Can we confirm that it doesn't break functionality on the following:
* d2net (MPP9_GPIO, /* Rear power switch (auto|off) */)
* db88f5281 (MPP9_GPIO, /* JP3, CON11.3 */)
* dns-323 (MPP9_GPIO, /* power button switch */)
* dns-323b (MPP9_GPIO, /* power button switch */)
* dns-323c (MPP9_GPIO, /* i/o left amber LED */)
* ls-chl (MPP9_GPIO, /* USB POWER */)
* ls_hgl (MPP9_GPIO, /* USB_PWR */)
* lsmini (MPP9_GPIO, /* LED_FUNC */)
* mv2120 (MPP9_GPIO, /* SATA 1 fail LED */)
* net2big (MPP9_GPIO, /* Rear power switch (auto|off) */)
* rd88f5181l-fxo (MPP9_GPIO, /* GE_RXERR */)
* rd88f5181l-ge (MPP9_GPIO, /* GE_RXERR */)
* terastation_pro2 (MPP9_GPIO, /* RTC int */)
* wnr854t (MPP9_GIGE, /* GE_RXERR */)
* wrt350n-v2 (MPP9_GIGE, /* GE_RXERR */)
Also, while I'm looking at it, Is it correct that four boards
(rd88f5181l-*, wnr854t, wrt350n-v2) use the same pin for the same
purpose, two declare it as GPIO, and two as GIGE... :-/ Perhaps part of
the same problem?
thx,
Jason.
