Subject: [PATCH v3 07/13] spi: sunxi: rename constants to match between sun4i and sun6i
Date: 13 Jun 2016 17:46:51 -0000	[thread overview]
Message-ID: <c27d58f634daa4785e90c2716c8bb90399db3bf2.1465490774.git.hramrach@gmail.com> (raw)
In-Reply-To: <cover.1465490774.git.hramrach@gmail.com>

SUNXI_CTL_ -> SUNXI_TFR_CTL_
SUNXI_TFR_CTL_LMTF -> SUNXI_TFR_CTL_FBS
SUNXI_TFR_CTL_CS_ACTIVE_LOW -> SUNXI_TFR_CTL_SPOL
and some SUNXI_???_CTL_ -> SUNXI_CTL_
for constants migrated to different registers between sun4i and sun6i

No functional change.
