Subject: [PATCH 2/4] i3c: master: cdns: Drop support for I2C 10 bit addresing in Cadence I3C master
Date: Thu, 7 Mar 2019 09:58:06 +0000	[thread overview]
Message-ID: <20190307095808.22540-3-pgaj@cadence.com> (raw)
In-Reply-To: <20190307095808.22540-1-pgaj@cadence.com>

Because this patch series dropped support for 10 bit I2C devices, support is
also dropped in Cadence I3C master driver.
