Subject: [RFT v2 04/10] pinctrl: samsung: Add dedicated compatible for S5Pv210 wakeup interrupts
Date:   Mon, 23 Jul 2018 19:52:56 +0200
Message-Id: <20180723175302.22535-5-krzk@kernel.org>
In-Reply-To: <20180723175302.22535-1-krzk@kernel.org>
References: <20180723175302.22535-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The S5Pv210 external wakeup interrupts differ from Exynos therefore
separate compatible is needed.  Duplicate existing flavor specific data
from exynos4210_wkup_irq_chip and add new compatible for S5Pv210.
At this point this new compatible does not bring anything new and works
exactly as existing "samsung,exynos4210-wakeup-eint".
