Subject: [PATCH 016/351] ARM: dts: sun8i-a83t-tbs-a711: Add support for the
|
||
|
|
vibrator motor
|
||
|
|
|
||
|
|
The board has a vibrator mottor. Hook it to the input subsystem.
|
||
|
|
|
||
|
|
According to the PMIC specification, LDO needs to be enabled (value 0b11)
|
||
|
|
to achieve the specified max driving current of 150mA. We can't drive
|
||
|
|
the motor with just GPIO mode.
|
||
|
|
|
||
|
|
In GPIO mode the chip is probably just using the regular CMOS logic
|
||
|
|
output circuitry (typically limited to around 20-35mA, but not specified
|
||
|
|
in this datasheet).
