Merge tag 'mmc-updates-for-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc
Pull MMC updates from Chris Ball:
"MMC highlights for 3.14:
Core:
- Avoid get_cd() on cards marked nonremovable
Drivers:
- arasan: New driver for controllers found in e.g. Xilinx Zynq SoC
- dwmmc: Support Hisilicon K3 SoC controllers
- esdhc-imx: Support for HS200 mode, DDR modes on MX6, runtime PM
- sdhci-pci: Support O2Micro/BayHubTech controllers used in laptops
like Lenovo ThinkPad W540, Dell Latitude E5440, Dell Latitude E6540
- tegra: Support Tegra124 SoCs"
