There could be race condition between h/w initiating sof
(start of frames) and finishing port reset. This can
cause hsic phy lockup, which results in enumeration failure.
Avoid this race condition by:
1. Moving to the old enumeration sequence where set_address is
initiated before get_device descriptor. This results in one
port reset instead of two port resets.
2. Halt usb controller before initiating port reset and start it after
port reset is complete. This is tricky because PORT_RESET bit
automatically clears when h/w completes the reset and failure to
start the controller within 3ms causes the peripheral device to
suspend resulting in enumeration failure. Hence, after setting
port reset bit forcefully drive strobe/data lines to reset using
ulpi interface and once port reset is complete, disable forceful
reset and start the controller in atomic context.

This bug was introduced in the 'MMC-4.5 Power OFF Notify Rework' fix.
Prior to the aforementioned patch, during resume mmc_init_card was being
invoked. The aforesaid patch invokes mmc_card_awake, prior to which
mmc_power_up has already set the clock frequency to 400Khz. Since the card
init is not done again, this frequency stays as is and results in data
time-out errors.
Two new functions
* mmc_save_ios
* mmc_restore_ios
were added.
The mmc_save_ios is invoked during mmc_suspend process and it saves the
current ios values, while mmc_restore_ios is invoked during mmc_resume process
and restores the previous ios values before sending the awake command. This
ensures that the clock, timing, bus-width etc are set properly before any
request is sent to the driver.

This is a rework of the existing POWER OFF NOTIFY patch. The current problem
with the patch comes from the ambiguity on the usage of POWER OFF NOTIFY
together with SLEEP and misunderstanding on the usage of MMC_POWER_OFF
power_mode from mmc_set_ios in different host controller drivers.
This new patch works around this problem by adding a new host CAP,
MMC_CAP2_POWER_OFF_VCCQ_DURING_SUSPEND, which when set sends a
POWER OFF NOTIFY from mmc_suspend instead of SLEEP. It is expected that host
controller drivers will set this CAP, if they switch off both Vcc and Vccq
from MMC_POWER_OFF condition within mmc_set_ios. However, note that there
is no harm in sending MMC_POWER_NOTIFY even if Vccq is not switched off.
This patch also sends POWER OFF NOTIFY from power management routines (e.g.
mmc_power_save_host, mmc_pm_notify/PM_SUSPEND_PREPARE, mmc_stop_host), which
does reinitialization of the eMMC on the return path of the power management
routines (e.g. mmc_power_restore_host, mmc_pm_notify/PM_POST_RESTORE,
mmc_start_host).
This patch sets POWER_OFF_NOTIFICATION to POWER_OFF_SHORT if it is sent from
the suspend sequence. If it is sent from shutdown sequence then it is set to
POWER_OFF_LONG.
Earlier implementation of PowerOff Notify as a core function is replaced as
a device's bus operation.

the packing can be configured via sysfs by writing the required value to:

Enable eMMC background operations (BKOPS) feature.
If URGENT_BKOPS is set after a response, note that BKOPS
are required. After all I/O requests are finished, run
BKOPS if required. Should read/write operations be requested
during BKOPS, first issue HPI to interrupt the ongoing BKOPS
and then service the request.
If BKOPS-STATUS is upper than LEVEL2, need to check until clear
the BKOPS-STATUS vaule.
If you want to enable this feature, set MMC_CAP2_BKOPS.
And if you want to set the BKOPS_EN bit in ext_csd register,
use the MMC_CAP2_INIT_BKOPS.
Future considerations
* Check BKOPS_LEVEL=1 and start BKOPS in a preventive manner.
* Interrupt ongoing BKOPS before powering off the card.
* How get BKOPS_STATUS value.(periodically send ext_csd command?)
