* mmc: toshsd: use module_pci_driver to simplify the codeWei Yongjun2015-01-19
| | | | | | | | Use the module_pci_driver() macro to make the code simpler by eliminating module_init and module_exit calls. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
* mmc: toshsd: move dereference below check for NULLDan Carpenter2014-11-26
| | | | | | | | | | | | We check for NULL pointers after dereferencing so it's too late. Oddly enough, Smatch misses this code but complains about the caller passing NULL pointers to this function: drivers/mmc/host/toshsd.c:389 toshsd_irq() error: we previously assumed 'host->cmd' could be null (see line 349) Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
* mmc: add Toshiba PCI SD controller driverOndrej Zary2014-11-26
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). Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
