Enable support for configuring IOVA alignment since some IOMMU clients
don't require any IOVA alignment and therefore would benefit from the
reduced fragmentation that would result.

Currently the IOVA framework automatically applies IOVA alignment to
provided IOVAs based on the requested IOVA size and the alignment configs
which are enabled.
Some clients who don't require any IOVA alignment would benefit from the
reduced fragmentation that would result from disabling IOVA alignment.
Add support to allow clients to disable IOVA alignment on an IOMMU domain.

Return -ENODEV in case a change_mode command is issued when the system
is in SYS_ASSERT state. This guarantees that the user space application
is aware of the bad state and waits for the FW_READY event.

In case user space application requests for data size which is not a
multiple of the burst size and there is enough data in the drivers internal
buffer, a partial burst may be read by the application, which may cause
loss of burst boundary.
This patch fixes the above. In case the application supplies a buffer which
is smaller than the burst size, an error is returned to the application.

Prevent state changes during DRI handling, which may cause the driver to
get out of synchronization. Prevent data read from user space and from
kernel space during change_mode processing.

32 bit SPI transactions are more efficient. Additionally, the data is
received in the correct endianness, as expected by the host, therefore an
endianness flip can be avoided.

This driver adds support for sensing use cases over 60GHz frequency band.
Sensing uses 60GHz radio signal to 'sense' the environment, allowing
various use cases such as proximity detection, face recognition, gesture
detection and more.
The driver communicates with the QCA6436 HW using SPI bus. The driver
requires SPI and wil6210 drivers to operate.

Userspace sends tcp connection (sock) destroy on network permission
change. Kernel though doesn't send reset for the connections in
SYN-SENT state and these connections continue to remain. Even as
per RFC 793, there is no hard rule to not send RST on ABORT in
this state. Modify tcp_abort and tcp_disconnect behavior to send
RST for connections in syn-sent state to avoid lingering
connections on network switch.
