These 3 commits from upstream allow us to have more fine grained control
over the MMC command timeouts and this solves the following timeouts
that we have seen on our systems across suspend/resume cycles:

[   14.907496] usb usb2: root hub lost power or was reset
[   15.216232] usb 1-1: reset high-speed USB device number 2 using
xhci-hcd
[   15.485812] bcmgenet 8f00000.ethernet eth0: Link is Down
[   15.525328] mmc1: error -110 doing runtime resume
[   15.531864] OOM killer enabled.

Thanks!

Ulf Hansson (3):
  mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMC
  mmc: block: Use generic_cmd6_time when modifying
    INAND_CMD38_ARG_EXT_CSD
  mmc: core: Default to generic_cmd6_time as timeout in __mmc_switch()
