* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* mci: dw_mmc: Add support for high speed modesTrent Piepho2015-11-191-0/+2
| | | | | | | | | | | | | | | | The Synopsys DesignWare core supports 52 MHz MMC mode and 50 MHz SD mode, so add the cap flags so they are used. This works on socfpga. The other user of this driver is Rockchip and the datasheet I found for the RK30xx indicated it supported highspeed modes as well. The Linux kernel has DT properties, e.g. "cap-mmc-highspeed", but none of the drivers in barebox support this at all. They all specify flags in their code.

* mci: dw_mmc: Delete devname in platform_dataTrent Piepho2015-11-191-4/+1
| | | | | | | | | | | Nothing used it. Also delete the local mci alias pointer to host->mci in dw_mmc_probe(). It only saved a few characters and all the references but one are using host->mci. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: dw_mmc: socfpga: Supply bus-width in platform_dataTrent Piepho2015-11-191-11/+13
| | | | | | | | | | | | | | | | | Since there is no OF support in the xloader on socfpga it uses the platform_data system. There needs to be a way to supply the equivalent of the DT property bus-width this way to support devices that need to use a smaller bus. So that we don't need to put every flag that might get added to the MMC_CAP list into platform_data, just put the bus width ones into platform_data. The socfpga dts sources specify a bus-width of 4 so use that in the platform_data for socfpga.
