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. + +Cc: platform-driver-x86@vger.kernel.org +Cc: linux-x86_64@vger.kernel.org +Reviewed-by: Andreas Eberlein +Reviewed-by: Paul Spooren +Signed-off-by: Ed Wildgoose +Sighed-off-by: Philip Prindeville +--- + drivers/leds/leds-apu.c | 2 +- + drivers/platform/x86/Kconfig | 4 +- + drivers/platform/x86/pcengines-apuv2.c | 118 ++++++++++++++++++++++--- + 3 files changed, 107 insertions(+), 17 deletions(-) + +--- a/drivers/leds/leds-apu.c ++++ b/drivers/leds/leds-apu.c +@@ -183,7 +183,7 @@ static int __init apu_led_init(void) + + if (!(dmi_match(DMI_SYS_VENDOR, "PC Engines") && + (dmi_match(DMI_PRODUCT_NAME, "APU") || dmi_match(DMI_PRODUCT_NAME, "apu1")))) { +- pr_err("No PC Engines APUv1 board detected.
