+Subject: [PATCH v3 1/1] x86: Support APU5 in PCEngines platform driver
+To: platform-driver-x86 at vger.kernel.org, linux-x86_64 at vger.kernel.org
+Cc: Ed Wildgoose <lists at wildgooses.com>, Andres Salomon <dilinger at queued.net>, Andreas Eberlein <foodeas at aeberlein.de>, Paul Spooren <paul at 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.
