Subject: [PATCH v1] ARM: dts: twl6032: Add DTS file for TWL6032 PMIC
Date: Tue, 11 Jun 2024 18:51:34 +0530
Message-Id: <20240611132134.31269-1-bavishimithil@gmail.com>
Precedence: bulk
MIME-Version: 1.0

From: Mithil Bavishi <bavishimithil@gmail.com>

Add a dedicated DTS file for the TWL6032 PMIC (Phoenix Lite). Already
has driver support with TWL6030 (Phoenix) since both of them are so
similar, some nodes can be reused from TWL6030 as well.

This can be included in the board files like twl6030.
Example:
...
&i2c1 {
    twl: twl@48 {
        reg = <0x48>;
        interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
        interrupt-controller;
        interrupt-parent = <&gic>;
    };
};

/include/ "twl6032.dtsi"
...

Used in devices like samsung-espresso, amazon-jem, epson-embt2ws etc.

Regulator values are found from downstream kernel for espresso.
