From 970d9af9015a387bb81841faf05dcc1a171eb97a Mon Sep 17 00:00:00 2001
From: Philip Prindeville <philipp@redfish-solutions.com>
Date: Sun, 1 Jan 2023 15:25:04 -0700
Subject: [PATCH v3 1/1] x86: Support APU5 in PCEngines platform driver
To: platform-driver-x86@vger.kernel.org, linux-x86_64@vger.kernel.org
Cc: Ed Wildgoose <lists@wildgooses.com>, Andres Salomon <dilinger@queued.net>, Andreas Eberlein <foodeas@aeberlein.de>, Paul Spooren <paul@spooren.de>
PCEngines make a number of SBC. APU5 has 5 mpcie slots + MSATA.
It also has support for 3x LTE modems with 6x SIM slots (pairs with a
SIM switch device). Each mpcie slot for modems has a reset GPIO
To ensure that the naming is sane between APU2-6 the GPIOS are
renamed to be modem1-reset, modem2-reset, etc. This is significant
because the slots that can be reset change between APU2 and APU3/4
GPIO for simswap is moved to the end of the list as it could be dropped
for APU2 boards (but causes no harm to leave it in, hardware could be
added to a future rev of the board).
Structure of the GPIOs for APU5 is extremely similar to APU2-4, but
many lines are moved around and there are simply more
modems/resets/sim-swap lines to breakout.
Also added APU6, which is essentially APU4 with a different ethernet
interface and SFP cage on eth0.
Revision history:
v1: originally titled, "apu6: add apu6 variation to apu2 driver family"
this dealt only with detecting the APUv6, which is otherwise identical
to the v4 excepting the SFP cage on eth0.
v2: at Ed's request, merged with his previous pull-request titled
"x86: Support APU5 in PCEngines platform driver", and some cleanup
to that changeset (including dropping the table "apu5_driver_data"
which did not have a defined type "struct apu_driver_data"), but got
mistitled when the Subject of that commit got accidentally dropped.
v3: retitled to match Ed's previous pull-request.
