From: Markus Pietrek Date: Tue, 2 Feb 2010 02:29:15 +0000 (+0900) Subject: spi: spi_sh_msiof: Fixed data sampling on the correct edge X-Git-Tag: v2.6.33-rc7~42^2~3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e8708ef7e86a463b3a5b01d4a9abf16c8748b464;p=pandora-kernel.git spi: spi_sh_msiof: Fixed data sampling on the correct edge The spi_sh_msiof.c driver presently misconfigures REDG and TEDG. TEDG==0 outputs data at the **rising edge** of the clock and REDG==0 samples data at the **falling edge** of the clock. Therefore for SPI, TEDG must be equal to REDG, otherwise the last byte received is not sampled in SPI mode 3. This brings the driver in line with the SH7723 HW Reference Manual settings documented in Figures 20.20 and 20.21 ("SPI Clock and data timing").
