The patch titled spi_mpc83xx: fix clockrate calculation for low speed has been removed from the -mm tree. Its filename was spi_mpc83xx-fix-clockrate-calculation-for-low-speed.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: spi_mpc83xx: fix clockrate calculation for low speed From: Peter Korsgaard <jacmet@xxxxxxxxxx> Commit a61f5345 (spi_mpc83xx clockrate fixes) broke clockrate calculation for low speeds. SPMODE_DIV16 should be set if the divider is higher than 64, not only if the divider gets clipped to 1024. Furthermore, the clipping check was off by a factor 16 as well.
