Remove the secure_camera ctrl_id unless the support is available
from the sde rotator driver. If this id is defined and functionality
is not present in the V4L2 driver it causes the rotator use cases
to fail.

Few alpha PLLs would require to be able to slew in the same VCO mode, which
means the PLL would be able to update the new frequency L value without
turning it off. But to be support this feature the PLL needs to calibrated
at the mid of the VCO range and then enabled.

Add the clock operation list_registers which would print the register
content of a clock. This is supported for PLL/RCG/Branch/Gate clocks.
Also add support for list_rate for the RCG clock which would list all the
frequencies/rates supported by the SW.

Add support for clocks debugfs to be able to display
- rates_max which indicates the frequency to voltage mapping of a clock.
- list_rates, the list of clock frequencies supported by root clocks.
- Also display the rate_max associated with enabled clocks list.

Update clock debugfs to support the below functionalities.
- Allow enable/disable a clock.
- Allow set_rate on a clock.
- Display the list of enabled_clocks along with prepare_count,
enable_count and rate.
- Display the register contents of all the clocks which support
this clock operation.

If a client matching the SVID for an incoming SVDM is found,
assume it has handled the message completely and simply return.
This avoids the case when it handles an Attention message by
queuing another VDM request, only to have it inadvertently
deleted in the generic handling below.
But we also lose tracking of Discover/Enter/Exit Mode
exchanges though that was only used for informational purposes.

With syzkaller help, Marco Grassi found a bug in TCP stack,
crashing in tcp_collapse()
Root cause is that sk_filter() can truncate the incoming skb,
but TCP stack was not really expecting this to happen.
It probably was expecting a simple DROP or ACCEPT behavior.
We first need to make sure no part of TCP header could be removed.
Then we need to adjust TCP_SKB_CB(skb)->end_seq
Many thanks to syzkaller team and Marco for giving us a reproducer.

Sockets can have a filter program attached that drops or trims
incoming packets based on the filter program return value.
Rose requires data packets to have at least ROSE_MIN_LEN bytes. It
verifies this on arrival in rose_route_frame and unconditionally pulls
the bytes in rose_recvmsg. The filter can trim packets to below this
value in-between, causing pull to fail, leaving the partial header at
the time of skb_copy_datagram_msg.
Place a lower bound on the size to which sk_filter may trim packets
by introducing sk_filter_trim_cap and call this for rose packets.
