| # format of /etc/gpios file |
| # model gpio name active_low edge direction |
| # |
| # model: platform name. $platform and $platform-$hwver are checked. |
| # gpio: 0-63 or more |
| # name: name of gpio to put in /dev/gpio |
| # active_low: 0 or 1, inverts value and edge for read and write |
| # edge: none rising falling both |
| # direction: in out low high (low and high are out+value=0 and out+value=1) |
| # |
| # note we do not set value file, use high and low for that so it is atomic |
| # |
| # model, gpio and name are required, others are optional |
| # |
| # This file is parsed by update-gpio-links. |
| # File is parsed sequentially, and all platform matches are executed. |
| # |
| # Note: Default values (those not having an hwver part) apply to all hwver. |
| # If any GPIO defines an hwver part, all uses of that GPIO must define |
| # an hwver part (you can't use a default in that case). |
| # |
| # GFCH100 versions |
| # V1.0 proto (red) hnvram -w HW_VER=0 |
| # V1.0 evt (yellow) hnvram HW_VER is unset |
| # V1.2a + 85110 hnvram -w HW_VER=2 |
| # V1.2b + 85100 hnvram -w HW_VER=3 |
| # V1.2b + 85110 hnvram -w HW_VER=4 |
| # |
| # /etc/hw_ver is populated with the proper value on all board versions: |
| # GFCH100 versions /etc/hw_ver |
| # V1.0 proto (red) 0 |
| # V1.0 evt (yellow) 1 |
| # V1.2a + 85110 2 |
| # V1.2b + 85100 3 |
| # V1.2b + 85110 4 |
| # |
| # This file is using the values as returned by /etc/hw_ver |
| # |
| # Examples: |
| # |
| # configure but don't change value |
| # GFCH100 12 led_red 0 none out |
| # |
| # interrupt on 1->0 falling (rising inverted) |
| # GFCH100 31 reset_button 1 rising in |
| # |
| # set as output & low at same time (take out of reset) |
| # GFCH100 12 reset 1 none high |
| # |
| # just enable the gpio and create the link |
| # GFCH100 5 3220_reset |
| # |
| # model can have -[number] at end, to match a specific HW_VER value. |
| # to match an unset HW_VER, use model-, as in GFCH100- |
| # GFCH100-0 12 led_red 0 none out |
| # GFCH100-1 12 led_red 1 none out |
| # GFCH100 13 led_blue 0 none out |
