Subject: [PATCH 25/32] arm64: dts: mediatek: mt7988a-bpi-r4: Add MediaTek
|
|
MT6682A/RT5190A PMIC
|
|
|
|
Bananapi R4 Board contains a MT6682A pmic which is compatible to rt5190a.
|
|
Add its node to the i2 controller.
|
|
|
|
The BananaPi R4 board has a MediaTek MT6682A PMIC, a rebrand of the
|
|
Richtek RT5190A chip, connected to the I2C0 bus.
|
|
|
|
Add the relevant node and, while at it, also configure the regulators
|
|
from this PMIC that are used on this board.
|
|
|
|
Only Buck2/Buck3 voltage can be controlled by software.
|
|
|
|
BUCK4 input is 5V from BUCK1 output, and the resistor (mapped to RP30/RP31
|
|
on BPI-R4) configures BUCK4 output to 1.8V.
|
|
LDO input is 3.3V from 3.3VD, and the resistor (mapped to RP38/RP40 on
|
|
BPI-R4) configures LDO output to 1.8V.
