  msm: pil-modem: Migrate to clk APIs for XO voting
  msm: pil-q6v4: Migrate to clk APIs for XO voting
  msm: pil-riva: Fix error paths when proxy voting fails
  msm: pil-q6v4: Flush instead of cancel delayed work on removal
  msm: pil-riva: Flush instead of cancel delayed work on removal

Use the clock APIs instead of the msm_xo APIs to vote on PXO.
This removes one more msm specific api from this driver and will
allow us to move XO control into the rpm clock driver.

Use the clock APIs instead of the msm_xo APIs to vote on CXO and
PXO. This removes one more msm specific api from this driver and
will allow us to move XO control into the rpm clock driver.

If the proxy voting for CXO or the PLL regulator fails, we should
unwind the work to the state before the failure. Do this so that
users of the driver can recover from errors more easily.

If the pil q6v4 driver is removed or fails to probe we want to
ensure that the proxy votes made during boot are removed even if
they're pending removal. cancel_delayed_work_sync() will ensure
that the proxy vote removal callback no longer runs, but it
doesn't force the callback to run. This means that the proxy
votes stay in place even though the driver has been detached.
Therefore, replace cancel_delayed_work_sync() with
flush_delayed_work_sync() to forcibly remove the proxy votes
before detaching the driver.

QPNP is a Qualcomm SPMI based implementation that specifies 256
devices per SPMI slave ID, with up to 8 interrupts per device.
This brings the theoretical max interrupt support to 32768 per
bus for this architecture.

This header file is added before the driver to satisfy circular
dependency with the PMIC Arbiter driver, which makes calls into
QPNP.

Add pre-divide=6 and update the max period based on new pre-divide.
Also update pre-divide related macros for better readability.

vbus power routine can be different based on platform. If vbus power
sequence is provided using platform data(pdata), disconnect of OTG cable
doesn't turn off the VBUS related regulators and required other
interfaces. This issue is seen as vbus_is_on variable remains always zero
for pdata based vbus routine, and msm_hsusb_vbus_power(motg, 0) doesn't
invoke the required vbus power routine. Hence update the vbus_is_on
variable based on return value of pdata based vbus routine. With this
change, it is mandatory that pdata based vbus routine should return the
success/failure result.

Consider two threads. Thread 1 has an fd linked to an ion buffer
and Thread 2 has a handle to the same buffer. The two came from
the same client

Thread 1                    Thread 2
-----------------------------------------
ion_import_fd
ion_import
mutex_lock(&client->lock)
                            ion_free
                            ion_handle_put
                            ion_handle_destroy
                            mutex_lock(&client->lock) <--- currently locked
ion_handle_lookup
<return reference to same handle>
mutex_unlock(&client->lock)
                            acquire client lock
                            free(handle)

Thread 1 is now holding a reference to an already freed handle.
The issue arises because thread 2 is attempting to destroy the
handle but the handle still exists on the clients list of handles.
This needs to be atomic. Fix this by taking the client lock
around ion_handle_put.

Moving regulators and gpio to board file
GPIO and regulators are usually different for OEM projects.
This will give them the flexibility to support multiple
devices without changing the driver.
