Mike I already sent a patch some time ago, it addresses this bug and alot more. See spi-devel-general <[EMAIL PROTECTED]>, I am waiting for David B. to comment/apply it. If you want to see this in 2.6.25 I suggest you remind 'David Brownell' <[EMAIL PROTECTED]> Jocke On Mon, 2008-03-31 at 08:04

[PATCH] mpc83xx SPI glitch

2008-03-31 Thread Mike Hench
dont write SPMODE reg unless mode changed. it causes SPI to go hi-z momentarily which can cause a spike on the CLK line this is a problem in MMC where /CS is held asserted across multiple transactions. Signed-off-by: Mike Hench <[EMAIL PROTECTED]> --- --- linux-2.6.25-rc5.orig/drivers/spi/spi_mp
