Subject: [PATCH 1/3] dspi: lx2160a: use IRQF_SHARED mode to request IRQ
Date:   Thu, 25 Oct 2018 16:29:37 +0800
Message-Id: <20181025082937.648-1-chuanhua.han@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some SoC share one irq number between DSPI controllers.
For example, on the LX2160 board, DSPI0 and DSPI1 share one irq number.
In this case, only one DSPI controller can register successfully,
and others will fail.
