Message-Id: <20221005212631.122145-1-robh@kernel.org>
Date: Wed, 5 Oct 2022 16:26:31 -0500
From: Rob Herring <robh@...nel.org>

Serge Semin <fancer.lancer@...il.com>
Cc: devicetree@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH] dt-bindings: misc: Convert IDT 89HPESx to DT schema
Convert the IDT 89HPESx device binding to DT schema format.
"onsemi,24c64" was not a documented compatible string, so update the
example to "atmel,24c64". It's not clear what's in use here as no
upstream dts files have the eeprom child node.

Serge, Okay with dual licensing?

-EEPROM / CSR SMBus-slave interface of IDT 89HPESx devices
-
-Required properties:
- - compatible : should be "<manufacturer>,<type>"
- Basically there is only one manufacturer: idt, but some
- compatible devices may be produced in future. Following devices
- are supported: 89hpes8nt2, 89hpes12nt3, 89hpes24nt6ag2,
- 89hpes32nt8ag2, 89hpes32nt8bg2, 89hpes12nt12g2, 89hpes16nt16g2,
- 89hpes24nt24g2, 89hpes32nt24ag2, 89hpes32nt24bg2;
- 89hpes12n3, 89hpes12n3a, 89hpes24n3, 89hpes24n3a;
- 89hpes32h8, 89hpes32h8g2, 89hpes48h12, 89hpes48h12g2,
- 89hpes48h12ag2, 89hpes16h16, 89hpes22h16, 89hpes22h16g2,
- 89hpes34h16, 89hpes34h16g2, 89hpes64h16, 89hpes64h16g2,
- 89hpes64h16ag2;
- 89hpes12t3g2, 89hpes24t3g2, 89hpes16t4, 89hpes4t4g2,
- 89hpes10t4g2, 89hpes16t4g2, 89hpes16t4ag2, 89hpes5t5,
- 89hpes6t5, 89hpes8t5, 89hpes8t5a, 89hpes24t6, 89hpes6t6g2,
- 89hpes24t6g2, 89hpes16t7, 89hpes32t8, 89hpes32t8g2,
- 89hpes48t12, 89hpes48t12g2.
- - reg : I2C address of the IDT 89HPESx device.
-
-Optionally there can be EEPROM-compatible subnode:
- - compatible: There are five EEPROM devices supported: 24c32, 24c64, 24c128,
- 24c256 and 24c512 differed by size.
- - reg: Custom address of EEPROM device (If not specified IDT 89HPESx
- (optional) device will try to communicate with EEPROM sited by default
- address - 0x50)
- - read-only : Parameterless property disables writes to the EEPROM
- (optional)
-
-Example:
- idt@60 {
- compatible = "idt,89hpes32nt8ag2";
- reg = <0x74>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- eeprom@50 {
- compatible = "onsemi,24c64";
- reg = <0x50>;
- read-only;
- };
- };
