linux-toradex.git/drivers/mfd/tc6393xb.c, branch v2.6.33.6 Linux kernel for Apalis and Colibri modules mfd: tmio_mmc hardware abstraction for CNF area 2010-01-18T11:30:27+00:00 Ian Molton ian@mnementh.co.uk 2010-01-06T12:51:48+00:00 64e8867ba8098b69889c1af94997a5ba2348fb26 This patch abstracts out the CNF area code from tmio_mmc which is not present in all hardware that can use this driver. This is required so that we can support non-toshiba based hardware.

With this patch, the MFD driver provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.
