Add card_busy host ops in sdhci_omap to check card busy status. The voltage switching sequence for AM572x platform is mentioned in Figure 25-48. eMMC/SD/SDIO Power Switching Procedure of AM572x Sitara Processors Silicon Revision 2.0, 1.1 TRM (SPRUHZ6I - October 2014–Revised April 2017 [1]). In the voltage switching sequence, CLKEXTFREE bit in MMCHS_CON should also be set after switching to 1.8v which is also taken care in the card_busy ops.

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.
