Subject: [PATCH v4 1/6] i3c: add addr and lvr to i2c_dev_desc structure
Date: Sun, 10 Mar 2019 13:58:38 +0000
Message-ID: <20190310135843.21154-2-pgaj@cadence.com> (raw)
In-Reply-To: <20190310135843.21154-1-pgaj@cadence.com>

I need to store address and lvr value for I2C devices without static definition
in DT. This allows secondary master to transmit DEFSLVS command properly.
