Subject: [PATCH 07/11] dt-bindings: wkup_m3_ipc: Add scale-data-fw property
Date: Sat, 19 Feb 2022 13:53:24 -0800 [thread overview]
Message-ID: <20220219215328.485660-8-dfustini@baylibre.com> (raw)
In-Reply-To: <20220219215328.485660-1-dfustini@baylibre.com>
From: Dave Gerlach <d-gerlach@ti.com>
Add documentation for scale-data-fw property on the wkup_m3_ipc node to
enable I2C PMIC voltage scaling. The property contains the name of a
binary file for the CM3 firmware to load.
Based on previous work by Russ Dill.

+Support for I2C PMIC Voltage Scaling
+--------------------
+It is possible to pass the name of a binary file to laod to the CM3 firmware
+in order to provide I2C sequences for the CM3 to send out to the PMIC during
+low power mode entry.
+
+Optional properties:
+--------------------
+- scale-data-fw: Name of the firmware binary in /lib/firmware to copy to m3
+ aux data.

Support for VTT Toggle
==================================
In order to enable the support for VTT toggle during Suspend/Resume
