On Intel Edison the Broadcom Wi-Fi card, which is connected to SDIO, requires 2.0v, while the host, according to Intel Merrifield TRM, supports 1.8v supply only. The card announces itself as mmc2: new ultra high speed DDR50 SDIO card at address 0001 Introduce a custom OCR mask for SDIO host controller on Intel Merrifield and add a special case to sdhci_set_power_noreg() to override 2.0v supply by enforcing 1.8v power choice.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
