Subject: [PATCH 021/391] ARM: dts: sun8i-a83t-tbs-a711: Add powerup/down
support for the 3G modem
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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:
