Subject: [PATCH v2 08/10] ARM: OMAP1: Get rid of <mach/ams-delta-fiq.h>
Date:   Fri, 22 Jun 2018 00:41:26 +0200
Message-Id: <20180621224128.17623-8-jmkrzyszt@gmail.com>
In-Reply-To: <20180621224128.17623-1-jmkrzyszt@gmail.com>
References: <20180609140224.32606-1-jmkrzyszt@gmail.com>
 <20180621224128.17623-1-jmkrzyszt@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Split the header file into two parts and move them to directories where
they belong.

Information on internal structure of FIQ buffer is moved to
<linux/platform_data/ams-delta-fiq.h> for ams-delta-serio driver use.

Other information used by ams-delta board init file and FIQ code is
made local to mach-omap1 root directory.

Changelog:
v2: rebased on v4.18-rc1, no conflicts
