Subject: [PATCH 020/469] ARM: dts: sun8i-a83t-tbs-a711: Add powerup/down
|
||
|
|
support for the 3G modem

The modem needs tree gpios to be powered-up:
|
||
|
|
- PL10 = reset
|
||
|
|
- PL8 = On/Off
|
||
|
|
- PL9 = vbat
|
||
|
|
Because of that, the PL9 corresponds to the regulator's gpio whereas
|
||
|
|
the PL8 (on/off) will be a power-gpio of the power sequence.
|
||
|
|
|
||
|
|
Thanks to that, the modem is powered up:
