Hi all, This is the version 6 of hardware reset feature implementation. When eMMC card cannot response any command, signal RST_n can help to reset eMMC card.
patch1: enable HW reset capability if card supports. patch2: do hardware reset if card occurs read/write/erase timeout patch3: implement hwreset_emmc and reinit_emmc callbacks. In this patch, hwreset_emmc callback will pull up/down the corresponded GPIO line number to trigger RST_n signal. change log: 1. Move hardware_reset callback to mmc_bus_ops so that all kinds of host controller can use hardware_reset callback to trigger RST_n signal. Different host controller only needs to provide a GPIO line number to this callback. 2. Add GPIO pull up/down part in hardware_reset callback. 3. Remove reset_emmc callback in sdhci_ops.
