EHCI: HSIC: Prevent disabling wakeup irq twice

If PM resume and Wakeup irq happen at same time
its possible to disable wakeup irq twice. Prevent
the same by protecting with spinlock

msm: hsic: Disallow processor idle sleep while driving resume signal

HSIC controller should send SOF with in 3 msec after completing
the resume signal.  If processor is in idle sleep state, the timer
interrupt generated by HSIC controller to indicate resume completion
gets delayed.  If the interrupt handler is not run with in 3msec
after resume, the resume sequence is repeated.  Disallow processor
idle sleep to avoid multiple resume cycles.

EHCI: HSIC: Fail root hub bus suspend when port is not enabled.

HSIC controller can not detect HSIC device in low power mode.  Hence
controller suspend is allowed only when port is enabled.  But this
check is done in controller suspend routine.  Controller suspend is
attempted after root hub bus is suspended.  Even if we fail, controller
suspend, root hub bus remains in suspend state.  This would delay
the enumeration of HSIC device as root hub bus resume takes some time.

USB: Allow skipping device resume during system resume

Some buses would like to keep their devices in suspend state during system
resume.  For example HSIC controller driver prevent system suspend when
HSIC device is active.  If this device is resumed, during system resume
HSIC controller acquire wake lock and prevent the subsequent suspend till
HSIC device is auto suspended.

EHCI: HSIC: Handle wakeup interrupt properly during probe

During HSIC probe driver registers the level triggered interrupt
on wakeup gpio. Wakeup irq line is disabled based on the return
status of interrupt registration. There is a possibility that
wakeup gpio is already pulled high after registering the interrupt
which can cause wakeup interrupts to be fired on continuously
without getting chance to disable the irq line. Hence do not
enable wake up interrupt on request irq.

EHCI: HSIC: Add enhancements to debug logging

This change addresses following enhancements to debug
logging:-

1) Add data payload logging which is not currently
supported. This helps to sniff first 32 bytes of data
being sent and received. Data payload logging is
enabled by default. To disable data payload logging:-

echo 0 > /sys/module/ehci_hcd/parameters/enable_payload_log

2) Current urb submission event logging does not cover
root hub submissions, hence move urb submission logging
to hcd driver.

3) Current urb submission event logging does not return
the correct status if submission fails. Hence log the
return status of urb submission.

usb: ehci-msm-hsic: Fix compilation error

The ehci-msm-hsic driver's bus suspend and resume functions
depend on ehci_hcd's bus_suspend/resume functions, which are
NULL when CONFIG_PM is not defined. Fix the compilation error
by also #defining these sub-driver functions NULL, as they
are effectively no-ops.

usb: Add support to set autosuspend delay by controller driver

USB core driver sets the autosuspend delay to 1 sec for root hub and
its children by default. In case if delay needs to be changed for a
particular controller, it requires class driver to explicitly call
PM API to set the new values. Hence add a call back handler to set
autosuspend delay in controller driver. This makes class driver code
generic.

usb: Decrease autosuspend delay to 200ms upon usb disconnect

Reduce overall HSIC wakelock active time by decreasing autosuspend
delay for HSIC mdm device from 1 sec to 200ms. However when diag is
active it would send poll events for every 500ms causing frequent
supsend/resume. Avoid this by increasing autosuspend delay to 1 sec
when diag is active. Also, set autosuspend delay for root hub to 0 by
default. These changes reduce time HSIC controller is active when the
bus is idle for better power savings.

usb: ehci-msm-hsic: Remove usage of MSM_GPIO_TO_INT

MSM_GPIO_TO_INT is a platform-specific macro that should only
be used in board files, not drivers. In this case, we actually
don't need the GPIO number in the driver itself and only need
to manipulate it using the IRQ number it maps to, so perform the
mapping in the device file.
