Subject: [PATCH v4 7/9] mfd: cgbc: Add virtual I2C bus support
Date: Fri, 02 Oct 2026 13:12:45 +0200 [thread overview]
Message-ID: <20261002-cgbc-i2c-storage-devices-support-v4-7-eb42e0f1df59@bootlin.com> (raw)
In-Reply-To: <20261002-cgbc-i2c-storage-devices-support-v4-0-eb42e0f1df59@bootlin.com>
Internally the Board Controller has a virtual I2C bus with some virtual
storage devices (EEPROM and RAM). So add a new I2C cell for this I2C
virtual bus.
