Subject: [PATCH v2 2/5] x86/io: Include asm-generic/io.h to architectural code
Date: Fri, 30 Jun 2017 20:09:31 +0300 [thread overview]
Message-ID: <20170630170934.83028-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170630170934.83028-1-andriy.shevchenko@linux.intel.com>
asm-generic/io.h defines few helpers which would be useful in the drivers,
such as writesb() and readsb().
Include it to the asm/io.h in architectural folder.
Acked-by: Wolfram Sang <wsa@the-dreams.de>
