Currently the following eMMC error is seen: mmc1: mmc_select_hs200 failed, error -74 mmc1: new MMC card at address 0001 mmcblk1: mmc1:0001 V10008 7.05 GiB mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB mmcblk1boot1: mmc1:0001 V10008 partition 2 4.00 MiB mmcblk1rpmb: mmc1:0001 V10008 partition 3 4.00 MiB On imx7s-warp the eMMC VCCQ is fixed at 3.15V, so pass the 'no-1-8-v' property to properly describe that 1.8V operation is not possible. With this change HS200 error is gone and another benefit is that the card can operate in DDR52 mode now: mmc1: new DDR MMC card at address 0001 mmcblk1: mmc1:0001 V10008 7.05 GiB mmcblk1boot0: mmc1:0001 V10008 partition 1 4.00 MiB mmcblk1boot1: mmc1:0001 V10008 partition 2 4.00 MiB mmcblk1rpmb: mmc1:0001 V10008 partition 3 4.00 MiB Suggested-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org> |

README
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.
