Configure Apalis MMC1 D6 GPIO on SDMMC3_CLK_LB_IN as reserved function without any pull-up/down. Configure GPIO_PV2 as SD1_CD# according to latest V1.1 HW. Leave SDMMC3_CLK_LB_OUT muxed as SDMMC3 with output driver enabled aka not tristated and input driver enabled as well as it features some magic properties even though the external loopback is disabled and the internal loopback used as per SDMMC_VENDOR_MISC_CNTRL_0 register's SDMMC_SPARE1 bits being set to 0xfffd according to the TRM! This pin is now a not-connect on V1.1 HW in order to avoid any interference. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
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.
