From 74be81daeb5e6aaaa309b123eb4db71658f9fa06 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ond=C5=99ej=20Jirman?= Date: Sat, 9 Nov 2019 23:55:48 +0100 Subject: [PATCH 111/484] 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).
