From a5eb8bbd66ccf9f169419f9652544aec771b7c57 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Tue, 11 Nov 2014 17:54:55 +0100 Subject: mmc: add Toshiba PCI SD controller driver This patch resurrects an old never-finished driver for Toshiba PCI SD controllers found in some older Toshiba laptops (such as Portege R100): 02:0d.0 System peripheral [0880]: Toshiba America Info Systems SD TypA Controller [1179:0805] (rev 05) The code is fixed, cleaned up and successfully tested with SD, SDHC, SDXC and MMC cards on Portege R100. (MMC cards don't even work in Windows!) SDIO probably does not work (don't have any SDIO card). The hardware is slow (around 2 MB/s - same in Windows) because it does not support bus mastering (busmaster enable bit cannot be set in PCI control reg). Also the card clock is limited to 16MHz (33MHz PCI clock divided by 2).
