The SDHCi driver by default specifies a parameter that causes the
core layer to calculate a max discard value which will be set on the
mmc queue. Unfortunately the value calculated because of this would
be very small compared to what comes in by default. As a result of
this, any secure discard kind of operations are very slow.
Instead add quirk so that any SDHCi hosts that would like to use
the default value can do so.

The BKOPS feature is supported for eMMC cards of version 4.41 and higher.
The BKOPS feature is one time programmable and once it was enabled on
a certain MMC card is cannot be disabled.
LA builds are often being used to verify phones that are targeted for
other HLOSes. Since not all the HLOSes implement the BKOPS features,
enabling this feature by default can cause instability when the phone
will be used by HLOSes other than LA.

Add support to disable available SDHC slots at bootup controlled via a
module param with a bit mask of slots to disable. QDSS is one use case
where SDHC slot is disabled for trace output.
Example Usage:
Passing sdhci_msm.disable_slots=1 as kernel command line argument would
disable SDHC slot 1, whereas passing sdhci_msm.disable_slots=3 would
disable both slots 1 and 2.

USB GSI function driver uses usb_ipa_w work to queue different events
like EVT_CONNECTED, EVT_DISCONNECTED and more. ipa_event_handler()
uses those events as inputs to make necessary decision about performing
connect and disconnect with IPA driver. It is required that before USB
GSI driver calls ipa_usb_deinit_teth_prot(), it has invoked IPA
disconnect API ipa_usb_xdci_disconnect() if it has called
ipa_usb_xdci_connect() API. Current code is making sure that any
running usb_ipa_w work is being completed before calling
ipa_usb_deinit_teth_prot() but if work is not scheduled and pending,
ipa_usb_xdci_connect() is not called (i.e. later when usb_ipw_w work is
scheduled, EVT_DISCONNECTED is being processed but gsi_unbind() has
changed sm_state as STATE_UNINITIALIZED which results into no-ops.)
which results into USB and IPA driver go out of sync in terms of
expected state machine. Hence calling ipa_usb_init_teth_prot() on next
USB cable connect from gsi_bind_config() fails which results into no
USB GSI functionality. Fix this issue by using drain_workqueue() instead
of flush_workqueue() which makes sure that re-queue work is flushed.
