Subject: [PATCH 2/4] dt-bindings: rtc: abx80x: Convert text bindings to YAML
Date: Tue, 5 Mar 2024 02:42:19 +0200 [thread overview]
Message-ID: <20240305004222.622-3-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20240305004222.622-1-laurent.pinchart@ideasonboard.com>
Convert the abx80x DT bindings to YAML schema. The existing properties
are kept without modification, and the interrupt property is added as it
is supported by the driver.

-Abracon ABX80X I2C ultra low power RTC/Alarm chip
-
-The Abracon ABX80X family consist of the ab0801, ab0803, ab0804, ab0805, ab1801,
-ab1803, ab1804 and ab1805. The ab0805 is the superset of ab080x and the ab1805
-is the superset of ab180x.
-
-Required properties:
-
- - "compatible": should one of:
- "abracon,abx80x"
- "abracon,ab0801"
- "abracon,ab0803"
- "abracon,ab0804"
- "abracon,ab0805"
- "abracon,ab1801"
- "abracon,ab1803"
- "abracon,ab1804"
- "abracon,ab1805"
- "microcrystal,rv1805"
- Using "abracon,abx80x" will enable chip autodetection.
- - "reg": I2C bus address of the device
-
-Optional properties:
-
-The abx804 and abx805 have a trickle charger that is able to charge the
-connected battery or supercap. Both the following properties have to be defined
-and valid to enable charging:
-
- - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
- - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
- resistor, the other values are in kOhm.
