Subject: [PATCH] spi: sun6i: Fix define for SUN6I_TFR_CTL_CS_MASK
Date: Thu, 13 Feb 2014 10:18:15 +0800	[thread overview]
Message-ID: <1392257895.3964.2.camel@phoenix> (raw)

Current code in sun6i_spi_set_cs() actually clears CPHA and CPOL bits which is
obvious wrong. The define for SUN6I_TFR_CTL_CS_MASK is wrong. Fix it.
