An example of a property I have defined in my bindings.yaml is this:
parity:
type: string
required: false
default: "NONE"
description: Sets the necessary UART parity required by the sensor.
enum:
- "NONE"
- "ODD"
- "EVEN"
- "MARK"
- "SPACE"
Now, using Zephyr's devicetree API, I can get these string literals back using DT_PROP(device, parity);. However, since Zephyr's UART API defines the following enums
UART_CFG_PARITY_NONE
UART_CFG_PARITY_ODD
UART_CFG_PARITY_EVEN
UART_CFG_PARITY_MARK
UART_CFG_PARITY_SPACE
I would like to convert the string literals to tokens such that I can reconstruct the enums and use them for compile time configuration. I.e. I would like to be able to write code like this:
static const struct uart_config config = {
.parity = SOME_MACRO(device, parity),
};
and have it expand to
static const struct uart_config config = {
.parity = UART_CFG_PARITY_<either of NONE, ODD, EVEN, MARK, SPACE>,
};
How can this be done?
