description: Booster soft start values
orientation-flipped:
type: boolean
description: Last column address is mapped to first segment
reset-gpios:
type: phandle-array
required: true
description: RESET pin.
The RESET pin of SSD16XX is active low.
If connected directly the MCU pin should be configured
as active low.
dc-gpios:
type: phandle-array
required: true
description: DC pin.
The DC pin of SSD16XX is active low (transmission command byte).
If connected directly the MCU pin should be configured
as active low.
busy-gpios:
type: phandle-array
required: true
description: BUSY pin.
The BUSY pin of SSD16XX is active high.
If connected directly the MCU pin should be configured
as active high.
tssv:
type: int
description: Temperature Sensor Selection Value
Display controller can have integrated temperature sensor or
an external temperature sensor is connected to the controller.
The value selects which sensor should be used.

Child nodes describe refresh profiles. Each refresh profile
specifies a set of voltages used to drive the refresh
cycle. Refresh profiles are optional and are used to override
defaults loaded from the controllers OTP memory.
Partial refresh will be disabled unless a partial refresh profile
has been specified. That profile may be empty to use the defaults
loaded from OTP if supported by the device.
The driver typically looks for the following child nodes:
- 'full' - Normal / full refresh.
- 'partial' - Partial refresh.
