Subject: [PATCH] powerpc: dts: Fix the bug that intx interrupt not work in P1010RDB-PB
Date:   Mon, 20 May 2019 13:53:08 +0800
Message-Id: <20190520055308.43907-1-xiaowei.bao@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Due to the INTA is shared with the active-low PHY2 interrupt on P1010RDB-PA
board, so configure P1010RDB-PA's INTA with polarity as active-low, the
P1010RDB-PB board is used separately, so configure P1010RDB-PB's INTA with
polarity as active-high.
The INTX in P1010RDB-PB do not work because of the pcie@0 node fixup will be
overwrited by p1010si-post.dtsi file, so we move the pcie@0 node fixup to
p1010rdb-pb.dts and p1010rdb-pb_36b.dts.
