bam can represent the transport used for the function. Hence change
the name from qcrndis to bam.

Upon cable disconnect usb composition switches from midi
to default composition as a result midi function driver
frees the midi function. When cable is plugged back in
android_setup calls function setup call back for all the
function instances having non-null function pointer. This
results into access to already freed function pointer
stored in function instance. Fix this issue by setting
function instance's function pointer to NULL so that
android_setup will skip calling midi function setup upon
next cable connect.

Some UDC driver doesn't allow or throw errors when USB request buffer
queued is unaligned i.e. buffer size is not equal to wMaxPacketSize or
multiple of wMaxPacketSize. Fix this issue by using 1024 bytes as MIDI
buffer size instead of 256 bytes.

Currently mtp function driver is skipping function
setup call back by not populating function pointer
in function instance. Also, is_ptp flag is set
incorrectly as true for mtp instance which would
pass wrong os descriptor for mtp and ptp instance.
Allow mtp driver to send os descriptor by populating
function pointer in function instance and correctly
set the is_ptp flag to pass valid os descriptors.

On some targets RNDIS function uses BAM to BAM transport, and is
handled by the f_qc_rndis driver. This change adds RNDIS support
using IPA over BAM2BAM. Also removes all different supported control
and data transports and assume BAM2BAM_IPA as default mode. RNDIS UL
changes using software path also removed as IPA supports both UL
and DL on latest products.
DPL support will be added in subsequent patches.

func_name related memory is allocated on creating instance of driver with
cser_set_inst_name() API with usage of kstrndup(). If cser_set_inst_name()
returns non-zero value or driver instance is released, this func_name
related memory is not freed. Fix this memory leak by freeing func_name from
cser_free_inst() API.

It is recommended to use NUM_OF_TRB greater than USB controller's
TRB cache size. Currently USB controller's TRB cache size on GSI
available platform is 12. TRB ring base address must be aligned to
TRB ring length rounded to power of two. Hence set NUM_OF_TRB as
15 for both IN and OUT GSI endpoints.

If user tries to read /dev/usb_accessory node, it results in calling
acc_read() callback. If accessory interface is not present in current
USB composition, it will lead to crash as dev->ep_out is NULL. Fix
the issue by moving problematic code down after device becomes online.

commit <5b42bd749e8c> ("usb: gadget: gsi: Optimize TRB's buffer
allocation functionality") is kicking ipa_work_handler state
machine as part of set_alt() for RNDIS function which results
into giving max_xfer_size_bytes_to_host value as zero as
RNDIS_INIT_MSG from host may not have received here. This results
into low throughput due to device is sending more than accepted
aggregated bytes as part of one USB transfer to host. Fix this
issue by delaying RNDIS IPA initialization till MESSAGE_PACKET_FILTER
is received from host which makes sure that proper aggregation
parameters are passed to IPA driver to configure hardware
accerlerated path.
For non-rndis tethered interface, ipa_usb_notify_cb() posts EVT_CONNECTED
to enable IPA GSI data path (i.e. calling ipa_data_path_enable() API).

wBytesPerInterval in SuperSpeed Endpoint Companion Descriptor needs
to be set large enough to reserve enough bus time for associated
periodic endpoint.
Originally, wBytesPerInterval for mtp's interrupt IN endpoint is set
to 2 and its single interrupt transfer will be split into many 2 bytes
interrupt transfers. So, we change wBytesPerInterval to INTR_BUFFER_SIZE
to ensure interrupt transfer will not be split.

set up a worker for the rx data path but missed a case where the
work_struct needed to be initialized.
This patch adds the missing 'INIT_WORK'

When USB RNDIS network device is bridged with other network device
on windows host machine, it has been observed that many MSG PACKET
FILTER packet with zero and non-zero value are send from host to
device. USB GSI state machine handles those and results into case
where TRB buffer's address is updated wrongly causing bus error
with IPA GSI. Fix this issue as below:
- Move MSG PACKET FILTER handling as part of ipa_work_handler()
- Add blocking USB3 ringing doorbell on receiving MSG PACKET FILTER
with non-zero value.
- Before processing HOST_NRDY event, see already posted event. If it
is HOST_READY event, then ignore HOST_NRDY and HOST_READY to avoid
performing operations related to HOST_NRDY and HOST_READY again.

There is delay seen in queueing notification when response is
available after performing function remote wakeup. This change
queues control notification from gsi_resume() for RMNET/MBIM and
ECM case when notify_count is 1 (i.e. remote wakeup is performed
but notify request is not queued.) to make sure that host is
notified before it timeouts for response and starts data transfer.

If accessory driver setup fails then _acc_dev points to
freed memory and later drivers crashes on disconnect
due to invalid memory access. Mark _acc_dev only if
acc_setup is successful to prevent the crash.

Currently USB driver is resetting strings like manufacturer, model
to zero as part of handling control request for protocol version. Some
accessory docks may not send manufacturer and model strings before sending
control request to enable audiosource USB composition. This results in
userspace enabling audio source composition without accessory interface.
If accessory dock is connected during bootup, accessory timeouts in
configuring android device and results in detection failure. Userspace does
have recovery mechanism if incase accessory dock timeouts to configure
android device in accessory composition. Hence set manufacturer and model
strings to default value so that userspace enables accessory + audiosource
composition for userspace recovery to be working and detecting accessory
dock successfully during bootup.

Synopsys USB3 Controller (DWC3) has a restriction where size
of OUT requests (TRB) queued to the controller must be aligned
with the endpoint's max packet size. Generally, accessory userspace
module submits RX requests not aligned to endpoint's max packet
size. Hence to overcome this, align the size of RX request buffer to
endpoint's max packet while submitting to DCD as the buffers are
already allocated with the size of 16KB.

This reverts commit 9d6fd2c3e9fcfb ("Merge remote-tracking branch
'msm-4.4/tmp-510d0a3f' into msm-4.4"), because it breaks the
dump parsing tools due to kernel can be loaded anywhere in the memory
now and not fixed at linear mapping.
