Kishon Vijay Abraham I 8cc9a3e73d mmc: host: omap_hsmmc: use generic_cmd6_time to program timeout value for CMD6 ... commit e2bf08d643 ("omap_hsmmc: set a large data timeout for commands with busy signal") sets an arbitrary timeout value (100ms) for commands like CMD6 (MMC SWITCH). However extended CSD register defined in the eMMC standard has a field for GENERIC_CMD6_TIME which indicates the default maximum timeout for a SWITCH command. Use busy_timeout of cmd structure (populated with GENERIC_CMD6_TIME in the case of SWITCH command) to program the data timeout value in omap_hsmmc driver. SWITCH command to turn the cache on took more than 100ms to complete with MICRON eMMC card present in AM572x IDK REV 1.3A resulting in timeout and failed enumeration. It is fixed here by programming the timeout with the value advertised in GENERIC_CMD6_TIME.
