Subject: [PATCH v2 2/7] spi/imx: use mx21 to name SPI_IMX_VER_0_0 function and macro
Date: Sun, 10 Jul 2011 01:16:36 +0800 [thread overview]
Message-ID: <1310231801-18761-3-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1310231801-18761-1-git-send-email-shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>
SPI_IMX_VER_0_0 covers i.mx21 and i.mx27. It makes more sense to
use mx21 rather than mx27 to name SPI_IMX_VER_0_0 function and
macro, since i.mx21 comes out ealier than i.mx27.
