Subject: [PATCH 4/4] dt-bindings: sc16is7xx: convert to YAML
Date: Wed, 20 Sep 2023 11:20:15 -0400 [thread overview]
Message-ID: <20230920152015.1376838-5-hugo@hugovil.com> (raw)
In-Reply-To: <20230920152015.1376838-1-hugo@hugovil.com>
From: Hugo Villeneuve <hvilleneuve@dimonoff.com>
Convert binding from text format to YAML.
Additions to original text binding:
- add rs485 reference.

-* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
-* i2c as bus
-
-Required properties:
-- compatible: Should be one of the following:
- - "nxp,sc16is740" for NXP SC16IS740,
- - "nxp,sc16is741" for NXP SC16IS741,
- - "nxp,sc16is750" for NXP SC16IS750,
- - "nxp,sc16is752" for NXP SC16IS752,
- - "nxp,sc16is760" for NXP SC16IS760,
- - "nxp,sc16is762" for NXP SC16IS762.
-- reg: I2C address of the SC16IS7xx device.
-- interrupts: Should contain the UART interrupt
-- clocks: Reference to the IC source clock.
- OR (when there is no clock provider visible to the platform)
-- clock-frequency: The source clock frequency for the IC.
-
-Optional properties:
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be two. The first cell is the GPIO number and
- the second cell is used to specify the GPIO polarity:
- 0 = active high,
- 1 = active low.
-- nxp,irda-mode-ports: An array that lists the indices of the port that
- should operate in IrDA mode.
-- nxp,modem-control-line-ports: An array that lists the indices of the port that
- should have shared GPIO lines configured as
- modem control lines.
-
-Example:
- sc16is750: sc16is750@51 {
- compatible = "nxp,sc16is750";
- reg = <0x51>;
- clocks = <&clk20m>;

- - "nxp,sc16is762" for NXP SC16IS762.
-- reg: SPI chip select number.
-- interrupts: Specifies the interrupt source of the parent interrupt
- controller. The format of the interrupt specifier depends on the
- parent interrupt controller.
-- clocks: phandle to the IC source clock.
-
-Optional properties:
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be two. The first cell is the GPIO number and
- the second cell is used to specify the GPIO polarity:
