From eb336b9003b1539bb4c4844e87751ff0b9ba1b60 Mon Sep 17 00:00:00 2001 From: Chuanhua Han Date: Mon, 29 Oct 2018 11:11:16 +0800 Subject: [PATCH] spi: spi-fsl-dspi: use IRQF_SHARED mode to request IRQ [ Upstream commit 13aed23927414137a017ac2f7d567001f714293f ] 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.
