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.
