Subject: [PATCH 07/22] ARM: omap1: move perseus spi pinconf to board file
Date: Thu,  8 Aug 2019 23:22:16 +0200	[thread overview]
Message-ID: <20190808212234.2213262-8-arnd@arndb.de> (raw)
In-Reply-To: <20190808212234.2213262-1-arnd@arndb.de>

The driver has always had a FIXME about this, and it seems
like this trivial code move avoids a mach header inclusion,
so just do it.

With that out of the way, and the header file inclusions
changed to global files, the driver can also be compile-tested
on other platforms.
