Date: Thu, 4 Jun 2009 20:12:36 +0200 From: Philipp Zabel <philipp.zabel@...il.com> To: linux-kernel@...r.kernel.org Cc: Ian Molton <ian@...menth.co.uk>, Pierre Ossman <pierre@...man.eu>, Philipp Zabel <philipp.zabel@...il.com> Subject: [PATCH 6/7] mmc: tmio_mmc: fix SDCLK divider setting Except for the SDCLK = HCLK (divider bypassed) case, the clock setting resulted in double the requested frequency. The smallest possible frequency (f_max/512) is configured with a divider setting 0x80, not 0x40.
