[PATCH v4] media: dt-bindings: Convert Analog Devices ad5820 to DT schema
Posted by David Heidelberg via B4 Relay 8 months ago
From: David Heidelberg <david@ixit.cz>

Convert the Analog Devices ad5820 to DT schema format.

Acked-by: Pavel Machek <pavel@ucw.cz>
Signed-off-by: David Heidelberg <david@ixit.cz>
---
Changes in v4:
- Drop remaining pieces of iio-channel-cells introduced in previous
  revisions.
- Link to v3: https://lore.kernel.org/r/20250414-b4-ad5820-dt-yaml-v3-1-39bbb5db7b2b@ixit.cz

Changes in v3:
- Removed documentation of io-channel-cells property. Now it's 1:1 to
  the original binding. The reference to it from the Nokia N900 dts
  was removed in the -next.
- Link to v2: https://lore.kernel.org/r/20250314-b4-ad5820-dt-yaml-v2-1-287958c3c07c@ixit.cz

Changes in v2:
- added MAINTAINERS entry for the binding
- documented why io-channel-cells got added into the binding.
- dropped io-channel-cells in required properties.
- adjusted example indentation to 4 spaces.
- Link to v1: https://lore.kernel.org/r/20250209203940.159088-1-david@ixit.cz

-* Analog Devices AD5820 autofocus coil
-
-Required Properties:
-
-  - compatible: Must contain one of:
-		- "adi,ad5820"
-		- "adi,ad5821"
-		- "adi,ad5823"
-
-  - reg: I2C slave address
-
-  - VANA-supply: supply of voltage for VANA pin
-
-Optional properties:
-
-   - enable-gpios : GPIO spec for the XSHUTDOWN pin. The XSHUTDOWN signal is
-active low, a high level on the pin enables the device.
-
-Example:
-
-       ad5820: coil@c {
-               compatible = "adi,ad5820";
-               reg = <0x0c>;
-
-               VANA-supply = <&vaux4>;
-               enable-gpios = <&msmgpio 26 GPIO_ACTIVE_HIGH>;
-       };
