X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a477f6b8c1849701981f6e00e7afcd35af75546;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git davinci: dm365: disable pulldowns for all MMC/SD1 pins. This patch disables internal pulldowns for all MMC/SD1 pins. Presently only MMCSD1_CMD pin's pull down is disabled, but with this some MMC/SD cards do not get detected on MMC/SD1 slot of the EVM. The problem was reproducible with SanDisk 4GB SDHC card.
