MSM SDHCI controller doesn't support tuning as specified by the
Standard Host Controller 3.0 spec. As a result of which,
CMD CRC errors are expected for tuning commands. Hence, add a

those errors for tuning commands.

Initial version of Qualcomm SDHC has the following two h/w
issues. This patch adds s/w workarounds for the same.
H/W issue: Read Transfer Active/ Write Transfer Active may be not
de-asserted after end of transaction.
S/W workaround: Set Software Reset for DAT line in Software Reset
Register (Bit 2).
Added a quirk SDHCI_QUIRK2_RDWR_TX_ACTIVE_EOT to enable this workaround.
H/W issue: Slow interrupt clearance at 400KHz may cause host controller
driver interrupt handler to be called twice.
S/W Workaround: Add 40us delay in interrupt handler when operating at
initialization frequency(400KHz).
Added a quirk SDHCI_QUIRK2_SLOW_INT_CLR to enable this workaround.

The data complete interrupt is also used to indicate that a
busy state has ended. Fix a race condition between sdhci_cmd_irq()
that sets any cmd err and sdhci_data_irq() (received to indicate
end of busy state) that clears cmd error. This can happen when a
cmd err is set and finish tasklet is scheduled but sdhci_data_irq()
executes before the tasklet. The cmd err status is critical for the
tasklet handler to reset the controller's state machine. This
should be cleared only when we have successfully processed a sbc
command and are ready to submit the actual command next, not when
there is an actual cmd err.

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.

Port support from 3.10 for retrying cma allocations
to 3.18 to help resolve cma allocation failures.
It was observed that CMA pages are sometimes getting
pinned down by BG processes scheduled out in their exit
path. Since BG processes have lower priority they end up
getting less time slice by scheduler there by consuming
more time to free up CMA pages.
Also when a process is being forked copy_one_pte
may create copy-on-write mappings, when this is done
the page _count and page _mapcount are each
incremented sequentially. If the process is context
switched out after incrementing the _count but before
incrementing the _mapcount then the page will appear
temporarily pinned.
So instead of failing to allocate and directly
returning an error on the CMA allocation path we do 2
retries, with sleeps, to give the system an opportunity
to unpin any pinned pages.

The provision to map 1GB block, gives a problem during

buffers into 4K. During this attempt to remap dma buffers
it overwrites pgd mapping for 1G block, thus leaving an
unmapped hole.
Managing remapping of dma regions with 1G block mapping is
difficult hence avoid mapping 1G block and switch to
SECTION_SIZE mapping (2MB) when memory region overlaps
with dma buffers range.
