Ringbuffer timer should always be reset whenever we finish
preempting to that ringbuffer. Currently, there is a case where
wptr in the hardware and the kgsl are identical and thus
the timer isn't reset. Reset the timer regardless if they are
identical or not.
There is one special case when we shouldn't reset the timer.
This happens when we try to figure out next ringbuffer to preempt
but the next ringbuffer is the same one as current. In that case,
if nothing new got submitted to this ringbuffer, then don't reset
the timer.

Currently, there is a possibility that read buffers are
not initialized but diag ends up marking buffers busy and
stops reading from peripheral, which leads to port loss.
Also reset the in_busy variable for the buffer that reads
the data from smd channel when diag smd state is closed.

Remove msm_bus bandwidth vote from DT for msm8998
as WLAN FW will take care of it.

Modify ACD_EXTINT_CFG so that ACD calibrates every time OSM toggles
full freq signal. This is recommended by hardware guidelines to
prevent ACD from mitigating when CPU clock frequency is boosted.

Add mem-acc threshold and crossover voltage properties to the
VDD_APC0/1 CPR devices and a matching mem-acc crossover voltage
to the OSM device. Update the APM threshold voltage
to 800 mV for both clusters.

Add support for configuring the highest memory accelerator
(MEM ACC) threshold voltage. This threshold voltage is used at
runtime to determine which CPRh virtual corner to program into
the OSM sequencer registers in place of the fixed MEM ACC
configuration specified in the OSM LUT.

Add support for configuring the memory accelerator (MEM ACC)
threshold voltage and the MEM ACC crossover voltage.
The threshold voltage is used to restrict the floor to ceiling
voltage range of all corners so that they cannot cross the
the MEM ACC threshold voltage due to CPR operation. The
crossover voltage is set when switching the MEM ACC
configuration.
If specified, the APM and MEM ACC crossover voltages are added
to the array of corners after all true corners. If both are
specified, then the APM crossover corner is added before the MEM
ACC crossover corner (i.e. last corner = MEM ACC crossover and
second to last corner = APM crossover).

We want a generic way to insert an RCU grace period before socket
freeing for cases where RCU_SLAB_DESTROY_BY_RCU is adding too
much overhead.
SLAB_DESTROY_BY_RCU strict rules force us to take a reference
on the socket sk_refcnt, and it is a performance problem for UDP
encapsulation, or TCP synflood behavior, as many CPUs might
attempt the atomic operations on a shared sk_refcnt
UDP sockets and TCP listeners can set SOCK_RCU_FREE so that their
lookup can use traditional RCU rules, without refcount changes.
They can set the flag only once hashed and visible by other cpus.
