Subject: [PATCH 3/6] serial: ifx6x60: changed internal bpw from boolean to int
Date: Mon, 7 Feb 2011 12:02:29 -0800 [thread overview]
Message-ID: <1297108952-27371-4-git-send-email-russ.gorby@intel.com> (raw)
In-Reply-To: <[PATCH 0/6] IFX6X60 patchset : 02/07/2011>
driver should support 32bit SPI transfers. The boolean variable
only allowed 8/16.
Changed to support 8/16/32 for future enabling
of 32 bpw.
