We set hdev->cur_adv_instance in the adv param MGMT request to allow the
callback to the hci param request to set the tx power to the correct
instance. Now that the callbacks use the advertising handle from the hci
request (as they should), this workaround is no longer necessary.
Furthermore, this change resolves a race condition that is more
prevalent when using the extended advertising MGMT calls - if
hdev->cur_adv_instance is set in the params request, then when the data
request is called, we believe our new instance is already active. This
treats it as an update and immediately schedules the instance with the
controller, which has a potential race with the software rotation adv
update. By not setting hdev->cur_adv_instance too early, the new
instance is queued as it should be, to be used when the rotation comes
around again.
This change is tested on harrison peak to confirm that it resolves the
race condition on registration, and that there is no regression in
single- and multi-advertising automated tests.

Some extended advertising hci command complete events are still using
hdev->cur_adv_instance to map the request to the correct advertisement
handle. However, with extended advertising, "current instance" doesn't
make sense as we can have multiple concurrent advertisements. This
change switches these command complete handlers to use the advertising
handle from the request/event, to ensure we will always use the correct
advertising handle regardless of the state of hdev->cur_adv_instance.
This change is tested on hatch and kefka chromebooks and run through
single- and multi-advertising automated tests to confirm callbacks
report tx power to the correct advertising handle, etc.

hci_chan can be created in 2 places: hci_loglink_complete_evt() if
it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory,
Only AMP hci_chan should be removed by a call to
hci_disconn_loglink_complete_evt(). However, the controller might mess
up, call that function, and destroy an hci_chan which is not initiated
by hci_loglink_complete_evt().
This patch adds a verification that the destroyed hci_chan must have
been init'd by hci_loglink_complete_evt().

Currently l2cap_chan_set_defaults() reset chan->conf_state to zero.
However, there is a flag CONF_NOT_COMPLETE which is set when

cleared when l2cap_chan is ready, but when l2cap_chan_set_defaults()
is called, l2cap_chan is not yet ready. Therefore, we must set this

Not cancelling it has caused a bug where passive background scanning is
disabled out of the blue, preventing BLE keyboards/mice to reconnect.
Here is how it happens:
After hci_req_stop_discovery, there is still le_scan_restart_work
scheduled. Invocation of le_scan_restart_work causes a harmful
le_scan_disable_work to be scheduled. This le_scan_disable_work will
eventually disable passive scanning when the timer fires.

Based on device may wakeup status, Bluez stack will enable/disable
passive scanning with whitelist in BT controller while suspending.
As interrupt from BT SoC is handled by UART driver,we need to use
device handle of UART driver to get the status of device may wakeup

Obtain and drive the optional reset GPIO line if this is
not hardwired in the platform. This is needed on the
Samsung GT-I9070 mobile phone.
The invers of power is used, this should be OK to apply
simultaneously as the power signal according to
figures 47-51 on pages 159-161 in the BCM4330 datasheet.

This rewrites the Broadcom bluetooth bindings in YAML and
adds a GPIO handle for the BT_RST_N line as used on some
platforms.
The Ingenic UART binding was using this binding in its
example DTS fragment, however mistakenly using "vcc-supply"
for what is called "vbat-supply". The proper DTS files
and the code in the kernel all use "vbat-supply" so
fix up the example in this patch so we ge a clean
check.

An issue was found, where if a bluetooth client requests a broadcast
advertisement with scan response data, it will not be properly
registered with the controller. This is because at the time that the
hci_cp_le_set_scan_param structure is created, the scan response will
not yet have been received since it comes in a second MGMT call. With
empty scan response, the request defaults to a non-scannable PDU type.
On some controllers, the subsequent scan response request will fail due
to incorrect PDU type, and others will succeed and not use the scan
response.
This fix allows the advertising parameters MGMT call to include a flag
to let the kernel know whether a scan response will be coming, so that
the correct PDU type is used in the first place. A bluetoothd change is
also incoming to take advantage of it.
To test this, I created a broadcast advertisement with scan response
data and registered it on the hatch chromebook. Without this change, the
request fails, and with it will succeed.

During suspend, there are a few scan enable and set event filter
commands that don't need to be sent unless there are actual BR/EDR
devices capable of waking the system. Check the HCI_PSCAN bit before
writing scan enable and use a new dev flag, HCI_EVENT_FILTER_CONFIGURED
to control whether to clear the event filter.
