Subject: [PATCH v2 2/5] scsi: ufs: Rename tc-dwc-g210 -> tc-dwc
Date:   Fri, 24 Apr 2020 15:44:46 +0200
Message-Id: <d14c561930fc7345d2c847e3b3b87e00b6a2a25c.1587735561.git.Jose.Abreu@synopsys.com>

In-Reply-To: <cover.1587735561.git.Jose.Abreu@synopsys.com>
References: <cover.1587735561.git.Jose.Abreu@synopsys.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In preparation for the addition of new Synopsys Test Chips versions we
remove all G210 mentions in files and Kconfig entries so that we can
re-use the same driver for different Test Chips.

As the PCI ID for these chips is different and as we will have different
DT bindings, there is no reason to add new drivers for them and we can
just re-use the existing ones.

No functional change.
