Like http://marc.info/?l=linux-usb&m=138200449428874&w=2 said: two more things are needed to be done: - If host_start fails, the host_stop should not be called, so we add check that ci->hcd is not NULL. - if the host_start fails at the beginning, we need to consider regulator mismatch issue.

According to Freescale imx28 Errata, "ENGR119653 USB: ARM to USB register error issue", All USB register write operations must use the ARM SWP instruction.

commit 3c1532df5c1b54b5f6246cdef94eeb73a39fe43a upstream.
In ftrace_syscall_enter(),
syscall_get_arguments(..., 0, n, ...)
if (i == 0) { <handle ORIG_r0> ...; n--;}
memcpy(..., n * sizeof(args[0]));
If 'number of arguments(n)' is zero and 'argument index(i)' is also zero in
syscall_get_arguments(), none of arguments should be copied by memcpy().
Otherwise 'n--' can be a big positive number and unexpected amount of data
will be copied. Tracing system calls which take no argument, say sync(void),
may hit this case and eventually make the system corrupted.
This patch fixes the issue both in syscall_get_arguments() and
syscall_set_arguments().

This API is used to set wakeup enable at PHY registers, in that case, the PHY can be waken up from suspend due to external events, like vbus change, dp/dm change and id change. Signed-off-by: Peter Chen <[email protected]>
When we need the PHY can be waken up by external signals, we can call this API. Besides, we call mxs_phy_disconnect_line at this API to close the connection between USB PHY and controller, after that, the line state from controller is SE0. Once the PHY is out of power, without calling mxs_phy_disconnect_line, there are unknown wakeups due to dp/dm floating at device mode. Signed-off-by: Peter Chen <[email protected]>
We need this to keep PHY's power on or off during the system suspend mode. If we need to enable USB wakeup, then we must keep PHY's power being on during the system suspend mode. Otherwise, we need to keep PHY's power being off to save power. Signed-off-by: Peter Chen <[email protected]>

When the controller is at suspend mode, it can be waken up by external events (like vbus, dp/dm or id change). Once we receive the wakeup interrupt, we need to resume the controller first, eg open clocks, disable some wakeup settings, etc. After that, the controller can receive the normal USB interrupts.

As DAPM would do the sync() for us, we don't need to handle it by ourselves. And leaving snd_soc_dapm_sync() here is dangerous because it would disable the clock from WM8962 during the short period of the output route changing since we don't leave the alternative route's enanbling to this machine driver but to DAPM core.

The downsizing ratio overflow check should cover every stripe in the split mode.

Existing pm_power_off function was in rtc-snvs. Given we need to reset the SAM3X and turn off the 5v supply on power down, lets implement a power-off driver to do this for now. TODO: Not the cleanest solution but it works, should revisit.
1. Enable RT5370 wifi driver 2. Enable udoo power down driver
