From f0e46cc4971f6be96010d9248e0fc076b229d989 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 4 Jun 2009 20:12:31 +0200 Subject: MFD,mmc: tmio_mmc: make HCLK configurable The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK and AMD Imageon w228x's HCLK is 80 MHz. With this patch, the MFD driver provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.

The hclk mmc_data field can be const though.
