"
-- no need for "else" clause (Philipp)
-- fix improper use of dev_err_probe() (Philipp)
o Commit "Use "clk_out" error path label"
-- Improve commit message (Bjorn)
o Commit "PCI: brcmstb: Make HARD_DEBUG, INTR2_CPU_BASE offsets SoC-specific"
-- Improve commit subject line (Bjorn)
o Commit (NEW) -- Change field name from 'type' to 'model'
-- Added as requested (Stanimir)
o Commit (NEW) -- Check return value of all reset_control_xxx calls
-- Added as requested (Stanimir)
o Commit (NEW) "Get resource before we start asserting reset controllers"
-- Added as requested (Stanimir)
o Commit (NEW) -- "Remove two unused constants from driver"
V1:
This submission is for the Broadcom STB 7712, sibling SOC of the RPi5 chip.
Stanimir has already submitted a patch "Add PCIe support for bcm2712" for
the RPi version of the SOC. It is hoped that Stanimir will allow us to
submit this series first and subsequently rebase his patch(es).
The largest commit, "Refactor for chips with many regular inbound BARs"
affects both the STB and RPi SOCs. It allows for multiple inbound ranges
where previously only one was effectively used. This feature will also
be present in future STB chips, as well as Broadcom's Cable Modem group.
